Abstract
A valve for use in microfluidic structures. The valve uses a spherical member, such as a ball bearing, to depress an elastomeric member to selectively open and close a microfluidic channel. The valve may be operated manually or by use of an internal force generated to shift the spherical member to its activated position.
