“…Multiscale ZnO and CuO particles showed superior antimicrobial activity against E. coli ( Figure 5 ) and phage ( Figure 6 ) compared with other scale particles, due to large surface area and multiple scattering under dual UV irradiation [ 5 , 6 , 30 ]. The large surface area of multiscale ZnO (ZnO-(1) > ZnO-(2) by 4.0-fold) and CuO (CuO > Cu 2 O by 5.6-fold) particles induced charge–charge interaction to cause membrane damage of pathogenic microorganisms for enhanced antimicrobial performance [ 48 , 49 ]. The microstructured particle aggregates with polydispersity also showed multiple scattering phenomena improving particular interactions via mass transfer and exchange in multilevel porosity, including the biomodality of macropores and mesopores for enhanced photocatalysis promoting antimicrobial action [ 50 , 51 ].…”

Antimicrobial activity of multiscale metal oxide (MO) particles against Escherichia coli (E. coli) and M13 bacteriophage (phage) was investigated under dual ultraviolet (UV) irradiation. Zinc oxide (ZnO), magnesium oxide (MgO), cuprous oxide (Cu2O), and cupric oxide (CuO) were selected as photocatalytic antimicrobials in MO particles. Physicochemical properties including morphology, particle size/particle size distribution, atomic composition, crystallinity, and porosity were evaluated. Under UV-A and UV-C irradiation with differential UV-C intensities, the antimicrobial activity of MO particles was monitored in E. coli and phage. MO particles had nano-, micro- and nano- to microscale sizes with irregular shapes, composed of atoms as ratios of chemical formulae and presented crystallinity as pure materials. They had wide-range specific surface area levels of 0.40–46.34 m2/g. MO particles themselves showed antibacterial activity against E. coli, which was the highest among the ZnO particles. However, no viral inactivation by MO particles occurred in phage. Under dual UV irradiation, multiscale ZnO and CuO particles had superior antimicrobial activities against E. coli and phage, as mixtures of nano- and microparticles for enhanced photocatalytic antimicrobials. The results showed that the dual UV-multiscale MO particle hybrids exhibit enhanced antibiotic potentials. It can also be applied as a next-generation antibiotic tool in industrial and clinical fields.

“…For instance, Fe 3 O 4 NPs are highly biocompatible antimicrobial and anticancer agents, and their magnetic properties make them good candidates for probes in magnetic resonance imaging and as targeted drug carriers. 159,160 Fe 3 O 4 NPs can be easily functionalized with ammonium-based polymeric IL for potent antibacterial properties. They can be used as novel and recyclable water disinfectants.…”

Investigations of the adaptation of living organisms/human body to various extreme factors are extremely important. Aim. To characterize and analyze the results of research of structural and functional interdependencies of organisms in extreme conditions. Methods. Comparative analysis of the registered biochemical, physiological characteristics of the body, mathematical modelling of underlying mechanisms on their basis, information and computer technologies. Results. Deviations of organisms’ functions during adaptation processes caused changes in some structures of organism. Significant role of quantitative and qualitative changes of the erythrocyte formation system in the reliability of organisms functioning in extreme conditions in highlands was confirmed. The changes in red and white blood cells reflected largely the relationships between the organisms’ reactivity and resistance. The dependences on degree of rarefaction of the air, mode of climbing, effects of athlete’s training, etc. were revealed. Adaptive hemolysis of erythrocytes, when the biologically active substances were released from blood cells and acted as messengers, were shown to be the triggers capable to change cell metabolism; they played significant roles in reliability of organisms functioning. The set of program models was developed. Results were applied successfully for training of athletes for high-altitude climbing. Conclusions. Results of the studies on the structural and functional interdependencies of organisms in extreme conditions were reviewed and analyzed. Results of mathematical modeling coincided with the results obtained in experiments and observations. In the process of adaptation to hypoxia human organism behaved likes an ultrastable system. Obtained results can be applied in practice.
