Assessment of Antimicrobial Features of Selenium Nanoparticles (SeNPs) Using Cyclic Voltammetric Strategy

Abstract

<jats:p>The emerging biomedical applications of selenium nanoparticles (SeNPs) require facile and efficient strategy to assess its interactions with cell membrane. In this study, an efficient and reproducible microwave assisted method was used to synthesize SeNPs with controllable size distributions. The physical properties of the emergent structures, such as morphology, structure, and size were studied. The antimicrobial applications of SeNPs were assessed by electrochemical analyses that entailed the systematic acquisition of cyclic voltammetry data. Our results demonstrate a straightforward method to predict the integrity of bacterial cell membranes following the administration of SeNP treatments.</jats:p>

Selenium nanoparticles produce a beneficial effect in psoriasis by reducing epidermal hyperproliferation and inflammation

“…The results from PXRD patterns depicts that the SeNPs exhibited sharp diffraction peaks as shown in the Fig. 1 e which demonstrates the crystalline nature of SeNPs and these results are consistent with the previously documented data[ 32 ].

“…Then the excess of NPs was dried, and stained with 2% uranyl acetate for negative stain contrast. After preparation of nanoparticles the UV absorption was measured at 205 nM using UV spectrophotometer by diluting water and dilution ratio was 1:10,000 and for the powder X-ray Diffraction (PXRD) patterns of samples were recorded by using x-ray diffractometer (Philips X’pert MPD System) as per the previous method described [ 32 ]. Samples were illuminated using Ni-filtered Cu-K at current of 30 mA with 40 kV voltages.…”

Fungus-mediated synthesis of Se-BiO-CuO multimetallic nanoparticles as a potential alternative antimicrobial against ESBL-producing Escherichia coli of veterinary origin

“…The distinct peak located at 1,636.40 cm −1 was unambiguously linked to the N–O asymmetric stretching, indicating the active immersion of nitro compounds respectively. Furthermore, the band remarked at 1,055.52 cm −1 could be assigned to the C=C stretching of the broad range alkene group contributing to the synthesis and stability of Se-BiO-CuO MMNPs ( Saeed et al., 2019 ). The x-ray diffraction pattern for CuO, BiO, and Se-NPs was recorded by an x-ray diffractometer in the 2θ range from 20° to 80°.…”

“…XRD peaks with hkl planes (111), (200), (212), and (102) at 2θ corresponds to CuO-NPs (JCPDS: 78-064 8). The additional peaks of Se-NPS (JCPDS 06-0362) and BiO-NPs (JCPDS card 06-0249) were obtained at the planes (101), (002), (100), (110), and (112), respectively ( Saeed et al., 2019 ; Zhao et al., 2017 ). The average size of Se-BiO-CuO MMNPs was 66 nm employing Scherer’s equation as shown in Figure 4D .…”
