Researchers from India have shared an eco-friendly method for the fabrication of metal nanoparticles in their latest article available as a pre-proof in the journal Environmental Nanotechnology, Monitoring & Management.
Importance of Metal Nanoparticles
Metal nanoparticles in simple words could be defined as nanoscale derivatives of pure metals such as gold, thallium, and silver, or their compounds. Metallic nanoparticles (MNPs) feature a metal core formed of synthetic metal or metal oxide that is generally surrounded by an organic or inorganic substance or metal oxide shell.
The production of noble metallic nanoparticles has evolved into an enthralling process of scientific study. Because of their exceptional toxicological and photonic characteristics, silver and gold nanoparticles have received a great deal of attention, opening the way for extraordinary applicability in electromagnetic, semiconductors, photonics, biomedical, biosensing, catalytic, and medicinal domains.
Preparation Methods
Metal nanoparticles are often produced by reducing matching metal salt solutions with reduction enhancing substances such as sodium borohydride and citrate under severe experimental parameters. Furthermore, encapsulating entities are required, with amine or thiol-containing organic ligands and other surfactants being used to create these nanoparticles.
Previously, phyto-mediated reduction processes employing plant extracts have been used in the manufacture of metal nanoparticles to fulfill the green standard in reactions by avoiding hazardous chemicals.
Despite significant progress in the manufacture and usage of MNPs across the world, there is still a significant gap in information about the toxicity-related consequences of these on health and the environment.
Why Carbon Dots (CDs) are Important?
Carbon dots (CDs), a recent addition to the nano-carbon family distinguished by carbon nucleus related functional group, possesses exceptional biochemical and optoelectronic properties features such as adjustable fluorescence, high water dispersion, low cytotoxicity, and excellent stability.
C-dots are a novel type of luminous small-carbon nanocomposites with particle sizes less than 10 nm. Because of these characteristics, they have emerged as attractive candidates in detection, catalyst supports, bio-imaging, illumination, biomedical applications, and other domains.
Future research will focus on the creation of various morphologies, dimensions, and target-specific carbon dots. The synthetic paths to CDs, like any other nanomaterial, are loosely classed as top-down and bottom-up processes.
Greener Methods of Carbon Dot Synthesis
A great deal of attention has been dedicated to the implementation of green solutions for manufacturing CDs from affordable environmental assets in a greener and environmentally friendly manner.
Plant sources such as peppermint, coriander, banana peel, lemon, and others have been used as an alternative to synthetic antecedents in the manufacture of carbon nanodots.
CDs have recently been found for their reducing nature as well. Despite the fact that CDs have been discovered as a sustainable reduction tool for noble metal nanoparticles production via environmental initiatives, this topic is still in its infancy.
In the present study, carbon dots generated from the foliage of organic herbs, Plectranthus amboinicus (PA-CDs) and Leucas lavandulifolia (LA-CDs), have shown excellent reduction status.
