“…They have been intensively investigated firstly for early applications in xerography (Li & Regensburger, 1963 ; Tang et al, 2006 ) to the current use in X‐ray imaging, photocells, rectifiers, solar cells, photographic exposure meters, pigment and glass production, etc. (Abbaszadeh & Huang, 2020 ; Ho et al, 2021 ; Panahi‐Kalamuei et al, 2015 ). One of the most promising research lines about SeNPs use is focused on their potential role as anti‐tumoral agents in several tumour types including lung, prostate, colorectal, cervical, and breast cancer (Cui et al, 2018 ; Hu et al, 2019 ; Liao et al, 2020 ; Xia et al, 2018 ).…”

Elemental selenium (Se 0 ) nanomaterials undergo allotropic transition from thermodynamically-unstable to more stable phases. This process is significantly different when Se 0 nanoparticles (NPs) are produced via physico-chemical and biological pathways. While the allotropic transition of physico-chemically synthesized Se 0 is fast (minutes to hours), the biogenic Se 0 takes months to complete. The biopolymer layer covering biogenic Se 0 NPs might be the main factor controlling this retardation, but this still remains an open question. Phylogenetically-diverse bacteria reduce selenium oxyanions to red amorphous Se 0 allotrope, which has low market value. Then, red Se 0 undergoes allotropic transition to trigonal (metallic grey) allotrope, the end product having important industrial applications (e.g. semiconductors, alloys). Is it not yet clear whether biogenic Se 0 presents any biological function, or it is mainly a detoxification and respiratory by-product. The better understanding of this transition would benefit the recovery of Se 0 NPs from secondary resources and its targeted utilization with respect to each allotropic stage. This review article presents and critically discusses the main physico-chemical methods and biosynthetic pathways of Se 0 (bio)mineralization. In addition, the article proposes a conceptual model for the resource recovery potential of trigonal selenium nanomaterials in the context of circular economy.

“…Sodium selenite/selenate, selenous acid, and selenium dioxide can be used as precursors for the synthesis of SeNPs added to a "bioreactor"-bacteria or fungi culture fluid, plant extract, etc. [34][35][36]. The precursors' addition to the bioextract leads to the appearance of a red, red-orange, or orange solution color, indicating the reduction of selenium compounds and the formation of colloidal SeNPs.…”

Selenium nanoparticles (SeNPs) are extremely popular objects in nanotechnology. “Green” synthesis has special advantages due to the growing necessity for environmentally friendly, non-toxic, and low-cost methods. This review considers the biosynthesis mechanism of bacteria, fungi, algae, and plants, including the role of various biological substances in the processes of reducing selenium compounds to SeNPs and their further packaging. Modern information and approaches to the possible biomedical use of selenium nanoparticles are presented: antimicrobial, antiviral, anticancer, antioxidant, anti-inflammatory, and other properties, as well as the mechanisms of these processes, that have important potential therapeutic value.

“…Selenium (Se) is an element classified as a semisolid or quasi-solid, and it has peculiar physical and chemical properties, such as superconductivity, high photoconductivity, high reactivity, high piezoelectricity, optical properties, photovoltaic properties, and a relatively low melting point. 216 These properties make selenium a very useful element that is employed in broad areas, such as industrial, medical, environmental, and agricultural fields. Selenium in its elemental form is not biologically active and is insoluble in water due to its redox state.…”
