We evaluate the application of surfactant-free liquid-phase exfoliated MoS2 nanosheets as a nanoplatform for a cancer detection and treatment system equipped with an antibody-antigen based recognition element. Employing antigen-antibody binding, we increased the probability of the endocytosis of MoS2 nanosheets into CAIX expressing cells by 30%. The nanosheets are functionalized with a specific antibody M75, which forms an antigen-antibody complex with CAIX. The bioconjugation of MoS2 nanosheets involves biocompatible components with low cytotoxicity, verified in the tested cell lines by fluorescence-based cell viability assay. The cellular internalization is quantified by flow cytometry, while the internalization is confirmed by label-free confocal Raman imaging. Raman measurements show increased lysosomal activity in the proximity of the internalized nanoplatforms.

Understanding the behavior and fate of microplastics (MPs) in aquatic environment is crucial for assessing their potential risks. This study investigated the heteroaggregation behaviors of MPs with representative 2D nanosheets, MoS and graphene oxide (GO), under various conditions, focusing on the transport behavior of the resulting aggregates. It was found that the destabilization capabilities of 2D nanosheets are notably stronger than those of well-reported nanoparticles.

During fast-charging, uneven lithium plating on the surface of commercial graphite anode impedes the electrochemical performance of lithium-ion batteries, causing a safety issue. The formation of a passivation layer, the solid-electrolyte interphase (SEI), due to side reactions with the organic electrolyte, correlates with long-term cycling performance under fast-charging conditions, necessitating comprehensive analysis. Herein, it is demonstrated that a molybdenum disulfide (MoS) coating on natural graphite (NG) modulates the properties of the SEI layer, enabling reduction of the charging time and the enhancement of long-term cycling performance.

Photocatalytic removal of antibiotic such as ciprofloxacin from polluted water is of great value for eco-environment protection. To further enhance the piezoelectric effect in photocatalysis, we designed and synthesized a ternary heterojunction piezoelectric photocatalyst through uniformly loading MoS nanosheets onto BiFeO (BFO) nanofibers, namely MoS/BiS/BFO. Piezoresponse force microscopy and Kelvin probe force microscopy demonstrated its enhanced piezoelectric properties, showing a maximum amplitude displacement of 395.
