Gold nanoparticle-Enhanced Bioglass: Unveiling <i>In Vitro</i> and <i>In Vivo</i> Bioactivity Characteristics for Advanced Medical Applications
Abstract
<jats:p>Incorporated gold ions Au into glass with composition 30P<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub>–20Ca(OH)<jats:sub>2</jats:sub>–20ZnO-8.0KF-5B<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>–2.0TiO<jats:sub>2</jats:sub> in mol% with 400 ppm (Gold III Chloride trihydrate HAuCl<jats:sub>4</jats:sub>–3H<jats:sub>2</jats:sub>O) and 600 ppm(Gold III Chloride trihydrate HAuCl<jats:sub>4</jats:sub>–3H<jats:sub>2</jats:sub>O) by using terdiurnal method quenching method. The present glass’s Vicker microhardness, Hv, was determined together with X-ray diffraction (XRD) and differential thermal analysis (DTA). Utilizing a transmission electronmicroscope (TEM) and a scanning electron microscope (SEM), the gold nanoparticle and microstructure of these glasses were examined. According to the SEM photographs the heat treatment method significantly changed the form of the crystals phase of produced glass-ceramic. The glass-doped Auwas verified by TEM to be nanocrystalline, with a spherical form and varying sizes between 14.7 and 16.2 nm. Investigations have been carried out into the bioactivity of the produced glass, including its antibacterial, anti-proliferative/cytotoxic properties against both normal and activatedsplenic cells <jats:italic>In Vitro</jats:italic>, and anticancer effects. These findings demonstrated the strongest antibacterial activity against both Gram positive and Gram negative bacteria as well as fungi in the glass doped with 600 parts per million of Au ions. It also demonstrated anti-proliferative/cytotoxicityagainst normal splenic cells, but had the maximum level of neither cytotoxicity nor proliferative effects on activated splenic cells. According to the data, these produced glasses show promise as possibilities for many medical applications.</jats:p>
