Poly(dimethylsiloxane) (PDMS) was selected as the chip material owing to its excellent characters including chemical inertness, low polarity, low electrical conductivity and elasticity.

• 本论文通过紫外光照射的方法使聚二甲基硅氧烷（PDMS）微流控芯片的微通道内壁产生自由基，从而将丙烯酸单体嫁接，再分别通过聚二烯丙基二甲基氯化铵（PDDA）和介孔材料将酶固定在芯片微通道中，实现了蛋白质在PDMS微流控芯片上的酶解。
