溶胶-凝胶传感器 溶胶-凝胶工艺是一种大约 150 年前首次报道的陶瓷材料生产方法，现在重新引起人们的兴趣 (1-4)，因为它提供了一种将热敏材料（包括有机分子和活性蛋白质）融入多孔陶瓷基质的便捷方法。溶胶-凝胶技术的相对（有时是误导性的）简单性至少也是其快速扩散的部分原因。无机载体，特别是二氧化硅基基质，与有机聚合物载体相比具有多种优势，包括物理刚性和高耐磨性；在水溶液和有机溶液中的膨胀可忽略不计；化学惰性（与分析物的相互作用低，不可逆副反应导致的中毒速度较慢）；高生物降解性、光化学稳定性和热稳定性；以及优异的光学透明度和低固有荧光。
Sol-Gel Sensors he sol-gel process, a method for the production of ceramic materi-als that was first reported some 150 years ago, is gaining renewed interest (1-4) because it provides a convenient way to incorporate heat-sensitive materials, including organic molecules and ac-tive proteins, in porous ceramic matri-ces. The relative (and sometimes mislead-ing) simplicity of sol-gel technology is also at least partially responsible for its rapid proliferation.Inorganic supports, particularly silicabased matrices, offer several advantages over organic polymer supports, including physical rigidity and high abrasionresistivity; negligible swelling in both aque-ous and organic solutions; chemical inert-ness (low interaction with analytes and slower poisoning by irreversible side reac-tions); high biodegradational, photo-chemical, and thermal stability; and excel-lent optical transparency and low intrin-sic fluorescence.
