We introduce a bifocal imaging method that enables three-dimensional (3D) tracking of both fluorescent and nonfluorescent particles. We accomplish this by simultaneously imaging a focused plane, for in-plane position (x,y), and a defocused plane, for out-of-plane position (z), of a molecule using a single CCD camera. We applied our method to several systems including in vivo melanosome tracking...

Blue emission fluorescent Au(5) clusters with maximum quantum yield of 20.1% were synthesized by a simple photoreduction method using three specially designed tridentate polymer ligands. The evolution of fluorescent Au nanoclusters (Au NCs) under UV irradiation was studied by fluorescence, UV-Vis and X-ray photoelectron spectroscopic techniques, suggesting that the fluorescence of Au NCs is siz...

Femtosecond laser microsurgery has become an advanced method for clinical procedures and biological research. The tissue treated by femtosecond laser can become highly fluorescent, indicating the formation of new fluorescent compounds that can naturally label the treated tissue site. We systematically characterized the fluorescence signals produced by femtosecond laser ablation in biological ti...

six fluorescent compounds were isolated and characterized in rhizomorph of a. mellea and were presented first as: f , f , f , mf , mf and mf . these compounds differed by rf on chromatoplaque, max in uv spectra and ex, em and max in fluorescence spectra. their gc-ms analysis indicated that f has a phenolic moiety and the other five are the benzenic derivatives. f compound was more fluorescent r...

BACKGROUND/PURPOSE To develop modification of stripping method allowing high-resolution fluorescent visualization of corneocytes of human skin in vitro. To validate the method, the measured corneocyte areas on skin flakes are collected from individuals of different ages. MATERIALS AND METHODS Two complimentary fluorescent dyes were used sequentially. First the adhesive layer of the stripping ...
