Emulsion Electrospun Fiber Mats of PCL/PVA/Chitosan and Eugenol aimed for antimicrobial wound healing applications

In recent years, the damaging effects of antimicrobial resistance relating to wound management and infection have driven the ongoing development of composite wound dressing mats containing natural compounds, such as plant extracts and its derivatives. The present research reports the fabrication of novel electrospun Polycaprolactone (PCL) / Polyvinyl Alcohol (PVA)/ Chitosan (CH) fiber mats loaded with Eugenol (EUG), an essential oil extracted from cloves, known

Antimicrobial potency of differently coated 10 and 50 nm silver nanoparticles against clinically relevant bacteria Escherichia coli and Staphylococcus aureus

Silver nanoparticles (nanoAg) are effective antimicrobials and promising alternatives to traditional antibiotics. This study aimed at evaluating potency of different nanoAg against healthcare infections associated bacteria: Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus. A library of differently coated nanoAg of two different sizes (10 and 50 nm) were prepared using coating agents poly-L-Lysine (PLL), cetyltrimethyl-ammonium bromide (CTAB), citrate (CIT), polyvinyl-pyrrolidone (PVP), polysorbate 80 (Tween 80), and

The AMiCI WG2 workshop “Antimicrobial Coatings Applied in Healthcare Settings – Efficacy Testing”, Berlin, Germany

On 7-8 June 2018, the AMiCI WG2 workshop was held, combined with the Action Core Group Meeting, at the Bundesanstalt für Materialforschung und -prüfung (BAM) in Berlin, Germany. The European Union COST Action AMiCI  brings together experts on the synthesis, use and assessment of unwanted side effects of antimicrobial coatings. The project is coordinated by dr. Francy Crijns (Zuyd University of Applied Sciences and Technology,

Welcome Bosnia and Herzegovina became new partner countries in the AMiCI COST Action

Following the E-vote on the approval of Bosnia and Herzegovina as a partner country in the AMiCI Action, thise countries became new partner countries in the AMiCI COST Action. Proposal has been accepted by 18 countries voting Yes and other 13 countries abstaining, which – according to the COST rules – is equal to the positive vote. The outcome of this vote will be recorded

Rapid in situ assessment of Cu-ion mediated effects and antibacterial efficacy of copper surfaces

Release of metal ions from metal-based surfaces has been considered one of the main drivers of their antimicrobial activity. Here we describe a method that enables parallel assessment of metal ion release from solid metallic surfaces and antimicrobial efficacy of these surfaces in a short time period. The protocol involves placement of a small volume of bioluminescent bacteria onto the tested surface and direct measurement

Network day NanoSilver 2018

On the occasion of a joint project in the network, the Network day NanoSilver 2018 takes place at the university medical centre in Regensburg (UKR). At the UKR, various surfaces within the emergency room are equipped with antimicrobial silver. Over a period of one year, the innovative coatings are compared with conventional surfaces to evaluate their effectiveness. Of course, the project will be presented at

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 infections can be obtained by using anitibacterial coatings at textiles. Textiles should be antibacterial, coating durable and not harmful for patients. There are plenty of

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 lifestyle and live in biofilms. The best approach to prevent the occurrence of cell adhesion and biofilm formation, with subsequent spread of microorganisms between equipment

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 used to treat bacterial infections. To overcome the problems associated with the excessive usage of antibiotics and chemicals, there is a need of eco-friendly synthesis
