Abstract
Monolayer-protected gold nanoparticles were prepared using several different synthetic methods. The prepared nanoparticles were characterized by UV-visible spectroscopy, cyclic voltammetry (CV), differential pulse voltammetry (DPV), and mass spectrometry. Different thiols were used in the synthetic scheme in order to monitor differences in surface chemistry. A study of quantum yield in waterÂsoluble, monolayer-protected quantum dots (QDs) was completed. The study examined the changes in quantum yield from the effects of heating, method of selenide addition, type of surrounding thiol, and material lifetime. Subsequent modifications of the QD surface were characterized using electrochemistry.
