  • The Antimicrobial Activities of Silver Nanoparticles Synthesized from Medicinal Mushrooms. [Journal Article]
    Int J Med Mushrooms. 2020; 22(9):869-883.Klaus A, Petrovic P, … Van Griensven LJLD
  • Crude polysaccharide extracts derived from Agaricus bisporus (A), A. brasiliensis (B), and Phellinus linteus (P) were used for the synthesis of silver nanoparticles (AgNPs, labeled AAgNP, BAgNP, PAgNP, respectively). UV and FT-IR spectra, size distribution, and zeta potential of the respective particles were recorded, and TEM and SEM-EDS characterization was done. UV-Vis spectroscopy showed maxim…
  • Comparative Analysis of Commercial Colloidal Silver Products. [Journal Article]
    Int J Nanomedicine. 2020; 15:10425-10434.Kumar A, Goia DV
  • CONCLUSIONS: The results of this evaluation show clearly that 70% of the commercial products evaluated contain only ionic silver. Despite the evidence showing that silver nanoparticles are not present, eight of these products are promoted by the manufacturers as 'colloidal silver'. Considering the extensive scientific research showing major differences between silver ionic and silver nanoparticles in terms of mechanisms of action, efficacy and safety, it is clear that this misrepresentation impacts the consumers and must be addressed. This study serves as blueprint for a scientific protocol to be followed by manufacturers for characterizing their silver supplements.

  • Potent antiviral effect of silver nanoparticles on SARS-CoV-2. [Journal Article]
    Biochem Biophys Res Commun. 2020 11 26; 533(1):195-200.Jeremiah SS, Miyakawa K, … Ryo A
  • The pandemic of COVID-19 is spreading unchecked due to the lack of effective antiviral measures. Silver nanoparticles (AgNP) have been studied to possess antiviral properties and are presumed to inhibit SARS-CoV-2. Due to the need for an effective agent against SARS-CoV-2, we evaluated the antiviral effect of AgNPs. We evaluated a plethora of AgNPs of different sizes and concentration and observe…
  • Migration study of organotin compounds from food packaging by surface-enhanced Raman scattering. [Journal Article]
    Talanta. 2020 Dec 01; 220:121408.Mandrile L, Vona M, … Rossi AM
  • The potential of surface-enhanced Raman scattering (SERS) has been investigated for the rapid analysis of two representative organotin compounds (OTCs): dibutyltin maleate (DTM) and tributyltin chloride (TBT), after migration tests from polyvinyl chloride (PVC), as a model food packaging material in aqueous food simulant (acetic acid 3% w/v). OTCs, often used as heat stabilizers additives for PVC…
  • Facile preparation of nanoparticle based SERS substrates for trace molecule detection. [Journal Article]
    Phys Chem Chem Phys. 2020 Sep 30; 22(37):21139-21146.Demirtaş Ö, Doğanay D, … Bek A
  • In this work, we demonstrate that a polished Si wafer surface can be converted to possess strong surface-enhanced Raman scattering (SERS) activity by spray coating of polyol synthesized colloidal silver nanoparticles (AgNPs) at as low as 1% surface coverage. The SERS activity assays of substrate surfaces prepared with different production procedures (spray and spin coating) at different surface c…
  • Fumaric acid incorporated Ag/agar-agar hybrid hydrogel: A multifunctional avenue to tackle wound healing. [Journal Article]
    Mater Sci Eng C Mater Biol Appl. 2020 Jun; 111:110743.Basha SI, Ghosh S, … Sukumar E
  • Wound and its treatment is one of the major health concerns throughout the globe. Various extrinsic and intrinsic factors can influence the dynamics of healing mechanism. One such extrinsic factor is moist environment in wound healing. The advantages of optimum hydration in wound healing are enhanced autolytic debridement, angiogenesis and accelerated cell proliferation and collagen formation. Bu…
  • New Generation of Antibacterial Products Based on Colloidal Silver. [Journal Article]
    Materials (Basel). 2020 Mar 29; 13(7)Pascu B, Negrea A, … Duteanu N
  • The main objective of the present paper is the green synthesis of colloidal silver by ultrasonication starting from silver nitrate and using soluble starch as the reducing agent. Soluble starch has been used during synthesis because it is a cheap and environmentally friendly reactive. Silver colloid has been characterized by physicochemical methods: UV-VIS spectroscopy, Scanning Electron Microsco…
  • Antibacterial activity of iron oxide, iron nitride, and tobramycin conjugated nanoparticles against Pseudomonas aeruginosa biofilms. [Journal Article]
    J Nanobiotechnology. 2020 Feb 18; 18(1):35.Armijo LM, Wawrzyniec SJ, … Osiński M
  • CONCLUSIONS: Positive inhibition is reported for uncapped and alginate-capped iron-oxide NPs, and the corresponding MICs are presented. We report zero susceptibility to iron-oxide NPs capped with polyethylene glycol, suggesting that the capping agent plays a major role in enabling bactericidal ability in of the nanocomposite. Our findings suggest that the alginate-coated nanocomposites investigated in this study have the potential to overcome the bacterial biofilm barrier. Magnetic field application increases the action, likely via enhanced diffusion of the iron-oxide NPs and NP-drug conjugates through mucin and alginate barriers, which are characteristic of cystic-fibrosis respiratory infections. We demonstrate that iron-oxide NPs coated with alginate, as well as alginate-coated magnetite-tobramycin conjugates inhibit P. aeruginosa growth and biofilm formation in established colonies. We have also determined that susceptibility to tobramycin decreases for longer culture times. However, susceptibility to the iron-oxide NP compounds did not demonstrate any comparable decrease with increasing culture time. These findings imply that iron-oxide NPs are promising lower-cost alternatives to silver NPs in antibacterial coatings, solutions, and drugs, as well as other applications in which microbial abolition or infestation prevention is sought.
  • Mass Spectrometric Assay of Alpha-Fetoprotein Isoforms for Accurate Serological Evaluation. [Journal Article]
    Anal Chem. 2020 04 07; 92(7):4807-4813.Li Z, Li H, … Lv Y
  • Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death, which is demanding powerful diagnosis tools. Although the traditionally used serological biomarker alpha-fetoprotein (AFP) cannot meet the requirement of accurate diagnosis, its isoform alpha-fetoprotein L3 (AFP-L3) ratio in total AFP is emerging as a highly specific alternative. The routine electrophoretic blott…

    Antibiotics (Basel). 2020 Jan 19; 9(1)Vila Domínguez A, Ayerbe Algaba R, … Smani Y
  • Due to the emergence of antimicrobial resistance, new alternative therapies are needed. Silver was used to treat bacterial infections since antiquity due to its known antimicrobial properties. Here, we aimed to evaluate the in vitro activity of colloidal silver (CS) against multidrug-resistant (MDR) Gram-negative and Gram-positive bacteria. A total of 270 strains (Acinetobacter baumannii (n = 45)…
