Regioselective oxidation of indole- and quinolinecarboxylic acids by cytochrome P450 CYP199A2.

Appl. Microbiol. Biotechnol. 85(6) , 1861-8, (2010)

CYP199A2, a bacterial P450 monooxygenase from Rhodopseudomonas palustris, was previously reported to oxidize 2-naphthoic acid and 4-ethylbenzoic acid. In this study, we examined the substrate specific...

A new analytical method to determine non-steroidal anti-inflammatory drugs in surface water using in situ derivatization combined with ultrasound-assisted emulsification microextraction followed by gas chromatography-mass spectrometry.

Talanta 129 , 552-9, (2014)

Because of the high stability and potential toxic effects of non-steroidal anti-inflammatory drugs (NSAIDs), it is important to closely monitor their concentrations in the environment using a sensitiv...

Beta-cyclodextrin decorated nanostructured SERS substrates facilitate selective detection of endocrine disruptor chemicals.

Biosens. Bioelectron. 42 , 632-9, (2013)

We demonstrate the selective detection of endocrine disruptor chemicals (EDCs) from river water using surface enhanced Raman scattering (SERS). By means of nanosphere lithography, the SERS substrate w...
