Surface modification of biomedical implants is an established strategy to improve osseointegration. TiO2 nanoflowers (TNF) were deposited on a titanium substrate by hydrothermal technique followed by microwave radiation at 700 W for 5–15 min. Microwave-treated samples were analyzed by X-ray diffraction (XRD), scanning electron microscopy, and Raman spectroscopy to determine their physicochemical characteristics. The XRD and Raman results showed crystalline rutile TiO2. The surfaces of microwave-treated TNF were hydrophilic with split hierarchical structure. The Sips isotherm was used to analyze BSA adsorption on microwave treated TNF samples. The microwave treatment enhances protein adsorption capacity.

生物医学植入物的表面改性是改善骨整合的既定策略。TiO 2纳米花(TNF)通过水热技术沉积在钛基底上,然后在 700 W 下微波辐射 5-15 分钟。通过 X 射线衍射 (XRD)、扫描电子显微镜和拉曼光谱分析微波处理的样品,以确定它们的理化特性。XRD和拉曼结果显示结晶金红石TiO 2。微波处理的 TNF 表面是亲水的,具有分层结构。Sips 等温线用于分析微波处理过的 TNF 样品上的 BSA 吸附。微波处理增强了蛋白质吸附能力。
