In situ green synthesis of lysozyme/silver nanoparticles sol and their antimicrobial properties

Abstract

Silver nanoparticles (AgNPs) have been widely considered an ideal antimicrobial material due to their superior efficacy. However, it is prone to introduce toxic chemical reductants and stabilizers in the preparation...

Synthesis of Silver Nanoparticles Using Lysozyme for Scald-Wound Healing

“…The protein and Ag + ions were mixed, they quickly combined, and specific amino acid residues in the protein reduced the captured silver ions under visible-light illumination to form metallic silver. Previous reports have shown that light accelerates electron loss, metal species reduction, and nanoparticle formation . This may be one of the reasons why xenon lamp irradiation promotes the formation of AgNPs, and its specific mechanism needs a further study.…”

“…Several previous studies have been conducted for the green synthesis of AgNPs using proteins, such as Lysozyme (LYZ), bovine serum albumin, and collagen. − Although these methods have various advantages, they require the use of additional reducing agents, ,,, heating, , ultrasound, ultraviolet light, , or organic solvents, which still limits their production and practical application. In addition, for the protein-mediated synthesis of AgNPs, aromatic amino acid residues of proteins play a reducing role to generate AgNPs, and the protein wrapped on the surface of AgNPs functions as a capping agent to maintain the stability of AgNPs .…”

Facile synthesis of a CeMnOx catalytic gel with bacterial microenvironment-responsive antibacterial properties

“…Bacteriostatic nanomaterials are considered to be an effective option that can replace antibiotics in the treatment of bacterial infections. [4][5][6] In particular, nanocatalytic bacteriostatic materials have received widespread attention for the specific bactericidal properties due to the bacterial microenvironmental response properties. [7][8][9] In bacterial infection microenvironments (IME), transition metal nanomaterials with Fenton-like catalytic activity can convert endogenous H 2 O 2 into highly toxic reactive oxygen species (ROS) to destroy tumor cells or bacteria.…”

An ultrasensitive “mix-and-detect” kind of fluorescent biosensor for malaoxon detection using the AChE-ATCh-Ag-GO system

“…Noticeably, AgNPs tend to agglomerate and tarnish in the colloidal phase, this trait may potentially compromise their stability and durability, which can in turn affect their sensing abilities. 17 To overcome these issues, different methods have been devised to stabilize AgNPs, including the deposition of the AgNPs on stable substrates like polymers, silica, or graphene oxide (GO). The objective of the current study was to entrap AgNPs onto GO sheets, as GO is known for its hydrophilicity, high surface area, mechanical strength, electrical conductivity, thermal stability, and chemical reactivity.…”
