Advanced sensing technologies of phenolic compounds for pharmaceutical and biomedical analysis
Phenolic compounds are bioactive natural products of considerable interest in pharmaceuticals and biomedicines. Due to their bioactive functions, phenolic compounds have received increasing attention in recent years. Therefore, it is necessary to develop new and advanced analytical methods for determination of phenolic compounds in relation to pharmaceutical and biomedical applications. However, in majority, their detection has been largely conducted by sensitive yet bulky and expensive laboratory instruments, such as gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry. Compared with those laboratory scale instruments, the advanced sensing technologies are extremely attractive due to the advantages of their low cost, time saving, user-friendly, simplified sample pre-treatment, high sensitivity, and excellent selectivity. The aim of this review is to provide critical information on the advanced sensing technologies for detecting phenolic compounds, with emphasis on optical sensors, electrochemical sensors and biosensors. Besides, the present status, critical issues and future trends of the related sensing technologies are outlined.National Environmental Agency (NEA)This work was supported by the National Environment Agency (NEA) of Singapore under the Urban Solutions and Sustainability (USS) Integration Fund

Catalytic Oxidation of Carbon Monoxide over Transition Metal Oxides
International audienceOxidation into CO2 is a major solution to CO abatement in air depollution treatments. The development of catalytic converters led to an extraordinary high number of publications on metal catalysts during the last fifty years. Due to the increasing price of noble metals and to remarkable progresses in oxide syntheses, catalytic oxidation of carbon monoxide over oxide catalysts has recently gained in interest, even if some oxides are known to present remarkable activity since the beginning of the 20th century. In this Review, the kinetics and mechanism of CO oxidation on single and mixed oxides are examined, alongside the catalyst structure
