“…In this technique 6.0 mm diameter discs were impregnated with different concentrations of nanoparticles (0–500 µg/disc) followed by sterilization. Overnight grown 0.1 mL culture (inoculums) of Staphylococcus aureus and Pseudomonas aeruginosa strain 4EA were then spread‐plated on Muller–Hinton agar plates separately and nanoparticle impregnated discs were placed over them followed by incubation at room temperature for 24 h . Zone of inhibition caused by nanoparticles was recorded to determine their antimicrobial activity.…”

“…The high antibacterial and chemical catalytic activity of metal nanoparticles has been credited to their nano‐size and high surface‐to‐volume ratio, which allows them to interact with microbial membrane surfaces and also helps to speed up chemical reactions , , , , . Other properties of nanomaterials that influence toxicity include chemical composition, shape, surface structure, surface charge, aggregation and solubility, and presence or absence of functional groups , , , . Interaction of silver nanoparticles with bacteria and their stability in the growth medium depends on their small size and results in greater retention time for bacterium–nanoparticle interaction , .…”

BACKGROUND: As a result of evolution of multiple drug resistance in human pathogens (bacteria) there is increasing demand for novel antibacterial agents, and recently, due to their high antibacterial and catalytic activities, metal nanoparticles have attracted the attention of researchers and medical microbiologists worldwide. RESULTS: Ni‐, Ce‐ and Ag‐doped MnO2 nanoparticles were synthesized by a co‐precipitation method. Antibacterial activity of these synthesized nanoparticles on methicillin‐resistant Staphylococcus aureus and lead‐resistant Pseudomonas aeruginosa strain 4EA was investigated using a disc diffusion method. Only Ag‐doped MnO2 nanoparticles showed an antibacterial property against methicillin‐resistant Staphylococcus aureus and lead‐resistant Pseudomonas aeruginosa strain 4EA at low levels of 60 µg/disc and 85 µg/disc, respectively. Scanning electron microscopy and transmission electron microscopy (SEM‐TEM) coupled with energy dispersive X‐ray (EDX) analysis revealed the nano‐size and composition of these synthesized nanoparticles. CONCLUSION: It was confirmed through a disc diffusion method that chemically synthesized silver doped MnO2 nanoparticles have antibacterial activity against multidrug‐resistant Staphylococcus aureus and lead‐resistant Pseudomonas aeruginosa strain 4EA at low levels therefore these nanoparticles can be employed to fight and prevent infections caused by multidrug‐resistant bacterial pathogens. © 2012 Society of Chemical Industry

“…Some of antimicrobial agents are extremely irritant and toxic to humans. Thus, the formulation of new effective, resistance-free, low-cost, and natural origin antimicrobial agents is of great interest [4][5][6][7][8][9]. An antibacterial drug in medication is used to treat bacterial infections.…”

This paper describes the isolation of carbon nanoparticles (CNPs) from kitchen soot, characterization of the CNPs by UV/visible spectroscopy, SEM and XRD, and their antimicrobial action. The antibacterial activity of the isolated carbon nanoparticles was tested against various pathogenic bacterial strains such as Gram-negative Proteus refrigere and Pseudomonas aeruginosa and Gram-positive Staphylococcus aureus and Streptococcus haemolyticus. The inhibition zones were measured, and it was found that the carbon nanoparticles isolated from natural sources are active against these Gram-negative and Gram-positive bacterial strains.

To improve the laundering durability of the silver functionalized antibacterial cotton fabrics, a radiation-induced coincident reduction and graft polymerization is reported herein where a pomegranate-shaped silver nanoparticle aggregations up to 500 nm can be formed due to the coordination forces between amino group and silver and the wrapping procedure originated from the coincident growth of the silver nanoparticles and polymer graft chains. This pomegranate-shaped silver NPAs functionalized cotton fabric exhibits outstanding antibacterial activities and also excellent laundering durability, where it can inactivate higher than 90% of both E. coli and S. aureus even after 50 accelerated laundering cycles, which is equivalent to 250 commercial or domestic laundering cycles.
