Metal nanoparticles are being extensively used in various biomedical applications due to their small size to volume ratio and extensive thermal stability. Gold nanoparticles (GNPs) are an obvious choice due to their amenability of synthesis and functionalization, less toxicity and ease of detection. The present review focuses on various methods of functionalization of GNPs and their application...

The verification of a successful covalent functionalization of graphene and related carbon allotropes can easily be carried out by Raman spectroscopy. Nevertheless, the unequivocal assignment and resolution of individual lattice modes associated with the covalent binding of addends was elusive up to now. Here we present an in situ Raman study of a controlled functionalization of potassium inter...

Biochemical functionalization of surfaces is an increasingly utilized mechanism to promote or inhibit adhesion of cells. To promote mammalian cell adhesion, one common functionalization approach is surface conjugation of adhesion peptide sequences such as Arg-Gly-Asp (RGD), a ligand of transmembrane integrin molecules. It is generally assumed that such functionalization does not alter the local...

C–H Functionalization has the potential to become a paradigmshifting strategy for organic synthesis. Over the last decade, the field has experienced explosive growth and a large variety of new C–H functionalization methodologies have been developed. In particular, regioselective functionalization of sp2 C–H bonds has become a broadly flexible approach for the synthesis of complex aromatic carbo...

Chemical Functionalization is a technique used to increase the dispersion and solubility of single-walled carbon nanotube (SWCNT). Functionalization of a (10, 0) zigzag nanotube segment containing 80 C atoms was investigated with the aide of spinunrestricted density functional theory (DFT). The (10, 0) was funtionalized with three organic acid groups: (a) carboxylic acid, (b) aromatic dicarboxy...

The coupling of ligand-stabilized gold nanoparticles with field-effect devices offers new possibilities for label-free biosensing.
