NANOSCALE CALORIMETER ON CHIP AND RELATED METHODS AND DEVICES

摘要

An article comprising: an array of calorimeter devices, wherein the device comprises: at least one fluidic enclosure disposed on a microfluidic chip, wherein the fluidic enclosure is substantially gas impermeable; at least one first chamber and at least one second chamber, wherein the first chamber and the second chamber are disposed within and enclosed by the fluidic enclosure, wherein the first chamber and the second chamber are not vacuum encapsulated; at least two microfluidic channels connected to the first chamber and at least two microfluidic channels connected to the second chamber; and at least one thermal sensor disposed between the chip and the first and second chambers, wherein the thermal sensor is adapted to measure a temperature differential between the first and second chambers. Examples include DSC and TSA devices. Biological binding and melting experiments can be done with high sensitivity.
