“…Besides, ROS, previous studies claim that interaction of Cr 2 O 3 NPs with fungal hyphae and fungal spores leads to the inhibition of their growth. Significant concentration‐mediated fungicidal assays are reported in previous studies using different fungal strains (Hassan et al, ; Ramesh et al, ) and are consistent with our present RV‐Cr 2 O 3 NPs study.…”

Green synthesis of nanoparticles using plants has become a promising substitute for the conventional chemical synthesis methods. In the present study, our aim was to synthesize chromium oxide nanoparticles (Cr 2 O 3 NPs) through a facile, low-cost, ecofriendly route using leaf extract of Rhamnus virgata (RV). The formation of Cr 2 O 3 NPs was confirmed and characterized by spectroscopic profile of UV-Vis, EDX, FTIR, and XRD analyses. The UV-visible spectroscopy has confirmed the formation of Cr 2 O 3 NPs by the change of color owing to surface plasmon resonance. The bioactive functional groups present in the leaf extract of RV involved in reduction and stabilization of Cr 2 O 3 NPs were determined by FTIR analysis. Based on XRD analysis, crystalline nature of Cr 2 O 3 NPs was determined. The morphological shape and elemental composition of Cr 2 O 3 NPs were investigated using SEM and EDX analyses, respectively. With growing applications of Cr 2 O 3 NPs in biological perspectives, Cr 2 O 3 NPs were evaluated for diverse biopotentials. Cr 2 O 3 NPs were further investigated for its cytotoxicity potentials against HepG2 and HUH-7 cancer cell lines (IC 50 : 39.66 and 45.87 μg/ml), respectively. Cytotoxicity potential of Cr 2 O 3 NPs was confirmed against promastigotes (IC 50 : 33.24 μg/ml) and amastigotes (IC 50 : 44.31 μg/ml) using Leishmania tropica (KMH 23 ). The Cr 2 O 3 NPs were further evaluated for antioxidants, biostatic, alpha-amylase, and protein kinase inhibition properties. Biocompatibility assay was investigated against human macrophages which confirmed the nontoxic nature of Cr 2 O 3 NPs. Overall, the synthesized Cr 2 O 3 NPs are biocompatible and nontoxic and proved to possess significant biopotentials. In future, different in vivo studies are needed to fully investigate the cytotoxicity and mechanism of action associated with these Cr 2 O 3 NPs.

“…Such advantages make metallic NPs obtained by green synthesis (gNPs) prospective for applications in biological analysis, drug delivery and imaging, environmental monitoring, industrial catalysis and electronic devices [11][12][13][14][15][16][17][18][19]. A special role of these gNPs is related to antimicrobial and antibiofilm agents [19][20][21][22][23][24][25].…”

“…Many plants [11,12,21,[24][25][26], algae [4], microorganisms [1,3,[7][8][9][10]14,18,23,[27][28][29][30], as well as redox-imbalanced mammalian cells and systems [31] are known to produce nanostructured mineral crystals and metallic NPs with properties similar to chemically-synthesized materials. Biological agents, including polysaccharides, polypeptides, DNA, enzymes secreted by cells [24,[32][33][34][35][36][37][38][39][40][41] and purified enzymes [42,43] are able to reduce noble metal ions to gain metallic NPs.…”

Novel nanomaterials, including metallic nanoparticles obtained via green synthesis (gNPs), have a great potential for application in biotechnology, industry and medicine. The special role of gNPs is related to antibacterial agents, fluorescent markers and carriers for drug delivery. However, application of gNPs for construction of amperometric biosensors (ABSs) is not well documented. The aim of the current research was to study potential advantages of using gNPs in biosensorics. The extracellular metabolites of the yeast Ogataea polymorpha were used as reducing agents for obtaining gNPs from the corresponding inorganic ions. Several gNPs were synthesized, characterized and tested as enzyme carriers on the surface of graphite electrodes (GEs). The most effective were Pd-based gNPs (gPdNPs), and these were studied further and applied for construction of laccase- and alcohol oxidase (AO)-based ABSs. AO/GE, AO-gPdNPs/GE, laccase/GE and laccase-gPdNPs/GE were obtained, and their analytical characteristics were studied. Both gPdNPs-modified ABSs were found to have broader linear ranges and higher storage stabilities than control electrodes, although they are less sensitive toward corresponding substrates. We thus conclude that gPdNPs may be promising for construction of ABSs for enzymes with very high affinities to their substrates.

“…The intrinsic properties of Cr 2 O 3 has been a subject of intense research over the years . Among other types of chromium oxide NPs, trivalent Cr 2 O 3 is more stable, and is characterized by its increased resistance, hardness and thermodynamic stability . α‐Cr 2 O 3 or Eskolaite is a semiconductor that shows either p‐type or n‐type behavior depending on its growth conditions.…”

We report an eco-friendly synthesis of α-Cr 2 O 3 nanoparticles (NPs) using Callistemon viminalis (Bottle Brush) flower extracts as an efficient reducing and capping agent. NPs of sizes 15 nm and 17 nm were synthesized by annealing them at 400°C and 500°C, respectively, which were characterized by X-ray diffraction, UV-Vis, Fourier transform-infrared, high-resolution-transmission electron microscopy/scanning electron microscopy, SAED, energy-dispersive X-ray spectroscopy and SQUID. Microplate-based assay was used for examining antibacterial potential against 12 pathogenic bacterial strains, and their minimum inhibitory concentrations were calculated. MTT cytotoxic assay was accomplished on Leishmania tropica amastigotes and promastigotes, which revealed IC 50 values of 44 μg/ml and 10.56 μg/ml, respectively. An IC 50 value of 46.32 μg/ml was obtained for HepG2 cancer cells. Enzyme inhibition studies indicated good acetylcholinesterase, moderate butyrylcholinesterase and low alpha-glucosidase inhibition. Hemolytic assay indicated hemocompatibility at low concentration. In addition, good DPPH radical scavenging and moderate reducing power and total antioxidant potential was revealed by α-Cr 2 O 3 NPs.
