Simple approach for high contrast optical imaging and characterization of graphene based sheets


Optical Imaging Characterization of Graphene Other 2D Materials for Using Quantitative Phase Microscopy. By using an optical imaging method combined with image analysis software, a high‐ contrast image of the MoS 2 sheets can be extracted from the red ( R) channel of the color optical microscopy image. In addition promising approaches simple based on transfer printing of exfoliated graphene onto electrodes on different substrates for large- scale integration have been reported recently 7, for 8 9.

Functionalized graphene oxide is a novel type of highly efficient biosensing material. In this study, we present a carboxyl- functionalized graphene oxide ( GO- COOH) - based surface plasmon resonance ( SPR) chip for the rapid and quantitative detection of non- small cell lung carcinoma ( NSCLC) via the cytolerayin 19 ( CK19) protein biomarker in spiked human plasma.
