Claim 11:
12. A method of making at least a portion of at least one microfluidic actuator having a flexible diaphragm portion and an opposite surface portion, the diaphragm and opposite surface each having opposed faces, at least one of the faces comprising surface-activated PDMS, and the opposed faces being arranged such that the opposed faces contact each other in at least one position, comprising:
performing repeated make-and-break-contact protocol on the contacting opposed faces until the tendency for permanent bonds to form between the contacting faces has been neutralized, thereby enabling the diaphragm portion to perform actuated movements to engage and disengage with the opposite surface portion, without the diaphragm sticking to the opposite surface portion.
