Claim 6:
7. A method of making at least one microfluidic valve the valve having a valve diaphragm and a valve seat, the diaphragm and seat each having opposed faces, at least one of the faces comprising surface-activated PDMS, and the opposed faces being arranged such that the diaphragm contacts the seat in at least one position, comprising:
performing repeated make-and-break-contact protocol on the contacting faces of the valve diaphragm and valve seat until the tendency for permanent bonds to form between the contacting faces has been neutralized, thereby enabling the valve diaphragm to perform actuated movements to engage and disengage with the valve seat, without the diaphragm sticking to the valve seat.
