“…Selenium is one of the trace essential elements that recently attracted attention due to its antitumor actions, importance in the immune system, and effect on certain hormones such as thyroid hormones [167,168]. To evaluate the antibacterial activity of selenium, Yazhiniprabha and Vaseeharan evaluated the bacteriostatic and larvicidal efficacy of biosynthesized Se-NPs.…”

Based on the recent reports of World Health Organization, increased antibiotic resistance prevalence among bacteria represents the greatest challenge to human health. In addition, the poor solubility, stability, and side effects that lead to inefficiency of the current antibacterial therapy prompted the researchers to explore new innovative strategies to overcome such resilient microbes. Hence, novel antibiotic delivery systems are in high demand. Nanotechnology has attracted considerable interest due to their favored physicochemical properties, drug targeting efficiency, enhanced uptake, and biodistribution. The present review focuses on the recent applications of organic (liposomes, lipid-based nanoparticles, polymeric micelles, and polymeric nanoparticles), and inorganic (silver, silica, magnetic, zinc oxide (ZnO), cobalt, selenium, and cadmium) nanosystems in the domain of antibacterial delivery. We provide a concise description of the characteristics of each system that render it suitable as an antibacterial delivery agent. We also highlight the recent promising innovations used to overcome antibacterial resistance, including the use of lipid polymer nanoparticles, nonlamellar liquid crystalline nanoparticles, anti-microbial oligonucleotides, smart responsive materials, cationic peptides, and natural compounds. We further discuss the applications of antimicrobial photodynamic therapy, combination drug therapy, nano antibiotic strategy, and phage therapy, and their impact on evading antibacterial resistance. Finally, we report on the formulations that made their way towards clinical application.

“…As opposed to conventional chemogenic syntheses, biogenic approaches give rise to thermodynamically stable yet structurally diverse SeNS products in a safe and eco-friendly manner, avoiding the need of post-production treatments [2]. To date, biogenic SeNMs were investigated for their applications in (i) biomedicine, as antimicrobial [19][20][21][22][23][24][25][26][27], anticancer [27][28][29][30][31][32][33][34][35][36][37][38] and antioxidant [27,[39][40][41] agents, due to their high biocompatibility towards eukaryotic in vitro and in vivo systems [22,28,40,42], (ii) photocatalysis, and (iii) biosensing or pollutant adsorption [43][44][45][46], leaving still unveiled the potentiality of these NSs as a bioimaging tool. In particular, the PL properties of SeNPs produced by bacteria just recently began to be explored, as in the case of those recovered from the environmental isolate Stenotrophomonas maltophilia SeITE02 under metabolically controlled growth conditions [6].…”

AbstractVarious technological and biomedical applications rely on the ability of materials to emit light (photoluminescence [PL]), and, among them, metal nanoparticles (NPs) and semi-conductor Quantum Dots (QDs) represent ideal candidates as sensing probes and imaging tools, portraying better PL features than conventional organic dyes. However, the knowledge of PL behavior of semiconductor NPs – i.e., selenium; SeNPs – is still in its infancy, especially for those synthesized by microorganisms. Considering the essential role played by biogenic SeNPs as antimicrobial, anticancer, and antioxidant agents, or food supplements, their PL properties must be explored to take full advantage of them as eco-friendly and versatile tools. Here, PL features of SeNPs produced by the Se-tolerant Stenotrophomonas maltophilia SeITE02 strain, compared with chemogenic ones, are investigated, highlighting the PL dependency on the NP size. Indeed, PL emission shifted from indigo-blue (emission wavelength λem 400–450 nm) to green-yellow (λem 480–570 nm) and orange-red (λem 580–700 nm) for small (ca. 50 nm) and big (ca. 100 nm) SeNPs respectively, revealing the versatility of an environmental bacterial isolate to synthesize diverse PL probes. Besides, biogenic SeNPs show PL lifetime comparable to those of the most used fluorophores, supporting their potential application as markers for (bio)imaging.

BackgroundTo evaluate the antimicrobial and microbicidel activity of B. radicata fermentation broth, the broth was purified by DEAE-cellulose and sephadex LC-20 column. The compounds were submitted to spectral analyses (HPLC, FT-IR, 1D and 2D NMR etc.). ResultsThe purified compounds were identified as the Griseococcin(s) which were naphthoquinone derivatives, the Chemical formula and MW of Griseococcin(1) was determined as C37O10H43N and 661Da. only Griseococcin(1) has good antimicrobial activity among the Griseococcin(s). The zone of inhibition (ZOI), minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) or minimum fungicidal concentration (MFC) of Griseococcin(1) were used to investigate the antimicrobial activity. Antifungal activity of Griseococcin(1) was significant, especially for main pathogenic fungus Trichophyton rubrum and Trichophyton mentagrophytes, MFC/MIC of Griseococcin(1) was 1, while MFC/MIC of postive control was greater than 4, the fungicidal effect of Griseococcin(1) was better than that of positive control.ConclusionsIn this paper, the secondary metabolite compound Griseococcin(1) from B. radicata was purified. The purified compound can restrain main pathogens (T. rubrum and T. mentagrophytes) leading to tinea pedis. The antifungal activity of Griseococcin(1) was similar to that of the positive control and the fungicidal effect of Griseococcin(1) was better than that of positive control, it might be suitable for pharmaceutical industries.
