In recent years, bacterial infections in hospitals have grown particularly due to the development of antibiotic resistance. Recent research targets the discovery of new antibiotics that exhibit broad spectrum of action without adverse effects or minimizing adverse effects. In this study, the activity of biosynthesized silver nanoparticles against three bacteria commonly found in infectious diseases in the ORL sphere was evaluated. The recorded data revealed an activity comparable to that of the standard antibiotics used in these types of infections, with the observation that the activity of the nanoparticles could also be observed in the particular cases of antibiotic resistance.

In recent years, developing nanoparticles with green processes is gaining huge attention due to its cost-effectiveness, simplicity and non–toxic precursors. The present study utilized the potential of egg white for the synthesis of stable silver nanoparticles (EW-AgNPs). In order to characterize the EW-AgNPs, various techniques have been employed. UV-vis spectroscopy (300-700nm) was used to study the λmax, which highlighted the peak at 422nm. Further, the stability of synthesized EW-AgNPs was studied using Zeta potential, the value of -16.4 mV was obtained, indicating the stability of developed EW-AgNPs in the solution. Transmission electron microscopy was used specifically to visualize the shape and size of synthesized EW-AgNPs, the images showed spherical to the diverse shape of EW-AgNPs. In the first phase, the EW-AgNPs were studied for dye degradation along with NaBH4. The enhanced dye degradation of blue dye was obtained with EW-AgNPs+NaBH4, showing 90- 100% degradation from 100- 25 mgL-1 dye solution, respectively. Further, in the second phase, antimicrobial activity (Zone of Inhibition) of EW-AgNPs was analyzed against Escherichia coli and Staphylococcus aureus. A higher ZOI was obtained for E.coli (16mm) than S. aureus (12.4mm). The present study proved egg white's ability to develop stable silver nanoparticles, which was further found to be effective for blue dye degradation and antimicrobial activity.

Green synthesis of silver nanoparticles using banana sap as a solvent, reducing agent and capping agent is reported in this work. Banana sap has also been used as a binder to incorporate silver nanoparticles into cotton fabric. UV-Visible spectroscopy was used to monitor the quantitative formation of silver nanoparticles. Silver nanoparticle coated fabric showed high antimicrobial activity against gram negative bacteria such asPseudomonas aureginosaandEscherichia coli, and gram positive bacteria such asBacillus subtilisandStaphylococcus aureus.KeywordsGreen synthesis, Silver nanoparticles, banana sap, antimicrobial activity

The antimicrobial bioactivity of silver nanoparticles is well known, and they can be used widely in many applications, becoming especially important in the biomedical industry. On the other hand, the electrospun nanofibers possess properties that can enhance silver nanoparticle applicability. However, silver nanoparticle bioactivity differs depending on the loading of silver ions into electrospun nanofibers. This review is aimed at comparing different silver incorporation methods into electrospun nanofibers and their antimicrobial activity, discussing each procedure’s limitations, and presenting the most promising one. This review showed that the preferred techniques for incorporating silver nanoparticles were direct blending and ultraviolet irradiation methods due to their simplicity and efficient results. Besides, polyacrylonitrile nanofibers (PAN) have been the most reported system loaded with silver nanoparticles. Finally, independently of the technique used, silver nanoparticle-loaded nanofibers show high antimicrobial activity in all cases.
