Abstract

The thermally triggered release of up to 96% of attached uropathogenic E. coli is achieved on two polymers with opposite changes in surface wettability upon reduction in temperature. This demonstrates that the bacterial attachment to a surface cannot be explained in terms of water contact angle alone; rather, the surface composition of the polymer plays the key role.

摘要

在两种聚合物上，温度降低时表面润湿性发生相反变化，可实现高达96%的附着尿路致病性大肠杆菌的热触发释放。这表明细菌在表面的附着不能仅用水接触角来解释；相反，聚合物的表面组成起着关键作用。
