Abstract
A flexible microfluidic device, including a first substrate having micro-rough microchannels therein, a second substrate having electrodes thereon, and a bonding layer securing the second substrate to the first substrate. Alternatively, one or more bonding surfaces of the first and second substrate are treated to increase bonding activity, and are bonded together. To manufacture the device, a microchannel mold is formed and placed in a mold cavity to create a master mold. A curable polymeric material is added to the mold cavity and cured to form the first substrate. Electrodes are printed on the second substrate. A bonding layer is coated on the first or second substrate, the substrates are aligned, and the bonding layer is cured. Alternatively, the bonding surfaces of the first and/or second substrate are subjected to treatment to increase bonding activity, the substrates are aligned, and permitted to bond.
