Ultrasonic coating of medical textiles with antimicrobal nanoparticles

According to European Centre of Disease Prevention and Control (ECDC), every year 5-6% of patients come to nosocomial infections. Due to rapid spreading of superbacteria, resistant to any antibiotics the situation is becoming serious. Decreasing of the number of hospital

Functionalization of polydimethylsiloxane and stainless steel surfaces with disinfectants

Microbial adhesion onto surfaces is at the root of serious problems in many areas, often compromising the disinfection practices. In clinical settings, microorganisms can colonize abiotic surfaces, equipment and medical devices. This problem is aggravated when microorganisms adopt a sessile

Equisetum arvense mediated synthesis of silver nanoparticles and its application as antibacterial suspension

High consumption of antibiotics has led to resistance of pathogenic microorganisms, which prompted the testing of antimicrobial activity of various plant extracts or other substances in order to find new antimicrobial agents. Alternatively, silver and silver-based topical dressings have been

Agar/ nanosilver composite coatings for prevention of biofilm formation

Bacterial contamination on various surfaces is very common and causes serious problems, particularly on hospital surfaces/furniture and medical devices The formation of biofilms on such surfaces is recognized as the most critical biological contamination due to a difficult removal of

STSM: Fabrication of electrospun antimicrobial nanofibers based on phytochemicals

STSM asignment description: The objective of this STSM is the fabrication of phytochemical based antimicrobial nanofibers via electrospinning which may find application in medical devices for the purpose of infection prevention and control. Through collaboration with TÜBİTAK MRC and Zurich

STSM: Evaluating the anti-biofilm activity of surfaces composed of ZnO/Ag heterostructures

STSM completed: ZnO/Ag heterostructures are expected to exhibit UVA-induced photocatalytic effect which are due to the presence of ZnO and magnified by the presence of Ag nanoparticles. While these surfaces have been shown to be effective against planktonic bacteria, their

Comparative performance of a panel of commercially available antimicrobial nanocoatings in Europe

Background Bacterial resistance against the classic antibiotics is posing an increasing challenge for the prevention and treatment of infections in health care environments. The introduction of antimicrobial nanocoatings with active ingredients provides alternative measures for active killing of microorganisms, through

Mechanism of copper surface toxicity in Escherichia coli O157:H7 and Salmonella involves immediate membrane depolarisation followed by slower rate of DNA destruction which differs from that observed for Gram-positive bacteria

We have reported previously that copper I and II ionic species, and superoxide but not Fenton reaction generated hydroxyl radicals, are important in the killing mechanism of pathogenic enterococci on copper surfaces. In this new work we determined if the

N-halamine copolymers for biocidal coatings

A vinyl N-halamine acrylamide monomer was copolymerized with silane-, epoxide-, and hydroxyl group-containing monomers. The resultant copolymers were coated onto cotton fabric through hydrolysis of alkoxy groups with formation of silyl ether bonding, opening of the epoxide ring and subsequent
