Multifunctional iron oxide nanoparticles using Carica papaya fruit extract as antibacterial, antioxidant and photocatalytic agent to remove industrial dyes

Green Synthesis of Gold Nanoflowers Using Rosmarinus officinalis and Helichrysum italicum Extracts: Comparative Studies of Their Antimicrobial and Antibiofilm Activities

“…Small NPs have a better chance of entering the bacterial membrane due to their relatively larger surface-to-volume ratio, hence displaying stronger antimicrobial activity [ 24 , 81 , 88 , 91 , 93 ]. Furthermore, the antibacterial activity of both AuNFs was concentration-dependent similar to the earlier reports [ 89 , 91 , 94 , 95 ]. Bacterial cells underneath in the biofilm are 1000-fold more resistant to antibacterial agents than planktonic cells, hence the disruption of preformed mature biofilm is quite difficult [ 96 ].…”

“…To date, several studies have demonstrated the antimicrobial and antibiofim activity of different nanomaterials, such as silver, gold, copper, zinc, iron, and magnesium oxide [ 20 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 ]. Furthermore, gold nanomaterials have attracted tremendous attention in fighting against the pathogens due to unique properties such as size, shape, surface and optical properties, low toxicity, ease of synthesis, and high stability [ 21 , 81 ].…”

Nanomedicine for drug resistant pathogens and COVID-19 using mushroom nanocomposite inspired with bacteriocin – A review

“…In particular, silver, gold, zinc, and their compounds fruitfully inactivate many pathogenic microorganisms. Currently, tetracycline hydrochloride development in polymeric NPs has demonstrated increased antimicrobial properties and anti-methicillin resistant Staphylococcus aureus (MRSA) properties with non-polymerized forms of penicillin and N-methylthio β-lactams [165] , [166] , [167] . Vancomycin-capped Au NPs have also revealed increasing antimicrobial properties against vancomycin-resistant enterococci (VRE), and E. coli strains [168] .…”

Formulation and evaluation of azithromycin-loaded silver nanoparticles for the treatment of infected wounds

“…In nanoscience and technology, green synthesis offers several advantages. Using non-toxic diluters and sustainable ingredients which contain polyphenols or flavonoids that are essential for producing and processing nanoparticles, which calls for the adoption of environmentally friendly methods with no need to culture preparation or maintenance, no isolation, and economical and safe method ( Krishnamoorthi et al, 2022 ; Malaikozhundan et al, 2022a ; Malaikozhundan et al, 2022b ; Malaikozhundan et al, 2020 ; Saddik et al, 2020b ; Saddik et al, 2022b ; Senthamarai and Malaikozhundan, 2022 ). Ag NPs were produced en v ironmentally by using a variety of plant components ( Malaikozhundan et al, 2016 ; Malaikozhundan et al, 2017 ).…”
