A Perspective on Atomically Thin 2D Inorganic Layered Materials for Biosensor

Abstract

The 2D inorganic materials have ability to play important role in the designing of novel biosensor devices for the future. The advantages are originated from their unique electronic and optical properties along with large area available for the biofunctonalization. We have attempted to address few challenges and issues for developing biosensors based on 2D materials for practical applications for enhanced life time, improved durability, and biocompatibility. Use of 2D nanocomposites materials and doping them using various noble metals will be very exciting and challenging areas of research for future biosensor to be explored to achieve selectivity and high sensitivity with very low detection limit. In next phase of structural DNA/ RNA nanotechnology in combination with 2D inorganic layered materials, novel interactions can expected between DNA, RNA, 2D inorganic layered materials and proteins. This has direct relevance to develop new molecular design, computing facility, programming and assembly of the new functional materials.
