Although not many details are given, it seems to me this people just adapted an existing analytical technology called Capillary Electrophoresis. The piezo pump is a clever addition to the system to improve the micro-liter per second flows typically obtained in CE technology.

I wonder where and how they want to hang the liquid reservoir with the cooling solution. The processor may have to come then with an attached infusion bag like those you get at hospitals.
