“…It allows the user to select the type of scattering sphere (in this case, the Coronavirus ) and surrounding medium (in this case, air) and associated variations of refractive index with respect to the incident wavelength of light. This wavelength of 632.8 nm was chosen as the incident wavelength, due to its non-resonant absorbance for most of the bioparticles (bacteria, viruses) [ 8 , 9 , 27 ].…”

“…1 with the elements A 41 and A 14 (including a few other elements) by equating them to 0. However, one can completely validate the preceding lines, only by experimentation by light scattering technique on these bio-particles [ 7 – 9 , 24 ]. The alternative way of real experimentation on such pathogenic bio-particles is by simulation.…”

“…This makes the light scattering technique an interesting approach to exploring small particles ranging from nanometers to micrometer range, to predict their morphology without affecting the particles. This technique has been widely used in diverse areas like astrophysical applications, biomedical applications, nanoscience applications, application in marine issues, atmospheric applications, and astrobiological applications [ 8 , 9 ]. Since it is a non-destructive and non-invasive technique, it has been proven to be a significant tool, especially for the investigation and characterization of biological cells [ 9 ].…”

Issues related to human coronaviru s ( SARS CoV-2 ) are a burning topic of research in present times. Due to its easily contagious nature, real experimentation under laboratory conditions requires a high level of biosafety. A powerful algorithm serves as a potential tool for the analysis of these particles. We attempted to simulate the light scattering from coronavirus ( SARS CoV-2 ) model. Different images were modelled using a modified version of a Monte Carlo code. The results indicate that spikes on the viruses exhibit a significant scattering profile and that the presence of spikes during modelling contributes to the distinctiveness of the scattering profiles.

“…The wells were filled with various concentrations of ZnO nanoparticle suspensions for testing. In addition, the calculation method of MIC and ZOI can also refer to the disk-diffusion method [108,[139][140][141][142]. Consistent with the disk-diffusion method, sterile conditions are also one of the most necessary environmental conditions for antimicrobial performance testing.…”

Advances in nanotechnology have led to the development of antimicrobial technology of nanomaterials. In recent years, photocatalytic antibacterial disinfection methods with ZnO-based nanomaterials have attracted extensive attention in the scientific community. In addition, recently widely and speedily spread viral microorganisms, such as COVID-19 and monkeypox virus, have aroused global concerns. Traditional methods of water purification and disinfection are inhibited due to the increased resistance of bacteria and viruses. Exploring new and effective antimicrobial materials and methods has important practical application value. This review is a comprehensive overview of recent progress in the following: (i) preparation methods of ZnO-based nanomaterials and comparison between methods; (ii) types of nanomaterials for photocatalytic antibacterials in water treatment; (iii) methods for studying the antimicrobial activities and (iv) mechanisms of ZnO-based antibacterials. Subsequently, the use of different doping strategies to enhance the photocatalytic antibacterial properties of ZnO-based nanomaterials is also emphatically discussed. Finally, future research and practical applications of ZnO-based nanomaterials for antibacterial activity are proposed.
