Nanomaterials have received much attention because their structure and properties differ significantly from those of atoms, molecules and bulk materials [1]. The synthesis of metal nanoparticles has been widely discussed in the literature due to their unique physical and chemical properties, which have many potential applications. [2–4] The use of inexpensive chemicals and non-toxic solvents – environmentally friendly and renewable/biodegradable – is essential for the synthesis and processing of materials, given the green nature of these strategies. Over the past decade, green nanoparticle synthesis has become an important branch of nanotechnology due to its potential application in the biomedical, magnet, energy science, and aerospace industries. Large quantities of nanoparticles can be easily synthesized from plants and the majority of them are non-toxic. [5-8] They have been used in pharmaceutical industries to treat B chronic lymphocytic leukemia, to detect DNA, to inhibit bacteria and fungi, and to prevent burns and open wound infections. [9–12] Several techniques, such as chemical, electrochemical, radiological, photochemical, and biological, have been used for the biosynthesis of silver and gold nanoparticles.

Rapid technological advancements have led to the expansion of nanoscale device components, advanced sensors, and new biomimetic materials.[16-18] Among noble metals, silver nanoparticles have received considerable attention in due to their attractive physicochemical properties, such as magnetic and optical polarizability. , electrical conductivity, catalysis, antimicrobial behavior, DNA sequencing, surface enhanced Raman scattering and thermal properties.[18-20] Silver nanoparticles have been shown to have strong antimicrobial activity and are used in wound dressings, contraceptive devices and surgical instruments. , bone prostheses and as a coating for eye lenses to prevent microbial activity.[21-23] However, the potentially negative impacts of nanomaterials are sometimes overlooked during the discovery phase of research. Implementing green chemistry principles can improve nanoscience by maximizing safety and efficiency while minimizing the environmental and societal impacts of these materials. Using plant extracts for nanoparticle synthesis can be advantageous over other biological processes because it eliminates the complex process of maintaining cell cultures and can also be scaled up for nanoparticle synthesis on a large scale.[24] In this present report, we have developed a simple one-step green chemistry approach for theKeep in mind: this is just a sample.Get a custom paper now from our expert writers.Get a custom essaySynthesis of colloidal silver nanoparticles using Aloe vera extract, it acts as a reducing agent as well as a stabilizing/capping agent in the synthesis of nanoparticles (25), (ii) Aloe Vera is an important useful medicinal plant for the treatment of several diseases such as anticancer drugs (26-28), antibacterial drugs (29), headaches (30), and..
