Designing the selectivity of the fluorescent detection of amino acids: A chemosensing ensemble for histidine

The imidazole group of histidine deprotonates and bridges the two CuII centers of a dimetallic polyamine macrocyclic complex, displacing the previously bound and quenched fluorescent indicator I. Thus, histidine recognition is signaled by the revival of the fluorescence of I. Selectivity with respect to other natural amino acids is achieved by choosing an indicator of tuned affinity toward the dicopper(II) receptor. Copyright
A Kinetic Study on the Electrochemical Bromination of Fluorescein to Eosin in a Batch Reactor
Vasudevan, D.,Basha, C. A.
, p. 165 - 166 (2007/10/03)
The bromination of fluorescein to eosin has been carried out in a batch reactor in NaHCO3 medium using TSI anode, stainless steel cathode and nylon as the separator. The kinetics of the reaction have been followed by uv-visible spectra of samples withdrawn at various time intervals during the electrolysis. Probable mechanism for the bromination of fluorescein has been suggested and attempts have been made for reaction modeling.
