We report two-photon fluorescence microscopy (2PFM) imaging and in vitro cell viability of a new, efficient, lysosome-selective system based on a two-photon absorbing (2PA) fluorescent probe (I) encapsulated in Pluronic® F-127 micelles. Preparation of dye I was accomplished via microwave-assisted synthesis, resulting in improved yields and reduced reaction times. Photophysical characterization revealed notable 2PA efficiency of this probe.

A novel type of self-fluorescent unimolecular micelle nanoparticle (NP) formed by multi-arm star amphiphilic block copolymer, Boltron(®) H40 (H40, a 4th generation hyperbranched polymer)-biodegradabl...
Accurate energy calibration is critical for the application of energy-resolved photon-counting detectors in spectral imaging. The aim of this study is to investigate the feasibility of energy response...
Two novel water-soluble coumarin-based compounds (OC7, NC7) were designed and synthesized as two-photon fluorescent probes for biological Mg2+ detection. The compounds feature a beta-keto acid as a hi...
Three rationally designed polar derivatives of diketopyrrolopyrrole consisting of 1,3-dimethylimidazolium cationic units and benzene, thiophene, or furan rings as π spacers were synthesized and thoro...
A polymer and silica co-protection strategy has been developed to encapsulate organic fluorogens with aggregation-induced emission and charge transfer characteristics into small nanoparticles (NPs). T...
To improve rectal cancer management, there is a need for better visualization of drug targets in rectal cancer to identify patients who might benefit from specific targeted treatments. Mol...
RATIONALE: Drugs used in chemotherapy, such as paclitaxel-loaded polymeric micelle and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or...
The purpose of this study is to evaluate the response rate in patients with taxane-pretreated recurrent breast cancer receiving paclitaxel loaded polymeric micelle (Genexol-PM).
The purpose of this study is to identify genetic, biochemical, and clinical factors that are associated with disease severity in people with Gaucher disease and other lysosomal storage dis...
Breast cancer is the most commonly occurring cancer in women. Currently, breast conservation surgery (BCS) is the treatment most often prescribed. BCS involves removing the tumor while con...
Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilizes antibodies that are labeled with fluorescent dye.
A type of FLUORESCENCE SPECTROSCOPY using two FLUORESCENT DYES with overlapping emission and absorption spectra, which is used to indicate proximity of labeled molecules. This technique is useful for studying interactions of molecules and PROTEIN FOLDING.
Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
A type of IN SITU HYBRIDIZATION in which target sequences are stained with fluorescent dye so their location and size can be determined using fluorescence microscopy. This staining is sufficiently distinct that the hybridization signal can be seen both in metaphase spreads and in interphase nuclei.
Protein analogs and derivatives of the Aequorea victoria green fluorescent protein that emit light (FLUORESCENCE) when excited with ULTRAVIOLET RAYS. They are used in REPORTER GENES in doing GENETIC TECHNIQUES. Numerous mutants have been made to emit other colors or be sensitive to pH.
