In this work, AgNPs were synthesized using an anthocyanin extract from Peruvian purple potato INIA 328—Kulli papa. The was obtained through a conventional extraction with acidified ethanolic aqueous solvent. This acted as both reducing and stabilizing agent for the reduction of silver ions. Optimization synthesis parameters, including pH, reaction time, nitrate (AgNO3) concentration, led to optimal formation at pH 10, time 30 min AgNO3 concentration 5 mM. Characterization techniques such X-ray diffraction (XRD) dynamic light scattering (DLS) revealed that had crystallite size 9.42 nm hydrodynamic diameter 21.6 nm, zeta potential −42.03 mV, indicating favorable colloidal stability.

Silver nanoparticles (AgNPs) are widely recognized as a prominent antimicrobial agent and have found applications in the field of medicine. This study focuses on synthesis AgNPs utilizing natural reducing Ceylon olive (Elaeocarpus serratus), presenting an economically viable ecologically friendly approach. For first time, this research demonstrated using phytochemicals extracted from olive, serving both stabilizing agents. The synthesized were characterized with UV–visible spectroscopy, particle size analyzer (PSA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) coupled energy dispersive spectrometer (EDX). spectra primarily indicated formation by surface plasmon resonance band around 434 nm. SEM analysis confirmed presence silver within range 50–110 nm, average approximately 70 FTIR determined that proteins, phenols, flavonoids may acted capping Experimental parameters optimized to improve yield eventually evaluate their antibacterial properties. well diffusion method exhibits significantly larger zone inhibition for Gram-negative bacterial strains (18.4 ± 0.55 mm Pseudomonas aeruginosa 14.4 Escherichia coli) compared Gram-positive (11.6 Staphylococcus aureus 10.4 epidermidis) 50 µg/mL AgNPs. These findings demonstrate potential develop into novel materials bacterial-mediated diseases.

Urinary tract infections (UTIs) are prevalent bacterial in both community and healthcare settings. They account for approximately 40% of all require around 15% antibiotic prescriptions. Although antibiotics have traditionally been used to treat UTIs several decades, the significant increase resistance recent years has made many previously effective treatments ineffective. Biofilm on medical equipment settings creates a reservoir pathogens that can easily be transmitted patients. catheter frequently observed hospitals caused by microbes form biofilm after is inserted into bladder. Managing biofilms challenging due emergence resistance. Biofilms enable evade host’s innate immune defences, resulting long-term persistence. The incidence sepsis spread bloodstream increasing, drug-resistant may even more prevalent. While availability upcoming tests identify cause infection its spectrum critical, it alone will not solve problem; innovative treatment approaches also needed.

Quercetin (QtN) displays low systemic bioavailability caused by poor water solubility and instability. Consequently, it exerts limited anticancer action in vivo. One solution to increase the efficacy of QtN is use appropriate functionalized nanocarriers that preferentially target deliver drug tumor location. Herein, a direct advanced method was designed develop water-soluble hyaluronic acid (HA)-QtN-conjugated silver nanoparticles (AgNPs). HA-QtN reduced nitrate (AgNO3) while acting as stabilizing agent produce AgNPs. Further, HA-QtN#AgNPs served an anchor for folate/folic (FA) conjugated with polyethylene glycol (PEG).
