Abstract
It is essential to recognize efficient heterogeneous catalysts for environmental remediation that can eliminate organic contaminants or transform them into beneficial byproducts. Herein, we have designed and developed a gold nanoparticle based green nanocomposite material templated over the Curcuma longa extract. The Au NPs/C. longa nanomaterial was thoroughly characterized by FT-IR and UV–Vis spectroscopy followed by FE-SEM, EDX, TEM and XRD analysis. Subsequently, towards the wastewater treatment, it demonstrated excellent potential in the reduction of water contaminant toxic organic dyes like methylene blue (MB), methyl orange (MO), and 4-nitrophenol (4-NP) following excellent kinetics, as monitored by UV–Vis spectrophotometer. The reaction followed a pseudo-first order kinetics. The robustness of the nanocatalyst was justified by reusability studies, and hot filtration test and the catalytic activity did not substantially decline over the course of seven cycles. Towards the assessment of biological activity of Au NPs/C. longa nanocomposite antioxidant capacity was evaluated first using the DPPH radical scavenging method. Further, the study was extended in the investigation of anti-lung cancer properties against a number of standard lung cancer cell lines, viz., NCI-H661, NCI-H1975, NCI-H1573, and NCI-H1563 following MTT colorimetric in vitro studies. Curcuma longa-modified Au NPs are thought to have potential biological activities because of their exceptional capacity to produce reactive oxygen species (ROS).
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
