Development of graphene sensing platforms for real time diagnostics

2nd International Conference on Materials Science and Materials Chemistry
March 20-21, 2019 | London, UK

Owen J Guy

Swansea University, UK

Keynote : Mater Sci Nanotechnol

Abstract:

Graphene is a 2D material with unique electrical and mechanical properties. Graphene devices and sensors promise to be a disruptive technology in next generation electronics and sensors - due to graphene’s exceptional electronic properties and aptitude for chemical modification. Novel graphene sensor technology used to develop sensors, based on chemically functionalised graphene microchannels, and their application in lab-on-chip POC (Point-of-Care) diagnostics will be presented. There are several advantages of graphene sensors over alternative sensor platforms such as carbon nanotubes (CNTs) or silicon nanowires (SiNWs). The main benefits of graphene for sensing applications will be highlighted in a comparison with other materials. Real time sensing using graphene Field Effect Transistors (FETs) will be presented. Important considerations for processing of samples using microfluidics and lab-on-chip technology will also be discussed, including developments in integration of diagnostics with therapeutics, “theranostics”.
