“…According to scientific literature, we are now witnessing a rapid evolution of bacteria and a tremendous increase in multidrug-resistant strains largely due to selective pressure and a long-term interaction between the applied antibiotics and bacteria [ 115 , 116 , 117 ]. It seems that antibiotics have been prescribed too often and many times perhaps even inappropriately.…”

Throughout scientific literature, we can find evidence that antimicrobial resistance has become a big problem in the recent years on a global scale. Public healthcare systems all over the world are faced with a great challenge in this respect. Obviously, there are many bacteria that can cause infections in humans and animals alike, but somehow it seems that the greatest threat nowadays comes from the Enterobacteriaceae members, especially Escherichia coli. Namely, we are witnesses to the fact that the systems that these bacteria developed to fight off antibiotics are the strongest and most diverse in Enterobacteriaceae. Our great advantage is in understanding the systems that bacteria developed to fight off antibiotics, so these can help us understand the connection between these microorganisms and the occurrence of antibiotic-resistance both in humans and their pets. Furthermore, unfavorable conditions related to the ease of E. coli transmission via the fecal–oral route among humans, environmental sources, and animals only add to the problem. For all the above stated reasons, it is evident that the epidemiology of E. coli strains and resistance mechanisms they have developed over time are extremely significant topics and all scientific findings in this area will be of vital importance in the fight against infections caused by these bacteria.

“…To further improve the performance of inkjet printing, ZnO UV photodetector is still a difficult issue. There have been many researches investigated the photodetectors modified by metallic NPs to improve the performance [17][18][19][20][21]. However, none of them has fabricated metallic NPmodified ZnO photodetectors by all-inkjet-printing method and the advantages of inkjet printing cannot be fully utilized.…”

To further improve the performance of all-inkjet-printing ZnO UV photodetector and maintain the advantages of inkjet printing technology, the inkjet printing Ag nanoparticles (NPs) were deposited on the inkjet printing ZnO UV photodetector for the first time. The inkjet printing Ag NPs can passivate the surface defects of ZnO and work as surface plasmons from the characterization of photoluminescence (PL), X-ray photoelectron spectroscopy (XPS), and finite difference time domain method (FDTD) simulation. The normalized detectivity (D *) of the Ag NP-modified detector reaches to 1.45 × 10 10 Jones at 0.715 mW incident light power, which is higher than that of 5.72 × 10 9 Jones of the bare ZnO photodetector. The power-law relationship between the photocurrent and the incident light power of the Ag NP-modified ZnO detector is I pc ∝ P 2.34 , which means the photocurrent is highly sensitive to the change of incident light power.

Growing resistance of microorganisms to antibiotics due to their widespread use has led to multiple bacterial infections posing a serious threat to health and human life. Low-frequency ultrasound is one of physical methods for inactivation of pathogenic microbial cells. Application of ultrasound is safe, demonstrates good tissue penetration without significant attenuation of energy, and does not induce microbial resistance. Bactericidal effect of ultrasound is based on acoustic cavitation-the growth and collapse of microbubbles in a liquid medium, resulting in shock waves, shear forces, and microjets which cause irreversible damage and inactivation of microorganisms. The present review combines and analyzes literature data on in vitro and in vivo studies and summarizes works demonstrating the ability of ultrasound, alone or in combination with other methods, to combat pathogenic microorganisms. The results of various studies presented in this review show that low-frequency ultrasound has a noticeable antimicrobial effect on planktonic cells of microorganisms and biofilms. Ultrasound synergistically enhances the effectiveness of other antibacterial agents and activates molecules called sonosensitizers, resulting in the formation of compounds toxic to microbial cells. Ultrasound can also promote local release of antimicrobial drugs from liposomes, as well as from medical implants.
