Special Issue Information

Dear Colleagues,

Nosocomial infections (NIs) have been a worldwide healthcare issue for decades. Due to the incredible increase of bacterial resistance towards medicines, infections continue to proliferate, and thousands of deaths in hospitals have been counted. Some studies have provided an estimation of the number of NIs annually observed in the US, where around two million patients suffer from NIs during hospital stays and nearly 90,000 are estimated to die. In the UK, 300,000 people acquire infections in hospitals each year, resulting in nearly 5000 deaths. In addition to these alarming statistics, more than £1 billion per year in UK and at least $10 billion annually in the US are spent to struggle against healthcare-associated infections (HAIs) according to the Office for National Statistics, and these costs come directly out of the hospital’s wallet. The spread of micro-organisms should be urgently limited because the projected mortality rate due to HAIs is estimated to reach more than 10 million per year in 2050, which is higher than the projected rate for cancer.

In order to prevent this risk, many devices used in hospitals (surgical/food trays, stainless steel substrates, catheters, operation tools) have been covered with antibacterial coatings which could either kill micro-organisms (biocidal coatings) or prevent their adhesion/growth (passive coatings). In this context, a wide diversity of materials, including nature-inspired materials that mimic fauna-based surfaces, cationic-polymer-based materials, photoactive materials and nanocomposites containing metal and metal oxide nanoparticles (NPs), have been described in literature. While impressive antibacterial properties were often reported, many challenges in terms of durability, sustainability and efficiency in “real” (hospital) conditions remain. Moreover, beyond coatings, 3D materials exhibiting antimicrobial properties could find tremendous medical applications, especially in tissue engineering

This Special Issue is dedicated to original research and review papers of the highest quality that consider the synthesis and design of new antimicrobial materials (e.g., coatings, films, hydrogels, 3D systems) which significantly prevent the growth of or eradicate bacteria. While centered on materials science, contributions to this Special Issue are expected to have significant microbiological relevance.

The worldwide, extraordinary outbreak of coronavirus pandemic (i.e., COVID-19) and other emerging viral expansions have drawn particular interest to the design and development of novel antiviral, and viricidal, agents, with a broad-spectrum of antiviral activity. The current indispensable challenge lies in the development of universal virus repudiation systems that are reusable, and capable of inactivating pathogens, thus reducing risk of infection and transmission. In this review, science-based methods, mechanisms, and procedures, which are implemented in obtaining resultant antiviral coated substrates, used in the destruction of the strains of the different viruses, are reviewed. The constituent antiviral members are classified into a few broad groups, such as polymeric materials, metal ions/metal oxides, and functional nanomaterials, based on the type of materials used at the virus contamination sites. The action mode against enveloped viruses was depicted to vindicate the antiviral mechanism. We also disclose hypothesized strategies for development of a universal and reusable virus deactivation system against the emerging COVID-19. In the surge of the current, alarming scenario of SARS-CoV-2 infections, there is a great necessity for developing highly-innovative antiviral agents to work against the viruses. We hypothesize that some of the antiviral coatings discussed here could exert an inhibitive effect on COVID-19, indicated by the results that the coatings succeeded in obtaining against other enveloped viruses. Consequently, the coatings need to be tested and authenticated, to fabricate a wide range of coated antiviral products such as masks, gowns, surgical drapes, textiles, high-touch surfaces, and other personal protective equipment, aimed at extrication from the COVID-19 pandemic.
