Currently, most studies have focused on combining nanomaterial science techniques with the inherent antibacterial activity of inorganic metal oxides [5,6], to develop metal oxide nanoparticles for use as novel antibacterial materials [7,8]. Properties of metal and metal oxide nanoparticles like silver, gold, titanium dioxide as well as magnesium oxide as antimicrobial agents are very well known. Consequently, there is a need of powerful and protective materials for the eradication of diseases.
7 Summary of some mechanisms of action of MONPs in
Over the last few years, interest in silver as an antimicrobial agent has increased in a significant manner.
Properties of metal and metal oxide nanoparticles like silver, gold, titanium dioxide as well as magnesium oxide as antimicrobial agents are very well known.
On the contrary, nanoparticles like zn and zno showed antifungal activity against fungi like penicillium and mucor species. Metal and metal oxide nanoparticles can inhibit bacterial growth by attacking the electronegative phospholipid bilayers of the bacterial cell wall with electropositive metal ions (chandrangsu et al., 2017; In this context, the present review article discusses the toxicity, fate, effects and applications of m/mo nps. In comparison to normal dressings, silver products improve efficacy compared to a standard dressing [25,26].
Synthesized biopolymers are consolidated with.

Metal oxide nanoparticles as antimicrobial agents: They release cations to the anionic sites of the cell membrane and neutralize charges within the cell via electrostatic interaction. Metal oxide nanoparticles as antimicrobial agents:
A promise for the future.
M., sirelkhatim, a., mohamad, d., hasan, h., rahman, r. This review elaborates synthesis methods and antimicrobial mechanisms of various metal as well as metal oxide nanoparticles for better understanding in order to utilize their potentials in. Metal nanoparticles, methods and mechanisms. A promise for the future.
A., antibacterial responses of zinc oxide structures against staphylococcus aureus, pseudomonas aeruginosa and streptococcus.
However, further studies should be performed to minimize the toxicity of metal and metal oxide nanoparticles to apply as proper alternatives for antibiotics and disinfectants especially in biomedical applications. Combination therapy with the metal nanoparticles might be one of the possible strategies to overcome the current bacterial resistance to the antibacterial agents. Iron oxide nanoparticles (ionps) were previously approved by the us food and drug administration (fda) for anemia treatment and studies have also demonstrated its antiviral activity in vitro. Metal/metal oxide nanoparticles (m/mo nps) are powerful agents due to their therapeutic effects in microbial infections.
