Electromagnetic Activation of Salicylic Acid in a Complex with Oxidized Zinc-graphene Structure

Abstract

This work aims at the development of a method of electromagnetic activation of salicylic acid molecules per se (SA) through the ultrasonic (20 kHz) complexation with oxidized zinc-graphene structure. The result of this work implies synthesized nanopartiсles “ZnO – partially restored graphene oxide (rGO) – SA” with the average size of (5.53 ± 0.11) nm and hexagonal wurtzite zinc oxide structure with complexed SA molecules. Complexation of SA with “ZnO – rGO” matrix causes magnification of electromagnetic field of SA by 10² times with the local enhancement at the contact with ZnO by 10³ times, and therefore allowing selective electromagnetic activation of drug molecules. The developed method of “ZnO – rGO – SA” nanoparticles formation can be applied to many different drugs and drug-based devices, thereby introducing a great interest in medicinal electronics and nanomedicine.
