Graphene based Nanostructures and DNA based Biomolecule Sensors

Abstract

This research work contains three main parts. The first part is to investigate the electrical conductivity and dielectric properties of PMMA/Graphene Nanoplatelet composites withan emphasis on the percolation threshold. The second part is the study of a graphene-based FET structure including modelling the FET characteristics based on device theory calculation and simulation, and utilizing Raman Spectroscopy and Surface-Enhanced Raman Spectroscopy to verify active molecular components inside synthesized nanostructures. The third part is the sensor experiment part, which includes design, fabrication and testing of two biomolecu-lar sensors using optical photolumescence measurements and graphene-based electrochemical measurements, respectively.
