Abstract :

The ability to different various neuropeptides in human organism and evaluation of their amount are very significant in neuropsychology and physiology. Last time, the localized surface plasmon resonance (LSPR) was widely introduced into biosensing. Sensitivity of optical biosensors was significantly improved using metal nanostructures based in general on the application of gold and silver. Nanostructures prepared from these metals appear LSPR in the visual and near infrared spectrum. However, the difference in the neuropeptides come out in the middle and deep ultraviolet spectrum where gold and silver are inapplicable. It is known that aluminum nanostructures can display the LSPR in the ultraviolet spectrum. However, there are some difficulty in the aluminum nanostructure preparation due to its easily oxidation and good adherence to the glass. In this work, we present a simple method for preparation the aluminum nanostructures consisting of aluminum nanoparticles surrouned by a thin layer of aluminum nitride.
