“…Moreover, addition of dimethyl sulfoxide to the solution facilitates penetration of nanoparticles through bacterial cell membranes, thereby increasing the inhibition zones. [ 311 ] In another study, silica nanoparticles coated with different metal oxides such as Ag 2 O or Cu 2 O have higher antibacterial activity than those coated with Ce 2 O or NiO. [ 312 ] When the antibacterial activity of four nanoparticles containing oxides of Al, Ti, Si, and Zn are compared, ZnO nanoparticles have higher toxicity than SiO 2 and Al 2 O 3 while TiO 2 does not show any toxicity against B. subtilis , E. coli or P. fluorescens .…”

Microbial colonization on material surfaces is ubiquitous. Biofilms derived from surface-colonized microbes pose serious problems to the society from both an economical perspective and a health concern. Incorporation of antimicrobial nanocompounds within or on the surface of materials, or by coatings, to prevent microbial adhesion or kill the microorganisms after their attachment to biofilms, represents an important strategy in an increasingly challenging field. Over the last decade, many studies have been devoted to preparing meta-based nanomaterials that possess antibacterial, antiviral, and antifungal activities to combat pathogen-related diseases. Herein, an overview on the state-of-the-art antimicrobial nanosized metal-based compounds is provided, including metal and metal oxide nanoparticles as well as transition metal nanosheets. The antimicrobial mechanism of these nanostructures and their biomedical applications such as catheters, implants, medical delivery systems, tissue engineering, and dentistry are discussed. Their properties as well as potential caveats such as cytotoxicity, diminishing efficacy, and induction of antimicrobial resistance of materials incorporating these nanostructures are reviewed to provide a backdrop for future research.

“…Metal NPs were obtained in a plasma electric arc discharge as published previously [14,28] using ethanol as a solvent. They were characterized by size using a transmission electron microscope LEO 912 AB OMEGA (Carl Zeiss, Oberkochen, Germany) with energy filter and Keller system; by size distribution and ζ-potential using dynamic light scattering on a Zetasizer Nano ZS (Malvern Instruments, Worcestershire, UK); by qualitative elemental composition using an atomic-emission spectrometer iCAP 6300 Radial View (Thermo Fisher Scientific Inc., Waltham, MA, USA) with inductively coupled plasma.…”

To obtain fiber materials with pronounced chemical-biological protection, metal (Zn or Ta) nanoparticles were jointly applied with polyelectrolyte complexes of enzymes and polypeptides being their stabilizers. Computer modeling revealed the preferences between certain polyelectrolyte partners for N-acyl-homoserine lactone acylase and hexahistidine-tagged organophosphorus hydrolase (His6-OPH) possessing the quorum quenching (QQ) behavior with bacterial cells. The combinations of metal nanoparticles and enzymes appeared to function better as compared to the combinations of the same QQ-enzymes with antibiotics (polymyxins), making it possible to decrease the applied quantities by orders of magnitude while giving the same effect. The elimination of Gram-positive and Gram-negative bacterial cells from doubly modified fiber materials notably increased (up to 2.9-fold), whereas His6-OPH retained its hydrolytic activity in reaction with organophosphorus compounds (up to 74% of initially applied activity). Materials with the certain enzyme and Zn nanoparticles were more efficient against Bacillus subtilis cells (up to 2.1-fold), and Ta nanoparticles acted preferentially against Escherichia coli (up to 1.5-fold). Some materials were proved to be more suitable for combined modification by metal nanoparticles and His6-OPH complexes as antimicrobial protectants.

A wide variety of microbiological hazards stimulates a constant development of new protective materials against them. For that, the application of some nanomaterials seems to be very promising. Modification of usual fibers with different metal nanoparticles was successfully illustrated in the work. Tantal nanoparticles have shown the highest antibacterial potency within fibrous materials against both gram-positive (Bacillus subtilis) and gram-negative (Escherichia coli) bacteria. Besides, the effect of tantal nanoparticles towards luminescent Photobacterium phosphoreum cells estimating the general sample ecotoxicity was issued for the first time.
