High affinity receptor labeling based on basic leucine zipper domain peptides conjugated with pH-sensitive fluorescent dye: Visualization of AMPA-type glutamate receptor endocytosis in living neurons

Fluorescence Lifetime Imaging of Cancer In Vivo

Optical imaging of fluorescent reporters in animal models of cancer has become a common tool in oncologic research. Fluorescent reporters including fluorescent proteins, organic dyes, and inorganic photonic materials are used in fluorescence spectroscopy, microscopy, and whole body preclinical imaging. Fluorescence lifetime imaging provides additional, quantitative information beyond that of conventional fluorescence intensity signals, enabling signal multiplexing, background separation, and biological sensing unique to fluorescent materials.

A precise pointing nanopipette for single-cell imaging via electroosmotic injection

Schematic illustration of a nanopipette with fluorescent molecules aggregated at the tip which are injected into a single-cell. The nanopipette is backfilled with solution and a Ag/AgCl electrode is inserted, which acts as the working electrode. Another Ag/AgCl electrode is immersed in the bulk solution as the reference electrode.
