Light-driven hydrogen production catalysed by transition metal complexes in homogeneous systems

Abstract: The development of heterogeneous catalytic systems for hydrogen production from water under light irradiation has been investigated during last three decades Homogeneous photocatalysts, however, are very attractive in sense that their chemical and photochemical properties can be understood and tuned on molecular level Moreover, in homogeneous systems catalysts may be covalently bound to photosensitizers, which leads to more efficient electron transfer Molecular devices for water splitting based on such a systems are of great interest In this review, we summarize recent progresses in the synthesis, properties and application of metal-based molecular catalysts for photoinduced hydrogen evolution in homogeneous systems

Fluorescent Nanosensors Based on Fluorescence Resonance Energy Transfer (FRET)

Abstract: Fluorescence resonance energy transfer (FRET) has been widely used as a spectroscopic technique in various areas such as structural elucidation of biological molecules and their interactions, in vitro assays, in vivo monitoring in cellular research, nucleic acid analysis, signal transduction, light harvesting, and metallic nanomaterials. Meanwhile, based on the mechanism of FRET, a series of FRET nanomaterials systems have been recently developed as novel chemical sensors and biosensors. Compared with those based on small molecules traditional FRET systems, the surface chemistry of nanomaterial has encouraged the development of multiple probes based on linked recognition molecules such as peptides, nucleic acids, or small-molecule ligands. This critical review highlights the design and the applications of sensitive and selective ratiometric nanoprobes based on FRET. We focus on the benefits and limitations of nano-FRET systems and their applications as chemical sensors and biosensors.
