Integrated p-NOI Structures on Nanoporous Material Designed for Biodetection

Abstract

Pesticides are utilized to protect the crops, destroying or controlling any pest. Unfortunately, pesticides pollute the entire environment: plants, organisms, soil, and water. This chapter describes a paraoxon pesticide biosensor that includes nanostructures and porous materials integrated on silicon (Si), as convergent objectives of the green microelectronics strategy. The transducer element is in an interdigitated capacitive electrode that recently highlighted a special nanostructure-the planar nothing on insulator (p-NOI)-included in the capacitive detection system. The biodetection is based on the hydrolysis of the acetylcholinesterase (AChE) enzyme as biosensor receptor. So, the final application is an enzymatic biosensor that utilizes the nanoporous Si layer for the enzyme adsorption, with p-NOI capacitive transducer, for the environmental monitoring.

Bioelectronics and Green Electronics for a clean Environment

“…We mention some solutions from Bio-Nano-Electronics and Micro-technologies fields: (i) for the reduction of gases and CO-emission, the Si electronics must move to SiC or C electronics, due to a strong minimization of the leakage currents in all CMOS circuits in OFF-state; (ii) different sensors and biosensors for water/air/soil monitoring manufactured by micro-nano-electronics technologies (Ravariu C et al, 2018); (iii) recuperation of rare metals or critical Terra resources from electronic wastes (e.g. Hf, Pt etc); (iv) green organic semiconductor processes of fabrications (Ravariu C. et al, 2020); examples are nano core materials with organic shell instead of materials for electronics with PAH precursors, like usual pentacene (Yang D. et al, 2015); (v) environmental monitoring, clean medicine (Bondarciuc A et al, 2015), environmental education and common practices for people from different countries to enlarge the common initiatives.…”
