Metal nanoparticles and their polymer based composites for biological applications

Development of novel and innovative routes for metal nanoparticles (Au, Ag and Cu NPs) synthesis, different sizes (5-40 nm), shapes, and surface chemistry which makes them useful in a wide spectrum of applications. Structural, morphological and optical characterization of NPs. The focus on individual and particulary polymer/organic molecules functionalized nanoparticles which are prevented from agglomeration and oxidation, and also have improved physicochemical characteristics and functions.

Evaluation of illumination and time dependent antibacterial and photocatalytic properties of surfaces covered with ZnO/Ag composite nanoparticles

Contact with potentially pathogenic microbes found on different surfaces from everyday items to health care settings (e.g. door handles, medical equipment, near-patient surfaces) may potentially harm our well-being. A promising method to reduce the spreading of unwanted microbes on surfaces is the development of antimicrobial surfaces containing photocatalysts that induce the degradation of organic matter under specific illumination conditions. One suitable class of photocatalysts is

Bacterial Adhesion on Different Materials

Biofilm formation on materials leads to high costs in industrial processes, as well as in medical applications. This fact has stimulated interest in the development of new materials with improved surfaces to reduce bacterial adhesion. Standardized tests relying on statistical evidence are indispensable to evaluate the quality and microbial safety of these new materials. Download a poster:

Biosynthesis of microbial pigments and biopolymers

The widespread use of synthetic dyes raises concerns regarding environmental impact and health issues [1], demanding natural and sustainable alternatives such as microbial pigments, which besides colour, provide other functional properties (antimicrobial activity, antioxidant properties, UV protection, among others). Likewise, the replacement of oil-derived synthetic polymers with natural alternatives is another promising opportunity for microorganisms employment. Nontoxic and biodegradable biopolymers such as Bacterial Cellulose [2]

Novel method for the detection of the ‘wet’ and ‘dry’ status of textiles

Survival and growth of microorganisms in the hospital environment must be limited to prevent infection by cross-contamination. Advances in materials/coatings engineering have made antimicrobial materials/coatings (e.g. porous & non-porous surfaces, textiles) an attractive investment for infection control professionals. Due to presence of moisture being a critical factor for some antimicrobial materials, a knowledge of the time taken for a material to return from ‘wet’ to

Growth conditions assessment for prodigiosin production by Serratia plymuthica

The prodigiosins are red pigments produced by a group of bacteria (originally by Serratia spp) that present certain biological activities, such as: antifungal, antibacterial and anticancer. The pigment prodigiosin is a secondary metabolite of the bacterium and is only expressed in certain culture conditions. Pigment production is highly variable among species and is dependence of many factors such as species type, incubation time, temperature, growth

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

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,

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
