Exploring sustainable synthesis paths: a comprehensive review of environmentally friendly methods for fabricating nanomaterials through green chemistry approaches.

This comprehensive review delves into the burgeoning field of nanotechnology, where the synthesis of nanoparticles (NPs) is strategically tailored to specific applications. Embracing the principles of green chemistry, nanotechnology increasingly utilizes environmentally friendly materials, such as plant extracts or microorganisms, as capping or reducing agents and solvents in the synthesis process. Notably, plant-based synthesis demonstrates enhanced stability and faster rates compared to microorganisms.

Total Synthesis of 6-Hydroxymetatacarboline-d Discovered from via the Pictet-Spengler Reaction Followed by the Horner-Wadsworth-Emmons Reaction.

Total synthesis of a new β-carboline alkaloid, 6-hydroxymetatacarboline-d, which was isolated from fruiting bodies of was accomplished in 14 steps. The synthetic strategy features the Pictet-Spengler reaction to construct the tricyclic core followed by amide coupling and the Horner-Wadsworth-Emmons reaction.

Biogenic Synthesis of Copper and Silver Nanoparticles Using Green Alga and Its Antimicrobial Activity.

The spread of infectious diseases and the increase in the drug resistance among microbes has forced the researchers to synthesize biologically active nanoparticles. Improvement of the ecofriendly procedure for the synthesis of nanoparticles is growing day-by-day in the field of nanobiotechnology. In the present study, we use the extract of green alga for the synthesis of copper and silver nanoparticles.
