Abstract This study investigates the antimicrobial effectiveness of 405 nm light emitting diodes (LEDs) against pathogenic Escherichia coli O157:H7, Listeria monocytogenes , Pseudomonas aeruginosa Salmonella Typhimurium, and Staphylococcus aureus in thin liquid films (TLF) on solid surfaces. Stainless steel (SS), high density polyethylene (HDPE), low (LDPE), borosilicate glass were used as materials typically encountered food processing, service, clinical environments. Anodic aluminum oxide (AAO) coupons with nanoscale topography used, to evaluate effect inactivation. The impact surface roughness, hydrophobicity, reflectivity inactivation was assessed. A 48 h exposure led reductions ranging from 1.3 ( E. ) 5.7 S. log CFU TLF 3.1 6.3 different contact surfaces packaging materials. All curves nonlinear followed Weibull kinetics, better predictions (0.89 ≤ R 2 1.0) compared (0.76 0.99). fastest rate observed small nanopore AAO inoculated L. indicating enhancing potential these These results demonstrate significant promise LEDs for applications processing handling healthcare industry.

UV‐C Disinfection Robots: A Systematic Review

Journal of Field Robotics, Год журнала: 2025, Номер unknown

Опубликована: Май 8, 2025

ABSTRACT The use of ultraviolet (UV‐C) disinfection robots has become increasingly popular in diverse settings, including hospitals, schools, public transportation, and high‐traffic areas, especially following the COVID‐19 pandemic. These offer potential to enhance efficiency reduce human exposure microorganisms. However, application UV‐C light for is not without challenges. challenges include need precise environmental mapping, accurate dose delivery, mitigation safety risks associated with humans animals. This systematic review aims examine current development robots, identify key technological challenges, explore methods used ensure effective safe disinfection. An automated search was conducted Scopus, IEEE Xplore, ACM Digital Library, SpringerLink studies published up July 2023, followed by snowballing gather additional relevant works. A total 96 were reviewed. majority these either did address correct UVGI or lacked appropriate delivery. Additionally, positioning lamps often done subjectively, most incorporate any measures prevent accidents related exposure. Based on this analysis, a new classification proposed, highlighting advancements readiness levels. Despite progress made field, significant remain developing that deliver doses while ensuring operational efficiency. emphasizes further research gaps, particularly concerning navigation algorithms, accuracy, measures.
