The AC electrothermal effect can improve the pumping rate by multiple folds compared to other eletrokinetic techniques in micro/nano scale. In this research, the AC electrothermal micropump velocity will be optimized by surface modification using a biocompatible hydrophobic nanocomposite monolayer. This coating will modify the micropump surface to a hydrophobic surface and reduce the friction losses at the liquid-solid interface, and eventually increase the micropumping velocity. The advent of microfabrication and integrated miniature pumps has applications on biomedical devices such as implantable glucose sensors. These micropumps require the transport of small amounts of fluids (μL range). When utilized in biomedical applications, micropumps can be used to administer small amounts of medication (e.g. insulin) at regular time intervals. These micropumps can also be integrated with the lab-on-a-chip devices and can provide inexpensive disposable devices. To demonstrate the fluid manipulation in high conductive bio-fluids, we have developed an optimized AC electrothermal micropump using symmetrical electrode arrays.
