Abstract:
PROBLEM TO BE SOLVED: To provide devices that can be utilized to conduct a variety of nucleic acid amplification reactions, while having sufficient versatility for use in other types of analyses as well.SOLUTION: An M×N matrix microfluidic device for performing a matrix of reactions is disclosed. This device (100) has a plurality of reaction cells (106) in communication with one of either a sample inlet (120) or a reagent inlet (124) through a via formed within an elastomeric block of the device. Methods provided include a method for forming vias in parallel in an elastomeric layer of the microfluidic device. The method includes a step of using patterned photoresist masks and a step of etching regions or portions of an elastomeric layer of the elastomeric block.

An M x N matrix microfluidic device for performing a matrix of reactions, the device (100) having a plurality of reaction cells (106) in communication with one of either a sample inlet (120) or a reagent t inlet (124) through a via formed within an elastomeric block of the device. Methods provided include a method for forming vias in parallel in an elastomeric layer of an elastomeric block of a microfluidic device, the method includes using patterned photoresist masks and etching reagents to etch away regions or portions of an elastomeric layer of the elastomeric block.
Abstract:
New microfluidic devices, useful for carrying out chemical reactions, are provided. The devices are adapted for on-chip solvent exchange, chemical processes requiring multiple chemical reactions, and rapid concentration of reagents.
Abstract:
The present invention is directed to a surface modified polymer comprising a surface which is covalently bonded to a surface modifying compound. Formation of the covalent bond between the polymer and the surface modifying compound is achieved by a reaction between an intrinsic functional group that is present in the polymer and the functional group of the surface modifying compound. By using a polymer having an intrinsic functional group, a separate surface activation step is avoided.
