Femtosecond laser direct writing bio-gel template for in situ synthesis of nanoparticles

  • 摘要: 为了制备具有可控复杂形状和特定化学性质的聚合物微结构,提出了一种飞秒激光直写生物凝胶模板原位合成纳米粒子的方法。首先,采用飞秒激光直写技术加工带有COOH基团的复杂三维结构的生物凝胶模板,用氢氧化钠处理使COOH基团离子化为COO-基团;然后,用金属盐溶液处理,使金属离子与COO-基团螯合,形成纳米粒子结晶核。通过多次循环盐溶液处理步骤,控制模板中纳米粒子的粒径与含量。实验结果表明:所制备的生物凝胶模板具有亚100 nm分辨率和10 m量级尺寸,纳米粒子含量高达9%。该法简单高效,具有很好的应用前景。
