Biosynthetic trends and future aspects of bimetallic nanoparticles and its medicinal applications

Abstract

Recently, in all over the world, nanotechnology plays a major role in various applications. Most of the researchers focused their work on bimetallic nanoparticles due to their several modes or mechanisms of synthesis such as chemical, physical, and biosynthesis methods. These nanoparticles are of great interest due to their enormous applications and catalytic activities. Currently, syntheses of bimetallic nanoparticles using different sources of natural products are focused due to their advantage of being nontoxic to human and environment. To our knowledge, there is no report on the review of bimetallic nanoparticles and their medicinal applications. Taking this fact into account, we discussed the various synthesizing methods of bimetallic nanoparticles and their application related to biology.

Characterization of green synthesized nano-formulation (ZnO–A. vera) and their antibacterial activity against pathogens

“…The addition of A. vera to ZnO could result to local shifts in the interconnected grains, thereby reducing internal stresses. Generally, the oxide product exhibit relative good incorporation of A. vera extracts, with an observed well-defined and easily accessible crystal surface (Jalal et al, 2010;Roopan et al, 2014).…”

“…6 shows the transmittance of ZnO NPs and ZnO + A. vera nanocomposites. The diffuse transmittance increased to 89% (ZnO) and 45% (ZnO + A. vera) in the visible region, which could be due to the increase in surface states of Zn ions and the decrease in surface defects (Roopan et al, 2014).…”

Characterization and Antimicrobial Activity of ECO-Friendly Biosynthesis of Silver Nano Particles Using An Aqueous Leaf Extract of Catharanthus Roseus

“…In the emerging field of nanotechnology, the formation of nanoparticles using biological materials as reducing agents is receiving more attention, especially in the last decade [13]. Successful biosynthesis of AgNPs by the filtrate of C. roseus was confirmed by the change in the color of the filtrate from yellow to dark brown after the addition of AgNO 3 but control flasks, containing only the AgNO 3 solution (without plant filtrates) did not show any color change.…”

Preparation, characterization, molecular docking and in vitro evaluation of two novel morin hydrate/CD inclusion complexes

“…Currently, a variety of formulations, exemplified by amorphous solids, co-solvent addition, water-soluble complexes and nanoparticles have been utilized to promote the water solubility of medicinal components that are poorly dissolved in water [11][12][13]. In addition to these extensively studied methods to improve solubility and bioavailability, the molecular encapsulation with cyclodextrin is also an effective and useful technique.…”
