Abstract: An exemplary system and method for bonding substrate layers in the presence of chemically active species to form functionalized microfluidic surfaces is disclosed as comprising inter alia a first substrate (100), a second substrate (200), a chemically functional species (120) attached to first substrate (100), and a radiatively absorptive mask material (130) disposed substantially between first substrate (100) and second substrate (200). Mask material (130) is suitably adapted to effectively bond first substrate (100) with second substrate (200) upon exposure of the composite structure to radiation of a predetermined, user-selectable wavelength. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve certain device fabrication parameters and/or performance metrics.

Abstract: A microwave device has a monolithic microwave integrated circuit (MMIC) disposed therein for applying microwave radiation to a microfluidic structure, such as a chamber, defined in the device. The microwave radiation from the MMIC is useful for heating samples introduced into the microfluidic structure and for effecting lysis of cells in the samples. Microfabrication techniques allow the fabrication of MMICs that perform heating and cell lysing of samples having volumes in the microliter to picoliter range.
