16.1 Introduction

Bioelectronics is an emerging field of materials science, which integrates novel and smart

materials with the biological world and will act as a bridge between the electronic and

biological domains. With the progress in the development of intelligent bioelectronic de­

vices, the field of bioelectronics has revolutionized the 21st century and has been emerged

as an exhilarating field. [1–3]. The technology behind bioelectronics encompasses the sy­

nergy of biological materials and biological architecture for information processing and

device fabrication. The significant perception of bioelectronics is the transduction of the

biological signals to electrical signals at the sensing interface and the functionality of these

devices is controlled by the chattels of the interface between the bioelectronic materials and

biological systems [4,5].

Bioelectronic applications have gained excessive interest in recent years owing to their

mesmerizing characteristics such as flexibility, low cost, nontoxicity, large-volume elec­

tronic components, sustainability, biocompatibility, biodegradability, and bioresorbable

nature [6]. The miniaturization of nanomaterials such as semiconductors together with

biological moieties has opened new horizons in biomedical research, health care, and

commercial medical applications. The adaptability of bioelectronics applications in the

arena of organic field-effect transistors and biosensors, promises a bright future. Nanoscale

bioelectronics has led to the development of molecular-based personalized medicines. Also,
