摘要

我们提出了一种聚合物微阀，它允许检测生物聚合物降解而不需要外部能量。这种阀门是基于一个聚合物容器，里面装满了彩色的标记溶液，并由一个薄盖封闭。这种结构被一层聚l -丙交酯薄膜覆盖，生物聚合物的降解触发了视觉检测到的颜色的释放。自主阀具有在各种环境条件下或特定酶下快速测试生物聚合物降解的潜力。

Autonomous valve for detection of biopolymer degradation

We present a polymer microvalve that allows the detection of biopolymer degradation without the need of external energy. The valve is based on a polymer container filled with a colored marker solution and closed by a thin lid. This structure is covered by a film of poly(L-lactide) and degradation of the biopolymer triggers the release of the color which is detected visually. The autonomous valve has potential for the fast testing of biopolymer degradation under various environmental conditions or by specific enzymes.
