Summary: The review discusses the strategy of combining ultrasonic antimicrobial treatment with catalysts, highlighting the continuous development of organic sonosensitizers and inorganic sonocatalysts. By using nanomaterials, the traditional ultrasonic parameters have been altered, leading to improved efficiency in bacterial inactivation. The review also examines the mechanisms of different combinations on bacterial inactivation.

Summary: Red phosphorus/titanium oxide nanofibers were developed for efficient water disinfection, rapidly killing E. coli and S. aureus under white LED irradiation. The enhanced antibacterial activity was mainly attributed to improved light absorption and charge separation at the TiO2@RP interface.

Summary: This study investigates the mechanisms of virus inactivation using different light-based strategies on an HIV-based pseudotyped model of SARS-CoV-2 (SC2). UV-C light and Photodithazine photosensitizer (PDZ) were used to photoinactivate (PI) and photodynamic inactivate (PDI) the virus, respectively. Both UV-C and PDZ treatments damaged the single stranded RNA (ssRNA) and spike protein of the virus to different extents. However, the virus was still able to enter the infected cells. UV-C treatment primarily damaged ssRNA, while PDZ-based PDI primarily destroyed the spike protein and viral membrane. Both UV-C and PDZ treatments resulted in the inability of the cells to express the reporter gene, indicating viral inactivation.

Summary: This study compared the disinfection performance of UV-LEDs with different wavelengths on marine microalgae and evaluated the sensitivity of different detection methods. The results showed that there was no significant difference in the inactivation efficiency of UV-LEDs with different wavelengths (except for 300 nm) when using the VS assay, but significant differences were observed when using the MPN assay. Moreover, the study found that the wavelength of 265 nm had the highest inactivation efficiency, while 285 nm achieved optimal energy efficiency.

Summary: A reactor engineering approach was used to mathematically describe microbial inactivation during continuous UV-C light processing of liquid foods. The experiments revealed a variable order kinetic for the inactivation of Lactobacillus rhamnosus, with faster and higher steady-state log reduction achieved under certain experimental conditions.

Summary: This study demonstrates the potential of using EDA-CDots to prevent and inhibit biofilm formation at an early stage, especially showing better inhibitory effects when added early. By coupling with chelating agents to disrupt EPS protection, CDots showed significantly enhanced photoinactivation of biofilm-associated cells.

Summary: The spread of antibiotic-resistant bacterial pathogens is a global public health issue, especially among hospitalized patients. Current disinfection techniques are ineffective due to the multiple antibiotic-resistance genes carried by these pathogens. Nanotechnology offers novel opportunities for developing physical-based disinfection methods.

Summary: The development of antibiotic resistance poses a major challenge for effective treatment of infectious diseases, highlighting the need for a safe method to effectively inactivate pathogenic microbes without developing resistance. Ultraviolet irradiation, known for its microbial inactivation ability, is increasingly being studied for human disinfection applications as an emerging field. Studies focusing on microbial inactivation mechanisms associated with ultraviolet irradiation wavelength and safety issues show promising results in both animal and human studies.

Summary: The study demonstrated the effectiveness of intense pulsed light (IPL) treatment on the inactivation of seven foodborne gram-positive bacteria, with high levels of inactivation achieved under different conditions. Mature biofilm showed the strongest resistance, followed by early biofilm, while planktonic state was the most susceptible. IPL may serve as a method for surface decontamination, reducing microbial contamination on food surfaces.
