Abstract
A microfluidic biochip for detecting disease antigens using gold nano interdigitated electrode circuit under a controlled self-driven flow condition is disclosed. The biochip incorporates hydrophilic microchannels for controlled self-driven flow and gold nano interdigitated electrodes for capacitive sensing with enhanced sensitivity. The biochip's microchannel has a surface treated with oxygen plasma to control microchannel surface hydrophilicity and flow rate of the biofluid sample. Carbon Nanotubes (CNTs) are utilized as an intermediate layer to enhance the binding capability to nano electrodes to enhance sensitivity. Due to the carboxylic groups of the CNTs, covalent bond binding between the antibodies and the CNTs allows the antibodies to adhere more readily on the surface of the electrodes. The quantity of antibodies attaching to the surface is increased due to the high surface to area ratio in CNTs.
