Antibiotic resistance against infections caused by microbes has emerged as a global challenge resulting in longer hospitalizations and higher medical cost mortality. The excessive use of antibiotics led to the swift progression antibiotic bacterial strains. Metallic metal oxide (M/MO) nanoparticles (NPs) have potential provide pertinent alternative they interact with critical cellular organelles biomolecules such DNA, enzymes, ribosomes, lysosomes. This affects permeability cell membrane causing oxidative stress, gene expression, protein activation, enzyme activation restricting habitat microbes. Further, NPs simultaneously target multiple at once making them an efficient antibacterial agent which are unable develop easily, although toxicity associated M/MO still remains key for clinical uses. Green synthesis provides solution reduce toxic effects these it does not harsh chemicals environment NPs. In this work, we provided comprehensive review green using plants (roots, seeds, barks, flowers) (bacteria, fungi, algae). yield achieved from is lower than that conventional methods significant advancements been made recently delineated different mechanism NP interaction their antimicrobial applications discussed detailed. present aims overview current state large-scale well activities.

Abstract Due to their high specific surface area and its characteristic’s functionalized nanomaterials have great potential in medical applications specialty, as an anticancer. Herein, functional nanoparticles (NPs) based on iron oxide Fe 2 O 3 , modified with copper @CuO, tungsten WO were facile synthesized for biomedical applications. The obtained nanocrystal sizes of 35.5 nm 7 25.5 . In addition octahedral square nanoplates 3; respectively. Results revealed that NPs showed remarked anticancer effects versus a safe effect normal cells through cytotoxicity test using MTT-assay. Notably, e.g. our result demonstrated @CuO exhibited the lowest IC 50 value MCF-7 cancer cell line at about 8.876 µg/ml, compared was 12.87 µg/ml 9.211 which indicate modification gave highest antiproliferative against breast cancer. However, these mode toward Vero line, where monitored 40.24 21.13 25.41 NPs. For further evidence. antiviral activity virucidal viral adsorption mechanisms practiced by mechanism prevented virus from replicating inside cells. complete reduction load synergistic combinations between tested two materials instead alone. Interestingly, antimicrobial efficiency NPs, evaluated E. coli, S. aureus, C. albicans pathogens. widest microbial inhibition zone ( ca. 38.45 mm) observed 250 mg/ml coli whereas 40 NPS could form 32.86 mm aureus Nevertheless, relatively resistant all examined superior activities nanostructures might be due unique features accepted evaluations.
