Determination of iron in chinese herbal medicine based on the fluorescence quenching of rhodamine 6G
Bulletin of the Chemical Society of Ethiopia, 2009 A fluorescence quenching method was developed for determination of Fe3+ with rhodamine 6G as fluorescent reagent. Fe3+ reacting with KI in diluted sulfuric acid produced I3- anion which reacted subsequently with rhodamine 6G to form a non-fluorescence ...

Novel diatom-FeOx composite as highly active catalyst in photodegradation of Rhodamine-6G
Nanotechnology Reviews, 2018 We report the study of nanoporous silica-iron oxide composite generated from diatom frustules as a highly active catalyst for the photodegradation of the dye Rhodamine-6G.

Study of excitation transfer in laser dye mixtures by direct measurement of fluorescence lifetime [PDF]
By directly measuring the donor fluorescence lifetime as a function of acceptor concentration in the laser dye mixture Rhodamine 6G-Cresyl violet, we found that the Stern-Volmer relation is obeyed, from which the rate of excitation transfer is determined.

Trapping of Rhodamine 6G excitation energy on cellulose microparticles
Physical Chemistry Chemical Physics, 2010 Rhodamine 6G (R6G) was adsorbed on cellulose microparticles and fluorescence quantum yields and decays were measured as a function of dye loading. Though no spectroscopic evidence of dye aggregation was found, a noticeable decrease of quantum yield--after correction for reabsorption and reemission of fluorescence--and shortening of decays were observed

Advanced Science, EarlyView.ABSTRACT Colorectal cancer (CRC) remains therapeutically challenging due to high metastasis, recurrence, and immunotherapy resistance driven by tumor microenvironment‐mediated immune evasion. Immunogenic cell death (ICD) offers a promising strategy to reshape the immune microenvironment, yet existing ICD inducers suffer from poor targeting efficiency ...

BMEMat, EarlyView.This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.
