Formulation of bactericidal cold cream against clinical pathogens using Cassia auriculata flower extract-synthesized Ag nanoparticles

Abstract

A simple formulation of bactericidal cold cream using the biosynthesized silver nanoparticles (AgNPs) from Cassia auriculata flower extract and their antibacterial activity was tested against various clinical pathogens such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Staphylococcus epidermidis. An ecofriendly method was followed for the biosynthesis of AgNPs using C. auriculata flower extract as a reducing agent at room temperature. The effect of different concentrations of flower extract and the various pH conditions of the reaction medium toward the formation of NPs were studied. Surface plasmon resonance peaks were obtained from 403 nm to 428 nm. Further, the synthesized NPs were characterized by dynamic light scattering particle size analysis, Zeta potential analysis, atomic force microscope, and high-resolution transmission electron microscopic analysis.

Biochemical Evaluation and Green Synthesis of Nano Silver Using Peroxidase fromEuphorbia(Euphorbia amygdaloides) and Its Antibacterial Activity

“…Some studies have been made for the production of nanoparticles by using plant extracts: Achillea biebersteinii [10], Cassia auriculata [11], Acacia farnesiana [12], Gloriosa superba [13], Alternanthera dentata [14], Cocos nucifera [15], and so forth. However very few studies were found for synthesis of nanoparticles by using peroxidase enzyme.…”

Cytogenetic effects of silver and gold nanoparticles on Allium cepa roots

“…Nanotechnology, is special branch of material science where bulk materials break down to small particles within the range of 1–100 nm in diameter by means of physical, chemical and biological methods. Nanotechnology is absolutely a new emerging field, and basically there are evidences of several negative effects on growth and development of plantlets [16] but due to its diverse application in various fields such as DNA sequencing, pharmaceuticals, cosmetics, agriculture, biomolecular detection and diagnostics [17], it has gained attention and synthesized and used extensively in various field. Research has shown both silver and gold nanoparticles can be synthesized easily has many applications which makes it easily accessible and quite popular among researchers.…”

Green biosynthesis and characterization of zinc oxide nanoparticles usingCorymbia citriodoraleaf extract and their photocatalytic activity

“…However, those methods always involve utilization of toxic reagents and expensive instruments along with the tedious process control. Therefore, there is great demand for developing a simple and green method for synthesizing ZnO NPs (19,20). Recently, biosynthesis of NPs was attracted considerable attention due to its simplicity, low cost and nontoxicity.…”
