Terpyridine/benzofurazan conjugation results in a new hybrid fluorophore of the colorimetric sensing ability for Fe(2+) and fluorimetric sensing ability for XII group cations. The improved emission properties and cell imaging ability imply it is a suitable platform to construct a

We studied the effects of spacer length on the fluorescence quantum yields (Phi) of photoinduced electron transfer (PET) reagents, using nitrobenzoxadiazole (NBD) derivatives that have the -NMe2 moiety and NBD-NH- fluorophore as electron donor (D) and electron acceptor (A), respectively.

A colorimetric sensor array composed of seven molecularly imprinted polymers was shown to accurately identify seven different aromatic amines. The response patterns were systematically classified using linear discriminant analysis with 94% classification accuracy. Analyses of the response patterns of the

One of the most common mechanisms of hepatotoxicity is drug-induced cholestasis. Hence, new approaches for screening the cholestatic potential of drug candidates are desirable. In this context, we describe herein the use of synthetic 4-nitrobenzo-2-oxa-1,3-diazole (NBD) fluorescent conjugates of cholic

The superoxide (O2-.) production in Escherichia coli through the action of benzofurazans (BZs) was examined using the cytochrome c (cyt. c) reduction method. Adding BZs to E. coli cell suspensions caused the cyt. c reduction, which was completely inhibited by
