“…A crucial strategy in disease prevention involves the regular cleaning and frequent disinfection of touchscreens. Nevertheless, conventional disinfection methods, which rely on chemicals like ethanol, isopropanol, and hypochlorite, are unsuitable for disinfecting touchscreens due to their sensitivity to these substances [ 9 ]. In addition to touchscreen devices, other surfaces, like door handles, elevator buttons, and escalator rails, in public areas can also become contaminated and pose a potential risk of the spread of microbial pathogens [ 10 ].…”

The escalating presence of pathogenic microbes has spurred a heightened interest in antimicrobial polymer composites tailored for hygiene applications. These innovative composites ingeniously incorporate potent antimicrobial agents such as metals, metal oxides, and carbon derivatives. This integration equips them with the unique ability to offer robust and persistent protection against a diverse array of pathogens. By effectively countering the challenges posed by microbial contamination, these pioneering composites hold the potential to create safer environments and contribute to the advancement of public health on a substantial scale. This review discusses the recent progress of antibacterial polymer composite films with the inclusion of metals, metal oxides, and carbon derivatives, highlighting their antimicrobial activity against various pathogenic microorganisms. Furthermore, the review summarizes the recent developments in antibacterial polymer composites for display coatings, sensors, and multifunctional applications. Through a comprehensive examination of various research studies, this review aims to provide valuable insights into the design, performance, and real-time applications of these smart antimicrobial coatings for interactive devices, thus enhancing their overall user experience and safety. It concludes with an outlook on the future perspectives and challenges of antimicrobial polymer composites and their potential applications across diverse fields.

“…8 Moreover, some manufacturers advise against the use of chemical disinfectants such as ethanol and isopropanol for cleaning touchscreens due to the sensitivity of touchscreens. 9 In this respect, antimicrobial coatings are a potential solution for preventing the bacterial contamination of touchscreens. In particular, metal and metal oxide-based nanomaterials have been widely used as antimicrobial coatings because their small size and high specific surface area make them highly toxic to pathogens.…”

“…Chemical disinfectants such as ethanol, hypochlorite and chlorhexidine, as well as ultraviolet irradiation in the spectral range of 200–280 nm, are known to offer good antimicrobial properties [ 12 ], [ 13 ], [ 14 ], [ 15 ], [ 16 ], [ 17 ], [ 18 ], [ 19 ], [ 20 ], [ 21 ]. Unfortunately, both techniques also suffer some significant drawbacks.…”

“…The application of chemical disinfectants is prohibited by some device manufacturers and typically requires manual execution, limiting potential applications [ 22 ], [ 23 ]. Muniz de Oliveira et al fear that typical hospital disinfectants might damage devices like tablets and smartphones [ 21 ], although ethanol-impregnated wipes, for instance, are allowed at least for some touchscreen devices [ 24 ], [ 25 ]. They are successful against many bacteria [ 12 ], [ 13 ], [ 26 ], but not against Clostridioides difficile for instance and some viruses [ 12 ].…”

Background: Touchscreens are usually microbially contaminated and can therefore act as fomites inside and outside healthcare environments. Due to the increasing use of such touchscreens and the growing awareness of infection risks, approaches that allow safe and automatic disinfection are desired. Ultraviolet (UV) irradiation, with its known antimicrobial efficacy, could achieve this goal, but should be executed with limited touchscreen degradation, disinfection duration, and energy consumption. It should also pose as little harm as possible to humans even in case of failure. Materials and methods: A literature search was performed first to identify the microorganisms most commonly found on touchscreens. Then, the 90% reduction doses (D90 doses) for the different relevant microorganisms and UV spectral ranges were determined from the literature, and irradiation doses are suggested that should reduce most of these important microorganisms by 5 log-levels. Results: The most frequent microorganisms are staphylococci, bacilli, micrococci, enterococci, pseudomonads and E. coli with small differences between hospital and community environments, if antibiotic resistance properties are ignored. The determined irradiation doses for a 5 log-reduction of the most frequent microorganisms are about 40 mJ/cm 2 , 80 J/cm 2 , 500 J/cm 2 and 50 mJ/cm 2 for the UV spectral ranges UVC, UVB, UVA and far-UVC, respectively. These doses are also sufficient to inactivate all nosocomial ESKAPE pathogens on touchscreens by at least 99.999%. Conclusion: Disinfection is achievable in all UV spectral ranges, with UVC being the most effective, enabling automatic disinfection within a minute or less. The much higher doses required in the UVB and UVA spectral range result in much longer disinfection durations, with the advantage of a reduced risk to humans. For all kinds of UV irradiation, the doses should be limited to reasonable values to avoid irradiating an already more or less sterile surface and to prevent degradation of touchscreen devices.
