Abstract
W e have developed a novel biocomposite material for the electrocatalysis of p-acetamidophenol using Multi-walled carbon nanotubes (MWCNTs) and poly (aniline) and poly (fl avin adenine dinucleotide) copolymer (PANIFAD) at gold electrode and screen printed carbon electrodes (SPCE). Th e developed MWCNTs-PANIFAD biocomposite fi lm for the electrocatalysis combines the advantages of ease of fabrication, high reproducibility and suffi cient long-term stability. In another approach we have fabricated metal hexacyanoferrates- conducting polymer fi lm based sensor for the simultaneous determination of p-acetamidophenol and ascorbic acid. We proposed easy and convenient method for the detection and determination of melamine by employing oxidized polycrystalline gold electrode (poly GE). Th e poly GE successfully detects the melamine signal (0.06-0.85 ppm) in tainted milk powder samples. It also exhibited two well-separated anodic oxid ation peaks for urine and melamine in melamine- spiked human urine samples with high sensitivity. We used simple preanodized SPCE for the electrochemical detection of a hypnotic agent propofol. Th e preanodized SPCE is found to be much eff ective for the detection of propofol in physiological pH conditions. Furthermore, the proposed SPCE overcomes the interference eff ects and eff ectively shows the oxidation peaks for the detection of propofol in urine samples. Nano TiO2 -conducting polymer, poly(3,4- ethylenedioxythiophene) (PEDOT) composite modifi ed electrodes for the detection of Diclofenac which is an essential anti-infl ammatory drug to reduce infl ammation.
