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

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.
