Abstract:
The present invention is an apparatus for providing a linear temperature gradient to an architecture suitable for massively parallel chemical or biochemical processing. The architecture is disposed on a substrate. The apparatus uses two temperature elements disposed essentially parallel to each other and in thermal contact with the substrate. When the temperature elements are held at different temperatures, a linear temperature gradient is formed in the substrate.

Abstract:
The present invention describes a versatile, robust and environmentally controlled platform with a linear temperature gradient for massively parallel chemical or biochemical processing. This apparatus is capable of probing the phase transition behavior of macromolecules in solution, both thermodynamically and kinetically. This includes- but is not limited to- liquid/liquid phase transition behavior of antibody solutions and in situ gelation of thermo-responsive polymers. The device can be operated in a multiplex fashion using a controlled temperature gradient architecture and visualized by dark field microscopy or by other optical intensity measurements.
