Nano Science

Fullerenes, carbon nanotubes ,carbon dots, carbon nano onions, graphene, graphene quantum dots and their water soluble versions with easy and novel synthesis and related chemistry has been developed. Their use in biochemical/biomedical applications like life cycle imaging of living laboratory animals, drug carrier and drug delivery were pursued . Development of composite materials with nano stuff has been made for catalytic functions. The composite assembly of carbon materials with structurally characterized compounds or substrate based assembly of simple inorganic complexes led to aggregation with different shapes and sizes from atomic scale to several micrometer size retaining the original identity to mimic stem cell . A DNA-nano carbon synthetic biology has been introduced. The toxicity issue of nano carbons have been studied in details and two forms of nano carbons as one set with defect free are toxic which are used in electronics and cannot be readily made hydrophilic and the other version with defects are readily derivatised introducing carboxylic and hydroxyl groups are consumed by human along with roasted food since the discovery of fire ( Mesolithic age) have been made.
