The variables in controlling the flow of microfluids are voltage and time. This study adopted the method of fast measurements、so time taken for applying voltage did not exceed ten minutes. If voltage is not carefully controlled、the microchannel may be damaged at the particle flow. During measurement、a buffer fluid with a concentration of 0.1 M was used、the current was sufficient to propel the magnetic particles through the microchannel without damage from excessive voltage. The maximal amount of microfluid particles at the junction of the separation and injection channels was obtained with a time of 5 mintures and voltage of 200V.

藉由改变不同的电压和时间来观察颗粒在微流体中的移动情形，由於这个研究是以快速检测为原则，所以将时间控制在10分钟之内；在电压的控制上面如果电压太大的话将会对微流体的管道造成损伤，降低微流体装置的寿命，并且也有可能会对里面的颗粒造成影响，所以缓冲液的浓度使用比较大的0.1 M，这样所产生的电流将足以推动磁性颗粒并且电压不会太大也不会造成管壁的伤害。
