“…AgNPs are already used as biomedical additives in bandages, catheters, and in medical garrisons for treating wounds and burns . Similarly, metal oxide NPs showed to be effective in killing a variety of bacterial pathogens responsible for hospital‐acquired infections, even if a higher concentration of this formulation was required as compared to AgNPs to obtain the desired antimicrobial activity …”

“…[29] Similarly, metal oxide NPs showed to be effective in killing a variety of bacterial pathogens responsible for hospital-acquired infections, even if a higher concentration of this formulation was required as compared to AgNPs to obtain the desired antimicrobial activity. [216,217] The mechanisms by which metal-based NPs exert their toxic effects upon pathogenic cells constitute still a black hole of this research field, as several structural parameters of NPs (e.g., composition, surface modification, intrinsic physical properties) can influence their antimicrobial activity. [1] Moreover, the intrinsic biodiversity of the existing pathogenic microorganisms in their genetic arrangement, cell wall structure, and metabolic pathways strongly contributes to increase the complexity in determining the mechanisms of action of metal-based NPs.…”

Bacterial infections are the main cause of chronic infections and even mortality. In fact, due to extensive use of antibiotics and, then, emergence of antibiotic resistance, treatment of such infections by conventional antibiotics has become a major concern worldwide. One of the promising strategies to treat infection diseases is the use of nanomaterials. Among them, mesoporous silica materials (MSMs) have attracted burgeoning attention due to high surface area, tunable pore/particle size, and easy surface functionalization. This review discusses how one can exploit capacities of MSMs to design and fabricate multifunctional/controllable drug delivery systems (DDSs) to combat bacterial infections. At first, the emergency of bacterial and biofilm resistance toward conventional antimicrobials is described and then how nanoparticles exert their toxic effects upon pathogenic cells is discussed. Next, the main aspects of MSMs (e.g., physicochemical properties, multifunctionality, and biosafety) which one should consider in the design of MSM‐based DDSs against bacterial infections are introduced. Finally, a comprehensive analysis of all the papers published dealing with the use of MSMs for delivery of antibacterial chemicals (antimicrobial agents functionalized/adsorbed on mesoporous silica (MS), MS‐loaded with antimicrobial agents, gated MS‐loaded with antimicrobial agents, MS with metal‐based nanoparticles, and MS‐loaded with metal ions) is provided.

“…Alumina (also identified as aluminum(III) oxide) is thermodynamically stable and possesses a corundum-like structure, with hexagonal close-packed structure formed by oxygen atoms with two thirds of the octahedral sites in the lattice filled by Al 31 ions (Martinez Flores et al, 2003). At near-neutral pH, they carry a positive charge on its surface.…”

“…One of the important and usual applications of ZnO nanoparticles is wallpapers in hospitals similar to fungicide and antimicrobials. Because the strong antifungal effect against bacterial pathogens and specific fungi, ZnO (NPs) is also an effective component in producing of dermatophytic lesions to form of antifungal creams, pomades, and lotions [8]. It was reported that superficial fungal infections (SFI) are prevalent skin diseases and affect millions of people worldwide [9].…”

According to the extent of fungal infections, to be chronic these such diseases and recently the emerging issue of increased antibiotic resistance in fungal infections, most of scientists are going to find a proper way to replace antibacterial agent by significant semiconductor ZnO nanoparticles (NPs). They are well known to be one of the most important and special metal oxide nanoparticles in pharmaceutical against the most common fungi. ZnO nanoparticles were synthesized using sol-gel, hydrothermal and functionalized surface methods and formulated in water solutions as nanofluids. XRD, FTIR and SEM techniques and UV-Vis absorbance spectroscopy characterized their ZnO modified nanostructures. Also antimycotic potential according to generally tests such as: (MIC) minimum inhibitory concentration, (MFC) minimum fungicidal concentration and normally well diffusion method with standard strains fungi were performed. Among five common fungi strains using in this research, new various ZnO nanofluids showed noticeable results for dermatophyte fungi like Trichophyton mentagrophytes, Microsporum gypseum, Microsporum canis, Candida albicans and Candid tropicalis which had un growth zones in order 70, 40, 35, 30 and 30 mm in comparing with Clotrimazole reference reagent: 30, 25, 25, 18 and 20 mm by well method. The performance of MIC for ZnO nanofluids on fungi was determined to be equal to 0.35, 3.12, 6.25, 6.25 and 6.25 µgr/ml and MFC of nanoproducts showed the 1.5, 12.5, 25, 25 and 25 µgr/ml. Therefore, the designed ZnO nanofluids could reveal the most effect on fungi which cause dermal (ringworm), mucosal (thrush) and vaginal infections, so we are able to apply these surface high energetic ZnO water-based nanofluid formulations as in vitro nanomedicine and nanohygiene for the first time.
