“…In this study we proposed an original procedure for the microwave-assisted synthesis of silver nanostars by involving trisodium citrate as a reducing and stabilizing agent of

ions. The role of microwave heating is to create a more homogenous thermal environment for the synthesis procedure and to speed up the process as shown in literature [ 9 ]. Once the synthesis procedure was completed, the nanostars’ morphology was analyzed by microscopic complementary techniques (TEM/STEM, AFM).…”

We report a very simple, rapid and reproducible method for the fabrication of anisotropic silver nanostars (AgNS) that can be successfully used as highly efficient SERS substrates for different bioanalytes, even in the case of a near-infra-red (NIR) excitation laser. The nanostars have been synthesized using the chemical reduction of Ag+ ions by trisodium citrate. This is the first research reporting the synthesis of AgNS using only trisodium citrate as a reducing and stabilizing agent. The key elements of this original synthesis procedure are rapid hydrothermal synthesis of silver nanostars followed by a cooling down procedure by immersion in a water bath. The synthesis was performed in a sealed bottom flask homogenously heated and brought to a boil in a microwave oven. After 60 s, the colloidal solution was cooled down to room temperature by immersion in a water bath at 35 °C. The as-synthesized AgNS were washed by centrifugation and used for SERS analysis of test molecules (methylene blue) as well as biological analytes: pharmaceutical compounds with various Raman cross sections (doxorubicin, atenolol & metoprolol), cell lysates and amino acids (methionine & cysteine). UV-Vis absorption spectroscopy, (Scanning) Transmission Electron Microscopy ((S)TEM) and Atomic Force Microscopy (AFM) have been employed for investigating nanostars’ physical properties.

Silver nanoparticles (AgNPs) have been employed in various fields of biotechnology due to their proven properties as an antibacterial, antiviral and antifungal agent. AgNPs are generally synthesized through chemical, physical and biological approaches involving a myriad of methods. As each approach confers unique advantages and challenges, a trends analysis of literature for the AgNPs synthesis using different types of synthesis were also reviewed through a bibliometric approach. A sum of 10,278 publications were analyzed on the annual numbers of publication relating to AgNPs and biological, chemical or physical synthesis from 2010 to 2020 using Microsoft Excel applied to the Scopus publication database. Furthermore, another bibliometric clustering and mapping software were used to study the occurrences of author keywords on the biomedical applications of biosynthesized AgNPs and a total collection of 224 documents were found, sourced from articles, reviews, book chapters, conference papers and reviews. AgNPs provides an excellent, dependable, and effective solution for seven major concerns: as antibacterial, antiviral, anticancer, bone healing, bone cement, dental applications and wound healing. In recent years, AgNPs have been employed in biomedical sector due to their antibacterial, antiviral and anticancer properties. This review discussed on the types of synthesis, how AgNPs are characterized and their applications in biomedical field.

Sustainability has become a global requirement in all industries. In the textile sector sustainability can be achieved by developing innovative techniques, approaches, and machinery. The current study introduces a sustainable approach for linen dyeing with natural lac dye using microwave heating after the treatment with chitosan as a cationic bio-mordant. The chitosan treatment was carried out by a pad/dry-cure process with citric or acetic acid. Linen samples were characterized by scanning electron microscopy (SEM), and fourier transform infrared spectroscopy (FTIR). The results confirmed the deposition of chitosan on linen fabric with both citric and acetic acid. X-ray diffraction (XRD) was used to determine the change in the crystallinity of linen fabric after chitosan treatment and lac dyeing. The color strength results confirmed the successful application of chitosan as a bio-mordant and the efficiency of microwave heating in shortage the dyeing period in lac dyeing, where the K/S increased from 1.54 to reach 18.86 and 13 with acetic and citric acid, respectively in 7 min. Furthermore, the maximum color strength was achieved at pH 3 of lac dye and the presence of chitosan eliminated the usage of salt in the lac dyeing of linen fabrics. Fastness properties of the lac dyed linen fabrics to wash, light, and perspiration have been discussed. The functional properties (antibacterial activity and UV protection) of linen fabrics were assessed. The antibacterial activity was decreased after the chitosan-treated linen samples were dyed with lac dye. However, the UPF of linen samples was enhanced after lac dyeing.
