“…Surface plasmon resonance (SPR) is a band that occurs on the surface of metallic nanomaterials. Noticeable peaks in the range of 530 to 540 nm correspond to the SPR of AuNPs [ 48 , 49 , 50 ]. UV-Vis analysis indicates the formation of AuNPs by the plant extract as per the characteristic wavelength observed around 530 nm ( Figure 3 ).…”

Drug resistance of filamentous fungi to the commonly used antifungal agents is a major concern in medicine. Therefore, an effective approach to treat several opportunistic fungal infections is the need of the hour. Mentha piperita is used in home remedies to treat different disorders. Isolates of fungi were taken from hospitals in Riyadh, Saudi Arabia, and identified using molecular tools. Amphotericin B, Voriconazole, and Micafungin were applied to screen the resistance of these isolates using both disc and broth microdilution techniques. An aqueous extract of Mentha piperita was utilized to synthesize AuNPs and the nanoparticles were characterized using UV-Vis, FTIR, TEM, EDAX, and XRD. The AuNPs were tested for antifungal activity against the nosocomial fungal pathogens and the activity of extracellular enzymes of such pathogens were analyzed after treatment with AuNPs. We conclude that AuNPs synthesized using Mentha piperita do not possess especially effective antifungal properties against multi-drug resistant Aspergillus species. Five out of eighteen isolates were inhibited by AuNPs. When inhibition was observed, significant alterations in the activity profile of extracellular enzymes of the nosocomial fungi were observed.

In the current investigation, silver/gold nanoparticles (NPs) were synthesized using two methods: chemical and biological, and then characterized colloidal solutions of both NPs using UV-Vis, transmission electron microscopy (TEM) and zeta potential analyzers, X-ray powder diffraction (XRD), and energy dispersive X-ray (EDX) as well as the ToxTrak test for in vitro toxicity and antibacterial activity against Gram-positive bacteria (B. subtilis) and Gram-negative bacteria (E. coli). The plasmon peak of chemical synthesized silver NPs (CH-AgNPs) and gold NPs (CH-AuNPs) was observed at 414 and 530 nm, respectively, while the sharp plasmon peak of biological synthesized silver NPs (Bio-AgNPs) and gold NPs (Bio-AuNPs) was observed at 410 and 525 nm. Under transmission electron microscopy (TEM), the average sizes of CH-AgNPs and CH-AuNPs were 50.56 and 25.98 nm, respectively. Bio-AgNPs and Bio-AuNPs, on the other hand, had average sizes of 25.25 and 16.65 nm, respectively. The stability of NPs was also investigated using the zeta potential. The crystalline structure of AgNPs was confirmed through XRD, and EDX results confirm the element compositions. In the ToxTrak test, the toxic effect value/percentage inhibition (TEV/PI) was calculated. The results showed that CH-AgNPs have the highest TEV/PI value (85.45% for B. subtilis and 83.77% for E. coli) when compared to Bio-AgNPs (55.75% for B. subtilis and 54.42% for E. coli). CH-AuNPs, on the other hand, were 33.51% toxic to B. subtilis and 36.85% toxic to E. coli, compared to Bio-AuNPs, which were 23.36% toxic to B. subtilis and 24.46% toxic to E. coli. The antibacterial activity of Ag/Au NPs was tested and monitored; zone of inhibition (mm in diameter) against B. subtilis and E. coli, with the following pattern emerging: CH-AgNPs (24.80) had the highest antibacterial activity followed by Bio-AgNPs (22.80) < CH-AuNPs (10.60) < Bio-AuNPs (09.00), whereas the control sample (tetracycline antibiotic) revealed a 25.08 mm, zone of inhabitation. Overall, Bio-AgNPs and Bio-AuNPs are the most effective pathogen-killing materials with the lowest toxicity. Our suggestion is that such materials instead of chemical synthesized NPs can be used to coat antibiotic drugs and could be a game-changer for the pharmaceutical industry in terms of effectively controlling the pathogenic bacteria.
