A highly sensitive, selective, and dual-readout (colorimetric and fluorometric) assay for acetylcholinesterase (AChE) based on Rhodamine B-modified gold nanoparticle is reported. Due to its good sensitivity and selectivity, the assay can be used for monitoring AChE levels in the cerebrospinal fluid of transgenic mice with Alzheimer's disease.
Economical nanocomposites based on π-stacking of N-acetyl glycosyl rhodamine B to graphene oxide (GO) are simply prepared. These "sweet" GO-materials are proven to be admirable for the fluorogenic recognition of specific intercellular sugar-based ligand-glycoprotein receptor interactions of interest.
Visible-light-induced electron transfer from a tungstate to a titanate layer was demonstrated to be mediated by excited rhodamine B (RhB) intercalated by ion exchange between the two layers. The distance of only 1 nm between the layers provides a large contact area that enables the efficient mediation of electron transfer by RhB.
