Green synthesis and evaluation of antiangiogenic, photocatalytic, and electrochemical activities of BiVO4 nanoparticles

Nanocrystalline bismuth vanadate has been steadily gaining attention in recent years due to its potential energy conversion and eco-friendly nature. Herein, we report the green synthesis of bismuth vanadate nanoparticles (BVNPs) using jackfruit extract as a fuel and its characterization using various analytical and/or spectroscopic techniques for the assessment of physicochemical and structural properties. Further, bismuth vanadate nanoparticles were characterized by P-XRD, SEM, HRTEM, FTIR, EDX, Raman spectroscopy, and photoluminescence spectroscopy (PL). Pharmaceutical and personal care products being used and their accumulation in various water bodies are raising concern among the public health. As a part of our study, synthesized bismuth vanadate nanoparticles were subjected to photocatalytic activity due to their high separation rate of photodegraded charge carriers leading to degradation up to 98.3% under visible light irradiation for 120 min. A feasible mechanism of photodegradation has been explained by considering methylene blue dye as a model organic pollutant. Further, bismuth compounds has been used extensively as medicines in various treatments, and therefore, bismuth vanadate nanoparticles were subjected for cell viability test against MCF-7 breast cancer cell lines using trypan blue and MTT assays. In continuation, the synthesized bismuth vanadate nanoparticles were shown to have antiangiogenic property confirmed by shell-less CAM assay. The electrochemical properties of BVNPs have been studied by using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), and these results depict BVNPs could be used as super capacitors and bio-sensing material. The present work provides beneficial data set for the green synthesis of nanoparticles and environmental and clinical applications.
