Fluorescent tracer dyes represent an important class of sub-cellular probes and allow the examination of cellular processes in real-time with minimal impact upon these processes. Such tracer dyes are becoming increasingly used for the examination of membrane transport processes, as they are easy-to-use, cost effective probe substrates for a number of membrane protein transporters. Rhodamine 123...

ess as: P r visibl niversity 2013.11.0 Abstract In this study, laponite and montmorillonite clays were found to be able to decompose rhodamine B upon visible light irradiation (k > 420 nm). Very interestingly, it was found that rhodamine B on laponite underwent a stepwise N-deethylation and its decomposition was terminated once rhodamine 110, as a decomposition product, was formed, whereas the ...

Fluorescence microscopy of the localization and the spatial and temporal dynamics of specifically labelled proteins is an indispensable tool in cell biology. Besides fluorescent proteins as tags, tag-mediated labelling utilizing self-labelling proteins as the SNAP-, CLIP-, or the Halo-tag are widely used, flexible labelling systems relying on exogenously supplied fluorophores. Unfortunately, la...

A new simple, fast, and versatile method is developed to functionalize gold nanoparticles (AuNPs) via nanoscale layers of molecularly imprinted polymers (MIPs). The key step based on near-field radical photopolymerization the MIP prepolymerization mixture. This enables fabrication [email protected] hybrid nanoparticles, which are used as substrates for localized surface plasmon resonance surfac...

Highly water soluble fluorescent dyes were synthesized and transformed into new amino reactive fluorescent labels for biological microscopy. To this end, rhodamine 8 (prepared from 7-hydroxy-1,2,3,4-tetrahydroquinoline (7) and phthalic anhydride in 85 % aq. H(3)PO(4)) was sulfonated with 30 % SO(3) in H(2)SO(4) and afforded the water soluble disulfonic acid 3 a (64 %). Amidation of the carboxy ...

The heating of microfluidic channels such as occurs in cell stretching and sorting devices was examined using the established technique of recording the intensity ratio between two fluorescent dyes, Rhodamine B (RhB) which is temperature sensitive and Rhodamine 110 (Rh110) which is not[1]. Microfluidic devices each consisting of a single channel and waveguide input were manufactured using ultra...

Zheng has proposed a seller-optimal auction for (asymmetric) independent-privatevalue environments where inter-bidder resale is possible. Zheng’s construction requires novel conditions—Resale Monotonicity, Transitivity, and Invariance—on the bidders’ value distribution profile. The only known examples of distribution profiles satisfying these conditions in environments with three or more bidder...
