Abstract
The design of advanced materials with superb anti-bacterial efficiency by engineering appropriate surface properties has now become a consolidated strategy to improve the functional properties of polymers, metals, and a variety of biomedical materials. Antimicrobial coatings can create a healthier living and working environment and offer holistic solutions to people with health problems. This Tutorial will serve as a reference point for scientists pursuing sustainable antimicrobial coatings development, by providing a design framework and a toolbox for enabling plasma-based technologies in additive engineering of new materials. A succinct description of how novel, efficient methods based on non-equilibrium reactive plasma chemistries can be applied to produce sophisticated, high-value advanced coatings with the anti-bacterial or antifungal function will be used to illustrate the utility of plasma methods. Described plasma-based methods can minimize the process steps and dramatically reduce the use of expensive and hazardous reagents, which is a point of high interest in the development of novel sustainable and green manufacturing processes. The Tutorial aims to provide an overview of the principle and state-of-the-art in plasma technology, which is useful for researchers and broad auditoria of students working in antimicrobial materials development and additive engineering.

The results in this study showed that a 96% reduction in L. monocytogenes biofilm formation was observed on both polyethylene glycol (PEG)-grafted samples compared with their corresponding unmodified control
Summary
Recent progress in materials engineering and polymers science has resulted in the last few decades in the development of many new materials with improved mechanical, chemical, and physical properties. Wet chemistry methods were developed and applied first for manufacturing anti-bacterial materials. Plasma can establish a controlled reactive physicochemical environment that is amenable to enabling a variety of plasma-based surface engineering methods for surface activation, coating deposition, and surface nano-structuring of virtually any solid material. Plasma processing is one kind of technique that uniquely features several advantages over traditional wet chemistry approaches in the field of antimicrobial material. The Tutorial is expected to provide the readers with the description of currently available plasma technologies in the field of anti-bacterial materials and helps with an appropriate choice of the methods for surface engineering to manufacture advanced materials with biocidal activity
