Of great interest in this field are nanocomposites based on halloysite and silver nanoparticles, since they have a broad antimicrobial activity and can reduce the toxic effects of nanoparticles. In this study, we assessed the effect of the AgHNT nanocomposite at a concentration of 0.5 mg/ml on ...
Recently, ZIF-67 was demonstrated to accelerate healing of infected diabetic chronic wounds [24], and to show antibacterial activity against a laboratory Escherichia coli strain when used as ZIF-67/alginate fibers [25]. Here, we synthesized ZIF-67 nanoparticles and analyzed their antibacterial and ...
Previous studies demonstrated that ursolic acid (UA) present in apple pomace displays antimicrobial activity against some microorganisms, but the underlying mechanisms associated with this activity remain unexplored. Furthermore, there are no reports on the effect of UA on carbapenem-resistant Klebsiella ...
In recent years the use of gold nanoparticles (AuNPs) has risen in fields as different as biomedicine or electronics. The most widely used method for their synthesis is citrate reduction, but alternative green methods are being sought. In this sense, the substitution of citrate with natural ...
The nanoparticles were almost saturated by DspB at 0.3 mg/ml, which gave a loading capacity of 76.7%. The immobilization enhanced thermal stability, storage stability and reusability of DspB significantly. Moreover, it also increased antibiofilm activity due to the dual mechanism, including the ...
Synergistic antibacterial and antibiofilm activity of silver nanoparticles biosynthesized by lignin-degrading fungus The fabrication of silver nanoparticles (Ag-NPs) through green chemistry is an emerging area in the field of medical nanotechnology. Ag-NPs were fabricated... A Barapatre,KR Aadil,H ...
nanoparticles have shown great potential in antimicrobial applications. Less is known about nano-enabled surfaces. Here we demonstrate that surfaces coated with nano-ZnO or nano-ZnO/Ag composites are not cytotoxic to human keratinocytes and possess species-selective medium-dependent antibiofilm activity ...

Antibiofilm activityQuorum-sensing inhibitionThis study was aimed at synthesizing polyethyleneimine-coated magnetic nanoparticles and evaluating their effect on patho-genic bacteria. Polyethyleneimine-coated magnetite (PEIMnF) and nickel ferrite (PEINF) nanoparticles were succesfully synthesized and their surface...
In addition, biofoulants like proteins and polysaccharides can poi- son the catalyst surface and result in low catalytic activity. A strategy to overcome this limitation would be to incorporate functionally-active chemical groups into the Pd-encapsulated membranes. One example of such functionally-...
