Three novel camphor-based fluorescence probes for ratiometric detection of hypochlorite and bio-imaging in living cells

Sensors and actuators. B, Chemical, 2019
The development of reliable method for detection of hypochlorite (ClO−) in vivo is of great importance to understand the precise roles of ClO− in a variety of pathological and physiological processes. Herein, three novel camphor-based fluorescence probes

Rational design of NIR fluorescence probes for sensitive detection of viscosity in living cells.

Spectrochimica Acta Part A - Molecular and Biomolecular Spectroscopy, 2019
Developing near-infrared (NIR) fluorescence probes for detection of intracellular viscosity is still sufficiently challenging. In this work, three kinds of D-A-D type naphthyl and 2,1,3‑benzoxadiazol hybrid NIR dyes functionalized with amino (NY1), N ...

Activatable Molecular Probes for Second Near-Infrared Fluorescence, Chemiluminescence, and Photoacoustic Imaging.

Angewandte Chemie, 2020
Optical imaging plays a crucial role in biomedicine. However, due to strong light scattering and autofluorescence in biological tissue ranging 650-900 nm, conventional optical imaging often has poor signal-to-background ratio and shallow penetration ...

Amphiphilic Graphene Quantum Dots as Self‐Targeted Fluorescence Probes for Cell Nucleus Imaging

Advanced Biosystems, 2018
Herein, a one‐step solvothermal strategy to synthesize amphiphilic, highly fluorescent graphene quantum dots (GQDs) as nucleus‐targeted fluorescence probes is reported. The edge‐functionalization of GQDs with N and Cl ligands renders them amphiphilic and

Fluorescent probes in membrane studies

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1972
Abstract A number of spectroscopic techniques are suitable for studying biological membranes. Of these, fluorescence has the sensitivity and time resolution for following membrane events associated with nerve excitation. In this paper, the nature of the information derived from measurements of the fluorescence properties of externally

Removal of binary Cr(VI) and Cd(II) from the catholyte of MFCs and determining their fate in EAB using fluorescence probes.

Bioelectrochemistry, 2018
Electrochemically active bacteria (EAB) on the cathodes of microbial fuel cells (MFCs) can remove metals from the catholyte, but the fate of metals in the cells has not been examined in the presence of multiple metals.
