Modification of WS2 nanosheets with beta-cyclodextrone and N-isopropylacrylamide polymers for tamoxifen adsorption and investigation of in vitro drug release

Abbas Bohloli et al.

Summary: In this study, WS2/beta CD/NIPAAP samples were synthesized and their adsorption performance towards TAM drug was investigated. The results showed a high maximum adsorption capacity and good reusability. Additionally, the drug release behavior at different temperatures was studied, with the zero-order model providing a good fit for the release data, indicating a case II transport. The TAM drug exhibited high stability in the WS2/beta CD/NIPAAP carrier.

Sensitive electrochemical detection of L-Cysteine at a screen-printed diamond electrode

Tomohiro Matsunaga et al.

Summary: The study found that hydrogen-terminated boron-doped diamond printed electrode was the most suitable for the sensitive detection of L-cysteine at low concentrations, exhibiting a steep slope in its calibration curve and low background current density. This printed electrode had a lower limit of detection and wider linear concentration range compared to a hydrogen-boron-doped diamond thin-film electrode.

Carbon dots-based fluorescence and UV-vis absorption dual-modal sensors for Ag+ and L-cysteine detection

Shan Lu et al.

Summary: The use of fluorescence/UV-Vis absorption dual signaling probes is an effective approach to improve the reliability of carbon dots-based sensors. Orange emissive CDs were utilized as dual-functional probes for selectively detecting Ag+ and L-Cysteine with low detection limits. The CDs demonstrate excellent performance in selectively detecting intracellular changes of Ag+ and L-Cys, making them ideal for potential applications in environmental survey and biological assay.

Fluorescence switch of gold nanoclusters stabilized with bovine serum albumin for efficient and sensitive detection of cysteine and copper ion in mice with Alzheimer 's disease

Yaxin Niu et al.

Summary: The fluorescence enhancement and quenching of gold nanoclusters stabilized with bovine serum albumin (BSA-AuNCs) in response to cysteine and copper ion enables sequential detection of the two molecules. This system shows promise for early diagnosis of Alzheimer's disease, with the ability to detect these biomolecules in mice brain in vitro.

Synergistic effects of SnO2 and Au nanoparticles decorated on WS2 nanosheets for flexible, room-temperature CO gas sensing

Jae-Hun Kim et al.

Summary: In this study, researchers fabricated WS2 nanosheets decorated with different materials on flexible substrates for CO gas sensing. The sensors exhibited unique responses and high selectivity to CO gas, with the Au-SnO2-co-decorated WS2 nanosheet sensor showing the highest response and selectivity. The presence of Au-WS2 Schottky junctions, SnO2-WS2 heterojunctions, and the catalytic role of Au nanoparticles in sensing CO gas were key factors contributing to the sensor's performance.

Fabrication of a sensitive colorimetric nanosensor for determination of cysteine in human serum and urine samples based on magnetic-sulfur, nitrogen graphene quantum dots as a selective platform and Au nanoparticles

Roya Afsharipour et al.

Summary: A novel colorimetric nanosensor was developed for the selective and sensitive determination of cysteine using Fe3O4/S, N-GQDs, and Au NPs. The method showed a linear proportionality with cysteine concentration and a limit of detection of 0.009 mu mol L-1 under optimized conditions. This simple and fast fabrication technique can efficiently quantify ultra traces of cysteine in human serum and urine samples.
