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.
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
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:
The widespread use of synthetic dyes raises concerns regarding environmental impact and health issues , 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 
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
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
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
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,
