Article Abstract
Antimicrobial and self-cleaning nanomaterial coatings have attracted significant research attention in recent years due to the growing global threat of infectious diseases, the emergence of new diseases such as COVID-19, and increases in healthcare-associated infections. Although there are many reportedly successful coating technologies, the evaluation of antimicrobial performance is primarily conducted under simple laboratory conditions without adequate testing under real environmental conditions that reflect practical use and more importantly, reveal unintended outcomes. Furthermore, there is no standardized evaluation methodology to assess the long-term stability or the consequences associated with coating deterioration, such as the ecological impacts of nanomaterials or the proliferation of antibiotic-resistant bacteria/genes. In this review, we propose a precautionary framework that integrates a rigorous assessment of potential risks and limitations of nanomaterial coatings for antimicrobial applications as intrinsic to a comprehensive evaluation of their benefits. In addition, we summarize some emerging coating technologies as promising strategies to minimize unintended risks and enhance performance.

Polarity switching photoelectrochemical (PEC) sensing effectively addresses the issue of false positive or negative results that arise from single signal on or off in PEC systems. In this study, a novel core-shell ternary composite material of S-TiO/CDs/PCN-224 was constructed by growing PCN-224 on the surface of spherical titanium dioxide (S-TiO) while simultaneously confining carbon quantum dots (CDs). This ternary composite can produce cathodic and anodic PEC signals under visible (420-800 nm) and ultraviolet (UV)-Vis (320-800 nm) excitation, respectively.

Geckos have high skin bacterial diversity, even though gecko skin has antimicrobial, self-cleaning properties. To gain a better understanding of environment-animal-microbiome interactions in these reptiles, we investigated skin bacteria on seven northern Australian gecko species from five sites and two seasons (n = 234) and found support for our hypotheses of divergent communities between species, sites and seasons. Despite that support, predictor variables had low explanatory power, which increased when focusing within a site or species, explaining up to 40% and 27% of the variation among samples at a site or on a species found in multiple sites, respectively.

3D printing enables the fabrication of complex, customizable biomedical polymer structures. The integration of superhydrophobicity─known for its unique self-cleaning, antibacterial, and anticoagulant properties─can significantly enhance the functionality of 3D-printed polymer in biomedical applications. However, conventional coating-based approaches for imparting superhydrophobicity suffer from poor mechanical stability due to weak adhesion between the coating layer and the substrate.

This study reports the design and fabrication of a magnetic nanoporous carbon-based recyclable surface-enhanced Raman scattering (SERS) substrate Co/C@Ag/g-CN, which can simultaneously achieve SERS detection and visible-light photocatalytic degradation of malachite green (MG). Co/C and g-CN can spontaneously adsorb and concentrate MG near plasmonic nanoparticles, thereby enhancing the SERS response. The substrate exhibited a SERS enhancement factor of approximately 1.

Enamel white spot lesions (WSLs) not only compromise the efficacy of orthodontic treatments but also pose risks to dental health. Although clear aligners offer the advantage of facilitating oral hygiene maintenance, their full-coverage crown design impedes the self-cleaning function of saliva, potentially leading to extensive white spot formation. This study pioneers the application of a PA@PEI-Cl coating to transparent aligners.
