Efficacy of Gold Nanoparticles against Drug-Resistant Nosocomial Fungal Pathogens and Their Extracellular Enzymes: Resistance Profiling towards Established Antifungal Agents

“…To further confirm the synthesis of AuNPs by M. piperita extract, FTIR was adopted ( Figure 4 ). The FTIR peaks obtained in this study are supported well by previous reports which indicate the possible reducing and encapsulating agents on the AuNPs [ 51 , 52 ]. Extracts from plants of the genus Mentha rich in phenolic acids and essential oils are known to possess antifungal properties and are used as food preservatives [ 53 , 54 ].…”

“…UV-Vis analysis indicates the format per the characteristic wavelength observed around 53 To further confirm the synthesis of AuNPs by M. piperita extract, FTIR was adopted (Figure 4). The FTIR peaks obtained in this study are supported well by previous reports which indicate the possible reducing and encapsulating agents on the AuNPs [51,52]. Extracts from plants of the genus Mentha rich in phenolic acids and essential oils are known To further confirm the synthesis of AuNPs by M. piperita extract, FTIR was adopted (Figure 4).…”

Poly(vinyl alcohol)/Plant Extracts Films: Preparation, Surface Characterization and Antibacterial Studies against Gram Positive and Gram Negative Bacteria

“…Toward 2970–2800 cm −1 , we have found peaks with different intensity (2925 and 2853 cm −1 for Lavandula angustifolia , 2923 and 2850 cm −1 for Mentha piperita , 2919 and 2851 cm −1 for hemp plant ( Cannabis sativa L.), 2920 and 2850 cm −1 for Verbena officinalis and 2922 and 2851 cm −1 for Salvia officinalis ). Their presence was connected with the ν(C–H) stretching vibration of symmetric and asymmetric aliphatic groups [ 43 , 44 , 45 ]. Moreover, the band carbonyl groups ν(C=O) at different peaks (1733 cm −1 for CE, 1709 cm −1 for VE, 1712 cm −1 for ME, 1732 cm −1 for LE, 1728 cm −1 for SE) indicated the presence of monoterpenes such as thujones, camphor, tannins or flavonoid structure [ 46 , 47 , 48 , 49 ].…”

“…The different intensity peaks in the range of 1570 to 1230 cm −1 were assigned to the alkenes and methyl groups [ 42 ]. Furthermore, the large peaks situated in the region 1164–1042 cm −1 (1140 and 1091 cm −1 for CE; 1169 and 1071 cm −1 for VE, 1073 and 1048 cm −1 for ME, 1167 and 1076 cm −1 for LE) emphasize the presence of ν(C-O-C) stretch vibration and ν(C-O) stretch vibration from flavonoids [ 44 , 50 , 51 ]. The highest intensity was found in hemp plant extract ( Cannabis sativa L.).…”

“…Moreover, different functional groups are presented in PVA film loaded with Mentha piperita extract (PVA-ME). The peak that is attributed to phenols and hydrogen-bonded alcohol was shifted toward 3315 cm −1 , and those with a higher intensity corresponded to the ν(C–H) stretching vibration of terpenoids such as menthol were shifted toward 2919, 2851 cm −1 , respectively [ 44 ]. Different changes on the stretching vibration band of carbonyl group ν(C=O) characteristic to the menthol esters and terpenes such as camphor, limonene, carvone and pinene were observed [ 47 ].…”
