| Outline of Annual Research Achievements |
The present research project was focused on exploring a new chemical approach for functionalization of graphene with different active end groups through direct binding of transient radical species formed in a reaction mixture. As we know that -SH functionalized surface is technologically very important because of its higher affinity toward nano-particles and bio-moelcules. Hence I have performed and succeeded in functionalization of graphene with SH group followed by covalent immobilization of gold nanoparticles (AuNPs).I found that the immobilized AuNPs can further be functionalized with other functional molecules such as pentachlorobenzenethiol and hexanedithiol. This findings is an step forward for the development of graphene based ultrasenstive chemical and biosensors.
