N-Isopropylacrylamide-co-acrylamidophenylboronic acid (NIPAM-co-PBA) microgels were prepared by free radical polymerization in water. The release of glucose and Alizarin Red S (ARS) from the microgels as a function of temperature has been investigated by using laser light scattering (LLS) and ultrasensitive differential scanning calorimetry (US-DSC). Such microgels can bind glucose and ARS via boronic acids at a lower temperature. As the temperature increases, the microgels shrink, and the diols are released. The release could be controlled by temperature. The effect of the structure of the microgels on the release is also discussed.
通过在水中进行自由基聚合制备了N-异丙基丙烯酰胺-共-丙烯酰胺基苯硼酸（NIPAM-co-PBA）微凝胶。利用激光散射（LLS）和超灵敏差示扫描量热法（US-DSC）研究了微凝胶中葡萄糖和茜素红S（ARS）的释放量随温度的变化情况。此类微凝胶在较低温度下可通过硼酸与葡萄糖和ARS结合。随着温度升高，微凝胶收缩，二醇被释放出来。释放过程可由温度控制。还讨论了微凝胶结构对释放的影响。
