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

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

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

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.

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
