Summary: The use of natural reducing and capping agents in environmentally sustainable synthesis of nanoparticles (NPs) has gained importance. Honey has emerged as a promising agent in the synthesis of metal and metal oxide NPs, serving as both a stabilizing and reducing agent. This review focuses on honey-mediated synthesis of silver NPs (Ag-NPs) and zinc oxide NPs (ZnO-NPs), highlighting its role as a reducing and capping agent, and provides a comprehensive examination of bio-based reducing and capping/stabilizing agents. The review also discusses environmentally friendly methods for NP synthesis.

Summary: In this study, the stability and antibacterial activity of silver nanoparticles (AgNPs) coated with different stabilizers were investigated. The AgNPs showed differences in stability and size change depending on the coating agent used. The stabilizer may function as a growth controller of the nanoparticles, affecting their biological properties. The protective or stabilizing agents also played a role in the antibacterial capacity and stability of AgNPs over time.

Summary: Food spoilage leads to increased carbon dioxide emissions and food processing demand. This study developed anti-bacterial coatings using inkjet printing of silver nano-inks on food-grade polymer packaging, aiming to enhance food safety and reduce spoilage. Silver nanoparticles were synthesized and characterized, and all silver nanoparticles showed strong antibacterial activity against E. coli. The printed silver nano-inks on polymer reduced the bacterial cell population, and the bactericidal performance was comparable to penicillin-coated polymer. Ecotoxicity testing on daphniids showed the impact on freshwater environment.

Summary: This manuscript describes the one-step eco-friendly green fabrication of silver nanoparticles (AgNPs) through in-situ bio-reduction of silver nitrate using Syzygium aromaticum leaf extract. The UV-vis spectroscopy showed a characteristic SPR peak around 442 nm. FTIR spectroscopy confirmed the presence of bioactive phyto-molecules on the AgNPs. TEM images revealed oval and spherical particles with a mean diameter of 12.6 nm. XRD analysis confirmed the crystalline structure of the AgNPs. The phytosynthesized AgNPs exhibited broad-spectrum antimicrobial activity against two foodborne pathogenic bacteria, Listeria monocytogenes and Staphylococcus aureus, and effectively inhibited biofilm formation.

Summary: This study investigated the antimicrobial and cytotoxicity effects of silver nanoparticles (AgNPs) synthesized using different reducing agents. The results showed that AgNPs synthesized using gum arabic had higher bactericidal activity and non-selective cytotoxicity towards normal and cancer cells. AgNPs synthesized using other reducing agents had insignificant antimicrobial activity and cytotoxicity at certain concentrations.

Summary: The present study synthesized silver nanoparticles (Ag NPs) using a methanolic and aqueous extract of R. stricta. The Ag NPs were characterized using UV-visible spectroscopy, EDX, FESEM, and FTIR techniques. The Ag NPs exhibited SPR at 490-560 nm in the UV-visible spectra, and FTIR spectrum indicated the presence of various functional groups capping the nanoparticles. The Ag NPs had an average size of 20-35 nm and a spherical shape as confirmed by FESEM. The Ag NPs showed superior antioxidant, antibacterial, and antifungal activities compared to the plant extract.

Summary: In an attempt to address the limitations of the currently available marketed formulation of exemestane, a study was conducted using a lamellar liquid crystal based formulation for topical application. Results showed that the formulation exhibited gel-like properties at low shear rate, transitioning to a flowing liquid at higher shear rate. This alternative route of drug delivery may offer improved bioavailability of exemestane due to enhanced solubility, permeability, and absorption.

Summary: TiO2 synthesized through reverse micelle sol-gel (RMS) route exhibited a mean diameter of 18 nm and a homogenous particle distribution, with a bandgap of 3.15 eV and showed high degradation efficiency under visible LED light towards levofloxacin (LFX) aqueous pollutant. The visible light photoactivity of TiO2 was mainly attributed to ligand to metal charge transfer (LMCT) process.

Summary: The study investigated the degradation performance of Cu-TiO2 nanomaterials towards levofloxacin (LFX) antibiotic under a visible LED light source. Optimum photocatalytic degradation of 75.5% was achieved by 0.5 wt% Cu-TiO2 under 6 h. of visible light exposure. Formation of copper-LFX complexes in higher Cu-doped TiO2 samples, involving Cu2+, might have hindered the photocatalytic activity.

Summary: Lipoteichoic acid (LTA) from Bacillus subtilis was found to self-assemble into spherical micelles in aqueous solution and exhibit adsorption behavior at the solid-liquid interface. The presence of calcium chloride (CaCl2) influenced the size and structure of LTA micelles, while also promoting LTA adsorption at the SiO2-water interface. This study provides valuable insights into the self-assembly behavior of LTA and its role in bacterial adhesion.
