Low fluorescent adhesives serve as critical bonding tools.

Low autofluorescent adhesives reduce the possibility of undesirable background fluorescence in microfluidic devices. Adhesives Research Inc. (Glen Rock, PA; 717/235-7979) has developed the adhesives to provide minimal fluorescence and good assay compatibility. Used alone or in conjunction with an assay platform, the adhesives will adhere to the base plate without creating voids or gaps, and will not flow into microfluidic channels or interfere with chemical reagents used in the microchannels and reservoirs. The adhesives are dimensionally stable, provide resistance to moisture and temperature, and are chemically compatible with electrophoretic separation. These clear adhesives can be either flexible or rigid, and can incorporate hydrophilic properties to enhance the flow of liquid through microfluidic channels.
