Micro-chemical system can be divided into four sub-systems, i. e. micro-heat system, micro-reaction system, micro-separation system and micro-analysis system.
微化工系统通常包括了微热系统、微反应系统、微分离系统和微分析系统。

However, they are usually synthesized as nano-sized or micro-sized powders, and this makes it very difficult to retrieve them from the mother liquors or the liquid-phase reaction systems [2, 3].
然而，他们常常是纳米或微米粉末，这使他们很难从母液或作用体系的液相中分离出来[2]。

The third part is to use the sputtering, photolithography to produce heaters and temperature sensors which heat the reactionmicro chamber and provide the temperature condition for the PCR reaction.
