Objective: Chloramphenicol and tetracycline are broad-spectrum antibiotics and widely used against variety of microbial infections. Nowadays, several microbes have acquired resistance to chloramphenicol and tetracycline. The present study was aimed to evaluate the impact of biofield treatment for spectroscopic characterization of chloramphenicol and tetracycline using FT-IR and UV-Vis spectroscopy. Methods: The study was performed in two groups (control and treatment) of each antibiotic. The control groups remained as untreated, and biofield treatment was given to treatment groups. Results: FT-IR spectrum of treated chloramphenicol exhibited the decrease in wavenumber of NO2 from 1521 cm-1 to 1512 cm-1 and increase in wavenumber of C=O from 1681 cm-1 to 1694 cm-1 in acylamino group. It may be due to increase of conjugation effect in NO2 group, and increased force constant of C=O bond. As a result, stability of both NO2 and C=O groups might be increased in treated sample as compared to control. FT-IR spectrum of treated tetracycline showed the downstream shifting of aromatic C-H stretching from 3085-3024 cm-1 to 3064-3003 cm-1 and C=C stretching from 1648-1582 cm-1 to 1622-1569 cm-1 and up shifting of C-N stretching from 965 cm-1 to 995 cm-1. It may be due to enhanced conjugation effect in tetracycline, and increased force constant of C-N (CH3) bond of tetracycline as compared to control. The results indicated the enhanced stability of treated tetracycline as compared to control. UV-Vis spectra of biofield treated chloramphenicol and tetracycline showed the similar lambda max (λmax) to their respective control. It revealed that the chromophore groups of both antibiotics remained same as control after the biofield treatment. Conclusion: Based on FT-IR spectroscopic data, it is speculated that due to increase in bond strength and conjugatio

Chloramphenicol and tetracycline are structurally dissimilar broadspectrum antibiotics that commonly act by inhibiting the protein synthesis in microbes. These are extensively used in several microbial infections including Gram-negative, Gram-positive bacteria, chlamydiae, and rickettsiae [1-3]. Chloramphenicol reversibly binds to 50S ribosomal subunit of microbes and prevents the binding of aminoacyl tRNA to 50S ribosomal subunit. Thus, it inhibits protein synthesis in bacteria, which is essential for bacterial growth [3,4]. Despite of its broad spectrum antimicrobial activities, it also has some adverse effects such as gray baby syndrome, aplastic anemia, and bone marrow depression [3,5]. Nowadays, chloramphenicol is not much effective due to development of resistance in the variety of microbes. Microbial resistances against chloramphenicol occur by several mechanisms like enzymatic (acetyltransferases and phosphotransferases) inactivation; decreasing the membrane permeability, mutation/modification in target site, and presence of efflux pumps [6]. Tetracycline exerts both bacteriostatic and bactericidal mode of action against the majority of aerobic, anaerobic, Gram-negative, and Grampositive bacteria. It binds with 30S ribosomal subunit of microbes and block the binding of activated aminoacyl-tRNA to the A site of ribosome. Thus, it blocks the insertion of new amino acids to the nascent peptide chain [2,7,8]. Microbes acquire resistance to tetracycline by evolving the efflux pump and/or by ribosomal protection protein [9,10].
Antimicrobial resistance is now conceiving as global threat; as a result need of new antimicrobial drugs is constantly increasing.
Therefore, global scientific community has attempted to discover a concept to overcome the microbial resistance i.e. reintroduction of previously used antibiotics active against multi drug resistant (MDR) bacteria. Therefore, several antimicrobial agents like chloramphenicol, tetracycline, etc are reemerging after some modifications as valuable alternatives for the treatment of difficult-to-treat microbial infections [11,12].
Stability of drug is of great importance for its efficacy. In addition, drug degradation may lead to byproducts formation. Abachi et al. showed that stability of chloramphenicol was independent of pH between 4 to 6.2, and it was susceptible to hydrolysis in aqueous media [13]. Lv et al. suggested that chloramphenicol was not stable in suspension form [14]. Liang et al evaluated the stability of tetracycline in methanol solution using UV–Visible spectroscopy, HPLC, and TLC methods. The report showed that tetracycline decomposed quickly with the influence of light and atmospheric oxygen, and formed several degradation products [15,16]. Therefore, an alternative approach is needed that can increase the shelf life of poorly stable drug.
Recently an alternative approach, biofield treatment is recognized to change the various physical and structural properties at the atomic level of various living and non-living things. It is well established that electrical current coexist along with the magnetic field inside the human body in the form of vibratory energy particles like ions, protons, and electrons [16,17]. Willem Einthoven discovered an electrocardiography in 1924 to measure the human biofield. Later on, Harold Saton Burr gave the hypothesis that every dynamic process in the human body had an electrical significance. Recently, it confirmed that all the electrical process happening in human body generates magnetic field [18]. It can be observed using some medical technologies such as electrocardiography, electromyography, and electroencephalogram. The electromagnetic field of the human body is known as biofield and energy linked with this field is called biofield energy [19-21]. Thus, a human has the ability to harness the energy from environment or universe and can transmit into any living or nonliving object around this globe. The object(s) always receive the energy and responding into useful way; this process is known as biofield treatment (The Trivedi Effect®). Mr. Trivedi’s biofield treatment has altered the physicochemical and structural properties of metals and ceramics [22-24]. The growth and anatomical characteristics of medicinal plant also changed after biofield treatment [25]. The biofield treatment enhanced the yield and quality of agriculture product [26]. Moreover, the changes in antimicrobial susceptibility and biotype number of pathogenic microbe have been reported after biofield treatment [27].
Conceiving the concept of antimicrobial reuses, the present study was aimed to evaluate the impact of biofield treatment on spectral properties of two antibiotics i.e. chloramphenicol and tetracycline.
Materials and Methods
Study design
The chloramphenicol and tetracycline (Figure 1) samples were procured from Sigma-Aldrich, MA, USA; and each antibiotic was divided into two parts: control and treatment. The control samples remained as untreated, and treatment samples were handed over in sealed pack to Mr. Trivedi for biofield treatment under laboratory condition. Mr. Trivedi provided this treatment through his energy transmission process to the treatment groups without touching the objects. After that, the control and treated samples of each antibiotic were analyzed using Fourier transform infrared (FT-IR) spectroscopy and Ultraviolet-Visible (UV-Vis) spectroscopy.
FT-IR spectroscopic characterization
FT-IR spectra were recorded on Shimadzu’s Fourier transform infrared spectrometer (Japan) with frequency range of 4000-500 cm-1. The FT-IR spectral analysis of chloramphenicol and tetracycline were carried out to evaluate the impact of biofield treatment at atomic level like bond strength, stability, and rigidity of chemical structure [28].
UV-Vis spectroscopic analysis
UV-Vis spectra of chloramphenicol and tetracycline were acquired on a Shimadzu UV-2400 PC series spectrophotometer with 1 cm quartz cell and a slit width of 2.0 nm. The analysis was carried out at wavelength range of 200-400 nm. UV-Vis spectroscopic analysis was performed to evaluate the effect of biofield treatment on structural property of tested antibiotics (chloramphenicol and tetracycline) [28].
Results and Discussion
FT-IR spectroscopic analysis
FT-IR spectra of control and treated chloramphenicol are shown in Figure 2. FT-IR spectrum of control sample showed absorption peaks at 3352-3246 cm-1 that were assigned to O-H and N-H stretching, respectively. IR peaks at 3081 cm-1 were assigned to aromatic C-H stretching. Vibrational peaks at 1681 and 1559 cm-1 were assigned to C=O and C=C stretching, respectively. Further, the NO2 and C-Cl stretching were observed at 1521 cm-1 and 662 cm-1, respectively; and N-H bending was appeared at 1518 cm-1. The FT-IR data of control chloramphenicol was well supported by the literature data [29].
The FT-IR spectrum of treated sample of chloramphenicol showed IR absorption peaks for O-H and N-H stretching at 3243 cm-1 and aromatic C-H stretching was appeared at 3079 cm-1. The vibrational peak of carbonyl group (C=O) and C=C stretching were attribute to IR peaks at 1694 and 1560 cm-1, respectively. Additionally, NO2 stretching and N-H bending peaks were appeared at 1512 and 1510 cm- 1, respectively; and C-Cl stretching was appeared at 667 cm-1.
Altogether, the result suggested that C-H and C=C stretching peaks of aromatic ring were observed in similar frequency region in both control and treated sample of chloramphenicol. It indicated that stability and rigidity of phenyl ring was retained in treated sample as like to control. The vibrational peaks for C=O stretching (acylamino group) was observed towards higher frequency region i.e. from 1681 to 1694 cm-1 that may be due to an increase in force constant of C=O group in treated chloramphenicol. Further, FT-IR spectra of treated chloramphenicol showed decrease in wavenumbers of NO2 i.e. from 1521 to 1512 cm-1. It might be occurred due to increase of conjugation effect between NO2 group and phenyl ring [30]. Force constant is directly proportional to bond strength [28]. As the force constant of C=O was increased due to biofield treatment, the stability of acylamino moiety in treated chloramphenicol should also be increased. Additionally, the conjugation effect between NO2 group and phenyl ring may lead to increase in chemical stability of treated chloramphenicol as compared to control.
The FT-IR spectra of control and treated samples of tetracycline are shown in Figure 3. FT-IR spectrum of control sample showed the absorption peaks for N-H and O-H stretching at 3341-3329 cm-1 and aromatic C-H stretching at 3085-3024 cm-1. The vibrational peaks at 2995-2863 cm-1 and 1648-1582 cm-1 were assigned to CH3 stretching and C=C stretching, respectively. Aromatic C-H bending was appeared at 1458 cm-1 and CH3 bending was appeared at 1357 cm-1. The aromatic in plane and out plane deformation peaks were appeared at 1247-1000 cm-1 and 567-501 cm-1, respectively. Vibrational peak at 965 cm-1 was assigned to C-N stretching. The FT-IR data of control sample was well supported by reported data [31].
The FT-IR spectra of treated tetracycline showed the vibrational peaks at 3342-3325 cm-1 that were attributed to N-H and O-H stretching. Vibrational peaks at 3064-3003 cm-1 and 2955-2835 cm-1 were assigned to C-H and CH3 (methyl) stretching, respectively. C=C stretching peaks were appeared at 1622-1569 cm-1. Bending vibrational peaks for C-H and CH3 groups were appeared at 1454 and 1357 cm-1, respectively. Vibrational peaks at 1247-1000 cm-1, and 995 cm-1 were assigned to C-H in plane deformation and C-N stretching, respectively. The out plane ring deformation peaks were appeared 567-501 cm-1.
The FT-IR data of control and treated tetracycline showed that N-H and O-H stretching peaks are observed in the similar frequency region in both samples. This suggests no changes in the amide and hydroxyl group of treated tetracycline as compared to control. IR absorption peaks for C-H (aromatic) stretching were shifted to lower frequency i.e. from 3085-3024 cm-1 to 3064-3003 cm-1 and likely the CH3 stretching was shifted to lower frequency i.e. from 2995-2863 cm-1 to 2955-2835 cm-1. IR absorption peak for C=C stretching was also appeared at lower frequency region i.e. form 1648-1582 cm-1 to 1622-1569 cm-1 in treated sample as compared to control. It is well known that resonance or conjugation of C=C double bond or carbonyl group provides the more single bond character to C=C bond that lowers the force constant of respective bond [28,30]. Further, resonance and/or conjugation effect also provide the stability to chemical compound. Therefore, it is speculated that biofield treated tetracycline might be more chemically stable due to enhanced conjugation effect in C and D ring, with respect to control. This could be correlated to enhancement in stability of treated tetracycline with respect of control. The C-N stretching peak in treated tetracycline was observed at higher wavenumber than control (i.e. from 965 to 995 cm-1). It could be due to increased bond strength of C-N (CH3) group that might be increased stability of treated tetracycline as compared to control.
UV-Vis spectroscopy
UV spectra of control and treated samples of chloramphenicol are shown in Figure 4. It showed no significant change in the lambda max (λmax) of treated sample (273.8 nm) as compared to control (272.2 nm), which indicated no changes in chromophore group of treated chloramphenicol with respect to control. UV spectra of control and treated sample of tetracycline are shown in Figure 5. Both spectra showed three absorption peaks at 362.60, 268.80, and 220.60 nm in control sample and 362.60, 268.80, and 221 nm in treated sample, which indicated similar pattern of UV absorbance in both the samples. This suggested no changes in chromophore group of treated tetracycline with respect to control. Overall, the UV spectra of both the antibiotics showed no significant changes in λmax as compared to control. Based on this, it could be concluded functional groups or their position did not altered in treated sample after biofield treatment. To the best of our knowledge, this is the first report showing an impact of biofield treatment on spectral properties (force constant, dipole moment, and bond strength) of chloramphenicol and tetracycline as compared to control.
Altogether, the FT-IR data showed an alteration in the wavenumber of some functional groups like C=O and NO2 in chloramphenicol and C=C and C-N (CH3) in tetracycline with respect to control groups. This could be observed due to some alteration at the atomic level of both antibiotics by the influence of biofield treatment. The results of present study suggest the impact on force constant, bond strength and dipole moment of both antibiotics that may be alter the chemical stability of biofield treatment as compared to control.
