Highly fluorescent, water-soluble, size-tunable gold quantum dots.
TLDR
Highly fluorescent, water-soluble, few-atom Au quantum dots have been created that behave as multielectron artificial atoms with discrete, size-tunable electronic transitions throughout the visible and near IR.Abstract:
Highly fluorescent, water-soluble, few-atom Au quantum dots have been created that behave as multielectron artificial atoms with discrete, size-tunable electronic transitions throughout the visible and near IR. Correlation of nanodot sizes with emission energies fits the simple relation, ${E}_{\mathrm{F}\mathrm{e}\mathrm{r}\mathrm{m}\mathrm{i}}/{N}^{1/3}$, predicted by the jellium model. Providing the ``missing link'' between atomic and nanoparticle behavior in noble metals, these emissive, water-soluble Au nanoclusters open new opportunities for biological labels, energy transfer pairs, and light emitting sources in nanoscale optoelectronics.read more

Nonlinear structured-illumination microscopy: Wide-field fluorescence imaging with theoretically unlimited resolution
TL;DR: Experimental results show that a 2D point resolution of <50 nm is possible on sufficiently bright and photostable samples, and a recently proposed method in which the nonlinearity arises from saturation of the excited state is experimentally demonstrated.
