Abstract

Micropatterns of silica were generated under biocompatible conditions by a combination of microcontact printing (muCP), layer-by-layer (LbL) self-assembly, and biomimetic silicification. Quaternary amine-containing poly(diallyl dimethyl ammonium chloride) induced polycondensation of silicic acid, resulting in spatioselective formation of silica micropatterns. Scale bar: 10 microm.

摘要

在生物相容条件下，通过微接触印刷（μCP）、层层（LbL）自组装和仿生硅化相结合的方法生成了二氧化硅微图案。含季胺的聚二烯丙基二甲基氯化铵引发硅酸的缩聚反应，从而导致二氧化硅微图案的空间选择性形成。比例尺：10微米。
