| Abstract | This paper presents a smart bioelectrocatalytic immunosensing lab-on-a-chip that uses a novel electrochemical method and can be applied to portable diagnostic systems. Fluid flow in this biochip is induced by capillary attraction force and is controlled by geometrical structure and surface modifications. With this fluid transport mechanism, the biochip does not require external electric power or control parts. Therefore, it is suitable for disposable lab-on-a-chip applications. The fabricated biochip consists of two Polydimethyl-siloxane (PDMS) layers and glass substrate with immunoelectrodes and is 25횞20횞6mm3 in size. |
