Molecules with Biological Interest Adsorbed on Carbon Nanostructures

Abstract

In the last decade, carbon nanostructures have been exhaustively studied mainly associated with their application in biosensors and drug delivery systems. In this context, the present chapter introduces several studies combining amino acids and pharmaceutical drugs with carbon nanostructures such as graphene, carbon nanotubes and fullerene. More specifically, the biomolecules under focus are the amino acid cysteine and the pharmaceutical drugs nimesulide, meloxicam and zidovudine. These molecules can be considered models for different chemical interactions or adsorptions with carbon nanostructures. The adsorptions analysed suggest possible applications such as biosensors or drug delivery depending on the use of particular pristine or functionalised carbon nanomaterials.
