Stopping global pandemics is an important and urgent task for the scientific community. Significant loss of life and economic activities causes severe impacts on countless families and individuals at every corner. Like all the pandemics recorded in history, close physical contact and poor disinfection on hand-touched surfaces always lead to the rapid transmission of germs and viruses, and ultimately to the uncontrollable pandemics. Since smart devices (e.g. cell phones, watches, etc.) have been widely adopted in modern society and individuals, the touch-control panels, usually integrated with the monitor display, become a major hazard of disease transmission due to frequent touching in daily life. This makes the touch panel of smart devices to be a "transmission hub" to spread bacteria and viruses on all the other surfaces touched by human hands. Therefore, antibacterial coatings on these panels could significantly inhibit disease transmission. Nevertheless, such the strategy may only work if the major population is willing to adopt antibacterial coatings on the surface of all kinds of smart devices. This posts the new criteria for the public willing to accept antimicrobial coating: high transparency, easy operation, generic depositing substrates, and long duration. Low transparency coatings shield or degrade the visual quality of the control display panels, almost impossible to convince the public to accept. Complicated coating procedures only compatible with specific substrates would face the same difficult situations. High durability of coatings, meanwhile, reduces the frequency to repair or reinforce the antimicrobial activities.
