Theme: Antimicrobial coatings - novel technical approaches
Date/time: 16th of June 2021, 2 PM - 4 PM CEST (12 PM UTC)
Prof. Dr. Albert Schenning - Technical University Eindhoven (TUe) - Eindhoven (Netherlands)
Taking dynamic coatings to the next level; challenges and obstacles
Kathleen Stout, PhD. - Zuyd Hogeschool & Cyriel Mentink, PhD. - CHILL - Geleen (Netherlands)
MSS-Coatings: Applications and Features
Robert Beckers - VeroMetal Holding B.V. - Landgraaf (Netherlands)
Surfaces with antimicrobial properties are based on coatings with special metal- or metal oxide-layers or on immobilised biocides. The antimicrobial efficacy of such surfaces depends on the release of the active substances and can be exhausted (leach off) depending on the duration of use and conditions of use. New promising approaches from research are based on photodynamically switchable surface coatings that can change their topology in distinct microscale areas and thereby prevent the adhesion of microorganisms or, for example, also of dirt. Due to the changes in the surface topology, which can in principle be switched over an infinite number of cycles, the properties of such novel coating systems are available in unlimited quantities. In parallel, surface coatings using catalytically active Multi-Stimulus Systems also have a principally unlimited and inexhaustible effectiveness that is regenerated by each excitation cycle, which predisposes these coating systems to demanding applications.

Theme: Regulatory requirements for antimicrobial surfaces
Date/time: 20th of May 2021, 2 PM - 4 PM CEST (12 PM UTC)
Coatings with antimicrobial activity provide new approaches to improve the hygienic status of surfaces on a long-term or on a permanent level. By inactivation of bacterial, fungal or viral pathogens they contribute to the hygiene of products at manufacturing sites or directly to human, animal or plant health and wellbeing. Due to the property to compromise survival or infectiousness of pathogens these coatings i.e. the contained biocidal agents underlay the requirements of the European Biocide Regulation (EU) No 528/2012 when the coatings are sold and made available on the market.
Within AutoProtect-Webinar #2 an overview about regulatory requirements is given and discussed. A sol-gel coating with intricate mechanism under the implementation of classical biocidal agents versatile for a broad range of applications, which is already on the market, is presented. In addition, a new class of plasma-generated surfaces coatings with catalytic activity against various pathogens as well as organic soilings is introduced.
Regulatory requirements for antimicrobial surfaces

A sol-gel-Coating for permanently antimicrobial surfaces

Plasma-based antimicrobial coatings
Dr. Ben Dhia Salem - Plasmatreat GmbH. (Germany)
Dr. Hans-Joachim Weintz (NRWO!)
This presentation describes the genesis of a highly resistant thin film coating with permanent anti microbial activity, derived from the joined Interreg funded research project "Sustainable Surface and Membranes (S2M)" of Netzwerk Oberfläche NRW e.V. from 2016 to 2018.
Basic idea was to include the biocidal function into the polymer as an intrinsic property. 2 different ways were pursued in the project. One of them leading to the subject of this presentation combined the benefits of a sol-gel hybrid thin film coating with the intelligence and findings of the development of medical devices like stents leading to bio-repulsive coating surfaces which can be used as base for anti-adhesive marine coatings as well as antibacterial and antiviral coatings – a highly actual topic!
Peter D Askew (IMSL)
Biocidal active substances are used to treat a wide range of materials and articles both to protect them from biodeterioration in use, extend their service life and to introduce new functions, especially hygienic ones. Many countries regulate and license the use of biocides and impose restrictions on their applications to protect against unintended effects arising from their use. While such regulation will have little direct impact on most end-users of biocides, their use to add new functionality to articles does. This presentation will provide an overview of this impact and what this means to those developing articles intended to deliver hygienic benefits through their use.
Dr. Dhia Ben Salem (Plasmatreat)
Within Webinar No. 2, an introduction of plasma assisted modifications of surfaces and plasma thin film deposition will be presented as potential strategies to provide antibacterial and/or antifouling properties to different substrates such as glass, metals or even polymers. Different combinations of coatings have been considered in order to be as efficient as possible overtime by providing inner catalytic properties to the plasma deposited layer that should enable the antimicrobial properties to be regenerated using external stimuli such as thermal energy, mechanical energy or light radiation energy.In this session, Plasmatreat will present the latest results obtained within AutoProtect project and focused on the deposition of Anti-microbial coatings using atmospheric pressure plasma processes.

Project AutoProtect: Multi-Stimulus-System Coatings – solving many problems with one coating
Dr. Markus Wehrl, DGKH e.V, wfk – Cleaning Techn. Inst. e.V., (DE)
Pathogens deposited on surfaces present a potential infection risk as these pathogens can be transferred to susceptible persons by contact with hands, fabrics or objects and subsequently cause infections. Such infections that occur in health care facilities are well known as dreaded „hospital acquired infections“, harming vulnerable patients.
Within Webinar No. 1 the impact of surface hygiene on the prevention of infections in health care institution amongst others is discussed. Removal, or better inactivation of pathogens on surfaces can be provided by disinfection procedures. Therefore a large panel of different disinfectants for various purposes is available, however disinfectants used in health care facilities have to comply to highest requirements in effectiveness and reliability. But beside health care facilities with their special emphasis on infection risks also in technical areas with low or negligible infection risks the load with microorganisms or soilings is often unwanted and can compromise the product quality due to failure, malfunction or corrosion effects. New approaches to provide a better long-term hygiene and cleanliness of surfaces based on catalytically active surfaces coatings are discussed.
