Biogenic silver nanoparticles from chamomile incorporated in hydrogels for high transparent non-infectiveness contact lenses.

ABSTRACT: Chamomile extract (CHA) was employed in the synthesis of silver nanoparticles (AgNPs(CHA)). These nanoparticles were incorporated into a hydroxyethyl methacrylate (pHEMA) matrix during polymerization at concentrations of 1 mg/mL (pHEMA@AgNPs(CHA)_1) and 2 mg/mL (pHEMA@AgNPs(CHA)_2). The resulting materials- AgNPs(CHA), pHEMA@AgNPs(CHA)_1, and pHEMA@AgNPs(CHA)_2 -were characterized using a plethora of analytical techniques, including Refractive Index (RI), X-ray fluorescence (XRF) spectroscopy, X-ray powder diffraction (XRPD), thermogravimetric-differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), ultraviolet-visible (UV-Vis) spectroscopy, and attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy in the solid state, as well as UV-Vis spect
