Summary: Simple Walled Carbon Nanotubes (SWCNTs) were used as adsorbents to remove triclosan (TCS) from aqueous solution. The maximum adsorption capacity of TCS onto SWCNTs was found to be 30.3 mg g(-1) at a pH value of 7. The adsorption kinetics of TCS on SWCNTs was correctly interpreted by the First Order Kinetic Model and the Diffusional Model.

Summary: In this study, the plasmonic effects of Ag and Au nanoparticles with different geometries on the fluorescence intensity of single-stranded DNA-wrapped single-walled carbon nanotubes (ssDNA-SWCNTs) were systematically investigated. Chirality-dependent fluorescence enhancement was observed, which varied with nanoparticle shape and material. Au nanorods increased the fluorescence of (7, 5) and (7, 6) chiralities by 80% and 60% respectively, while Ag nano triangles increased the fluorescence of (7, 5) and (6, 5) chiralities by 200% and 240% respectively. Finite element modeling confirmed contributions from a plasmon-induced localized increase in electron density and radiative recombination of dark exciton states from the resulting electromagnetic field.

Summary: The probability of occupational exposure to carbon nanotubes (CNTs) is increasing due to their growing production and biomedical applications. As a result, the risk of co-exposure of nanomaterials with environmental pollutants is also increasing. This study investigated the toxicity of pristine single-walled CNTs (p-SWCNTs) and oxidized single-walled CNTs (SWCNT-COOHs) on cell responses to metal ions (Pb2+, Cu2+, and Cr(VI)). The findings suggest that understanding the effects of the exposure sequence of engineered nanomaterials and environmental pollutants on their toxicity is crucial for evaluating combined toxicity.

Summary: Thermal conductivity of a suspended single-walled carbon nanotube (SWCNT) is significantly enhanced by introducing an axial tensile strain, and the enhancement is positively correlated with the strain magnitude. Furthermore, the reduction of thermal conductivity with temperature is alleviated for the strained nanotube compared to unstrained cases.

Summary: Matrix metalloproteinases (MMPs) are attractive biomarkers for cancer diagnosis and treatment, but their low abundance in biological samples, especially in the early stages of tumors, makes it challenging to precisely analyze MMP activities. In this study, a peptide microarray-based metal-enhanced fluorescence assay (PMMEFA) is proposed as a sensitive and specific method to simultaneously detect MMP-1, -2, -3, -7, -9, and -13 activities. The PMMEFA showed excellent sensitivity and was capable of detecting MMP activities in various matrices.
