Sustainable carbon nanomaterials : Delving into its biomolecular interactions, responses and applications

Abstract

The investigation embodied in the thesis entitled “SUSTAINABLE CARBON NANOMATERIALS: DELVING INTO ITS BIOMOLECULAR INTERACTIONS AND RESPONSES” was initiated in June 2016 in the Discipline of Metallurgy Engineering & Materials Science, Indian Institute of Technology Indore. The objectives of this thesis are exploration of graphene and carbon dot synthesis by employing green source, its biomolecular interactions, responses and suitability for biomedical applications. The focal points of the thesis are as follows 1. Direct exfoliation of graphite to graphene using a sustainable source. 2. Investigation of biocompatibility and protein interactions on exfoliated graphene. 3. Exploration and applicability of c-dots for graphene exfoliation, its stabilization and biological activity. 4. Green synthesis of c-dots for optical sensing of biomolecules, physical entity and bioimaging. 5. Modulation of fluorescence performance of c-dots through functional group tuning. This thesis comprises seven chapters.
