水泵：聚离子复合物（PIC）囊泡是由PIC微滴自发形成的，PIC微滴是通过混合阳离子和阴离子聚合物形成的（见图片）。形成过程可以通过用聚焦的红外激光局部加热来可逆地控制，该激光触发微相分离和随后的水流入。所得到的巨大单层囊泡的大小由PIC液滴的初始大小决定。
Water pump: Polyion complex (PIC) vesicles are spontaneously formed from PIC microdroplets, which are formed by mixing cationic and anionic polymers (see picture). The formation process can be reversibly controlled by local heating with a focused infrared laser that triggers microphase separation and subsequent water influx. The size of the resulting giant unilamellar vesicles is determined by the initial size of the PIC droplets.
