1. A microfluidic valve system comprising a matrix, a hydrophilic acceptor region, a hydrophilic transfer region, and a hydrophobic gap between the acceptor region and the transfer region, wherein said system further includes a wetting fluid that when added to the transfer region, solubilizes a transfer agent at the hydrophilic transfer region and permits the wetting fluid to span the hydrophobic gap to the hydrophilic acceptor region.
