“…Currently, 75% alcohol, disinfected water (chlorine-containing disinfectors), and antibiotics are commonly used as an antimicrobial product to reduce the chances of transferring bacteria in public places, , based on their performance of fast and broad-spectrum sterilization. , However, disinfectors containing alcohol and chlorine present a short valid period problem because of their volatility, resulting in multiple and excessive sprays to meet sterilization requirements; thus, they can be enormously wasteful. More importantly, the volatiles of chlorine-containing disinfectants can also cause damage to human respiratory mucosa . Although antibiotics show better bactericidal effects, drug-resistant bacteria caused by antibiotics are harder to kill, and they have been considered one of the greatest threats to humanity by the World Health Organization (WHO), and are unsuitable for prolonged use in public health protection .…”

“…More importantly, the volatiles of chlorine-containing disinfectants can also cause damage to human respiratory mucosa. 9 Although antibiotics show better bactericidal effects, drug-resistant bacteria caused by antibiotics are harder to kill, and they have been considered one of the greatest threats to humanity by the World Health Organization (WHO), and are unsuitable for prolonged use in public health protection. 10 Therefore, it is of great significance to develop a sterilization strategy with robust, long-lasting bactericidal, and on-demand sterilization for public health protection.…”

Excessive and repetitive use of disinfectants poses a significant waste and health hazard; therefore, developing a more secure and efficient sterilization strategy is of great significance in safeguarding public health. Herein, we propose a facile strategy for rapidly fabricating a carboxymethyl chitosan (CMCS)/sliver nanoparticle (AgNPs)/Zn 2+ Janus hydrogel film (CAZ) through in situ asymmetric cross-linking for on-demand sterilization. The Zn 2+ diffusion from the surface toward the interior rapidly constructed the Janus hydrogel structure with a high cross-linking front and a low cross-linking back, realizing ultrafast film formation in approximately 3 s. Ingeniously, the Janus structure confers asymmetric adhesion (167 times difference) to CAZ and forms an antiadhesion front that can be touched by hand and an adhesion back that firmly adheres to the target surface, achieving the positioning and self-matching film formation. Specifically, the antibacterial activity was significantly enhanced by introducing a small amount of AgNPs (0.08 wt %). The three-dimensional movement trajectory of bacteria gradually weakened (10 min) and disappeared (30 min) on CAZ, demonstrating the excellent contact bactericidal performance. Moreover, the CAZ had great biocompatibility, ensuring biosafety. Consequently, in situ preparation of CAZ on the sensitive area surfaces could achieve fast and long-term on-demand sterilization, providing a green and safe strategy for public health protection.

One method to reduce the spread of pathogens is to use clean surfaces. These have long-acting components, and their use would reduce the massive consumption of disinfectants and cleaning products. In order to ensure the safety of these surfaces in water-based systems and prevent mishandling and potential health and environmental risks, this study analyzed the stability of clean surfaces made of polyethylene with three silver compounds with different water solubility. The surfaces were subjected to erosion at 40 °C by immersing them in aqueous solutions of 3% acetic acid (w/v), 50% ethanol (v/v), and deionized water. The ionic silver release was monitored in real-time in situ via voltammetry using an Ag/S2− electrode. Analytical methods such as Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) were employed to elucidate the surface alteration. The plastic residue after immersion varied depending on the pH and the type of solvent used, with a higher plastic migration observed when in contact with the water-ethanol mixture. Furthermore, a correlation was identified between surface stability, oxygen composition in the antibacterial, and water solubility, influencing increased surface oxidation.
