Upconversion nanoparticles, which do not suffer from the photophysical artifacts limiting fluorescent molecules, offer an exciting opportunity for biological super-resolution imaging. We develop an efficient STED mechanism using lanthanide upconversion nanoparticles, enabling cytoskeleton nanoscopic imaging.

It is demonstrated that the performance of organic solar cells can be improved by doping PEG-coated Gold Nanorods in the active layer with 10.6% increase in the power conversion efficiency.

We for the first time proposed a facile supercontinuum-based broadband (theoretically above 3500 cm-1) stimulated Raman scattering spectral bioimaging microscopy. The sample of water-lipid mixture was spectrally resolved imaging with efficient time-delay adjustment.

We propose a novel multi-photon evanescent wave (MPEW) excitation modality for upconverting nanoparticles (UCNPs) based microscopy. Experimental results show this new imaging method for UCNPs is nonscanning, ultrahigh contrast and high spatiotemporal resolution.

We report an effective method to synthesize gold nanorods with tunable longitudinal extinction peak wavelength from 781 to 955 nm depending on the amount of NaCl added. Those as-prepared gold nanorods are helpful for bioimaging.

Enhancement of fluorescence of streptavidin conjugated with gold nanorods (GNRs) was observed. The impact of GNRs with different surface plasmon resonance bands and different concentrations to the efficiency of the fluorescence enhancement was studied.
