Biocompatible Nanoarchitectonics of Water‐Soluble Vanadium Dichalcogenides Quantum Dots Functionalized with Capping Agents

Abstract

Herein, three different water‐soluble functional groups capped vanadium disulfide quantum dots (VS2QDs), namely, L‐cysteine capped VS2QDs (L‐cys‐VS2QDs), thioglycolic acid capped VS2QDs (TGA‐VS2QDs), and 3‐mercaptopropionic acid capped VS2QDs (MPA‐VS2QDs) are synthesized via hydrothermal method. The comparison of the biocompatibility (MTT assay) of three differently capped VS2QDs is performed in RAW cell 264.7 cells with different concentrations (500, 250, 125, 62.5, 15.625, 7.812, and 3.906 μg mL−1). It is found that L‐cys‐VS2QDs show more biocompatibility than the TGA‐VS2QDs and MPA‐VS2QDs. However, at low concentrations, TGA‐VS2QDs also show better biocompatibility, whereas MPA‐VS2QDs show the least biocompatibility. Biocompatibility of L‐cys‐VS2QDs is also almost consistent with entire range of QDs concentrations may be due to L‐cys cellular inflammation and maintaining pH buffer.

Room temperature multiferroic nanostructured Gallium Ferrite based visible light driven photocatalyst for degradation of azine dyes

“…Surface states and defects distributed due to the high surface-to-volume ratio contribute to additional energy levels, further broadening the spectrum. (Kumar et al 2023a andKumar et al 2023b) Also, multiple electronic transitions, crystal eld effects, and charge transfer processes in GFOnps contribute to the overall spectrum broadening. Thus, a broad absorption spectrum is obtained in UV-Vis study.…”

“…This is related to the synthesis technique, as well as morphology of the material including using capping agents as well as composites. (Kumar et al 2023a and Kumar et al 2023b) Gallium ferrite (GFO) nanoparticles synthesized using the low-temperature sol-gel method, nd diverse applications across several elds. The low-temperature solgel synthesis method offers several distinct advantages when producing gallium ferrite (GFO) nanoparticles.…”
