1. INTRODUCTION Detection of chemical and biological agents plays a fundamental role in
biomedical, forensic and environmental sciences 1− 4 as well as in anti bioterrorism …

Highly fluorescent, water-soluble, few-atom noble-metal quantum dots have been created
that behave as multielectron artificial atoms with discrete, size-tunable electronic transitions …

Nano-is a big prefix-word. Much of contemporary chemistry focuses on small scale
structures, and indeed, molecular science is intrinsically on the nanometer scale. Selecting …

Branched polyethylenimine (PEI) chains with an average molecular mass of 2 kDa (PEI2)
have been covalently attached to gold nanoparticles (GNPs), and the potency of the …

We use 1H and 31P solution nuclear magnetic resonance spectroscopy to analyze the
binding of phosphonic acid ligands to wurtzite CdSe quantum dots (CdSe QDs). CdSe QDs …

We demonstrate that the amino acid tyrosine is an excellent reducing agent under alkaline
conditions and may be used to reduce Ag+ ions to synthesize stable silver nanoparticles in …

This review examines the use of self-assembled monolayers (SAMs) on gold as nanoscale
protective coatings for both nominally flat substrates and for nanoparticles. The thermal and …

Following elucidation of the Brust protocol for the synthesis and capping of gold colloids with
alkanethiols in nonpolar organic solvents, 1 there have been a number of reports on the …

The synthesis of water-dispersible amino-acid-protected gold nanoparticles by the
spontaneous reduction of aqueous chloroaurate ions by tryptophan is described. Water …

Gold nanoclusters (AuNCs) have shown great promise for in vivo imaging because of their
definable structure, tunable photoluminescence (PL), and desired renal clearance …
