Ultrasonic-assisted green synthesis of silver nanoparticles using Mentha aquatica leaf extract for enhanced antibacterial properties and catalytic activity

Green synthesis of silver nanoparticles using plant extracts and their antimicrobial activities: a review of recent literature

“…145 Recently, an ultra sound-assisted AgNPs of size 8 mm were synthesized using Mentha aquatica leaf extract as reducing and capping agent. 146 To the best of our knowledge, this is the smallest biogenic AgNPs reported so far. The production of NPs could occur at RT, but ultrasound greatly reduced the reaction time to 10 min whereas RT took 1 h. The authors highlighted that the phenolic compounds in the Mentha aquatica leaf extract get oxidized to Quinone in an alkaline condition which provides free electrons for reduction of the Ag + ion to Ag 0 to form the desired AgNPs.…”

Bactericidal Antibacterial Mechanism of Plant Synthesized Silver, Gold and Bimetallic Nanoparticles

“…In our group, we reported the synthesis of spherical AgNPs using the aqueous extract of Combretum erythrophyllum leaf and it was reported to have strong antibacterial activities against Staphylococcus species implicated in dermatological infections [18]. Nouri et al [40] used the aqueous extract of the Mentha aquatica leaf extract to synthesize spherical AgNPs. The results showed the significant effect of the ultrasound during the synthesis to produce smaller AgNPs (8 nm) with enhanced antibacterial activity by lowering the minimum inhibitory concentration (MIC) as compared to those synthesized with the Schematic representation for the green synthesis of metal nanoparticles using different biomolecules.…”

Metal-enhancement study of dual functional photosensitizers with aggregation-induced emission and singlet oxygen generation

“…Plasmonic nanoparticles (NPs) such as gold and silver NPs, have unprecedented ability to localize and enhance their surrounding electric eld and conne it into subwavelength volumes due to the excitation of their surface plasmon resonance (SPR) by the incident electromagnetic eld, leading to several applications from structural color printing, 8,9 energy storage, 10 and catalysis [11][12][13][14] to metal NPs-based biosensors [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] development. More recently, these localised SPR effects have been exploited to enhance the optoelectronic properties of functional materials, such as uorophores and photosensitizers, leading to a new eld of studying metal-enhanced uorescence (MEF) [30][31][32][33][34][35][36][37][38][39][40][41] and singlet oxygen generation (ME-SOG).…”
