In this study, the cholic acid-capped gold nanoclusters (CC-AuNCs) were prepared via a microwave-assisted approach and were used as a novel fluorescence probe for detection of creatinine. The CC-AuNCs in solution can emit strong green fluorescence under UV light and the fluorescence intensity can increase with creatinine concentration in the solution because of the aggregation of CC-AuNCs. On the basis of these facts, the fluorescence assay for creatinine was developed. The linear working range is [Formula: see text]–[Formula: see text][Formula: see text]M with a detection limit of [Formula: see text][Formula: see text]M according to signal/noise ratio of 3:1. This fluorescence assay for creatinine has a low detection limit, wide linear range and good selectivity. Furthermore, it can be successfully applied to the detection of creatinine in human urine and serum samples. Thus, this CC-AuNC-based fluorescence assay for creatinine might be of great importance in early diagnosis and therapy of kidney disease.

A facile one-pot microwave-assisted hydrothermal synthesis of rutile TiO2 quadrangular prisms with dominant {110} facets, anatase TiO2 nanorods and square nanoprisms with co-exposed {101}/[111] facets, anatase TiO2 nanorhombuses with co-exposed {101}/{010} facets, and anatase TiO2 nanospindles with dominant {010} facets were reported through the use of exfoliated porous metatitanic acid nanosheets as a precursor. The nanostructures and the formation reaction mechanism of the obtained rutile and anatase TiO2 nanocrystals from the delaminated nanosheets were investigated. The transformation from the exfoliated metatitanic nanosheets with distorted hexagonal cavities to TiO2 nanocrystals involved a dissolution reaction of the nanosheets, nucleation of the primary [TiO6]8− monomers, and the growth of rutile-type and anatase-type TiO2 nuclei during the microwave-assisted hydrothermal reaction. In addition, the photocatalytic activities of the as-prepared anatase nanocrystals were evaluated through the photocatalytic degradation of typical carcinogenic and mutagenic methyl orange (MO) under UV-light irradiation at a normal temperature and pressure. Furthermore, the dye-sensitized solar cell (DSSC) performance of the synthesized anatase TiO2 nanocrystals with various morphologies and crystal facets was also characterized. The {101}/[111]-faceted pH2.5-T175 nanocrystal showed the highest photocatalytic and photovoltaic performance compared to the other TiO2 samples, which could be attributed mainly to its minimum particle size and maximum specific surface area.
