Patent number: 7086277Abstract: A device having a flow channel, wherein a layer of mesh is adhered to a surface forming a wall of a flow channel, but the layer of mesh is of such dimensions that the layer of mesh does not contact those portions of the device where electrochemical reactions occur and electrons flow. In one aspect, the invention provides a sensor, such as, for example, a biosensor, in the form of a strip, the sensor being suitable for electrochemical or optical measurement. The sensor comprises a base layer and a cover layer having a layer of mesh adhered thereto, and the base layer is separated from the cover layer by a spacer layer. The base layer, the cover layer having a layer of mesh adhered thereto, and the spacer layer define a flow channel into which a liquid sample is drawn therein and flows therethrough by means of wicking.Type: GrantFiled: February 23, 2004Date of Patent: August 8, 2006Assignee: Abbott LaboratoriesInventors: Mark E. Tess, Scott L. Bailey, Shridhara Alva Karinka

Patent number: 6939450Abstract: A device having a flow channel, wherein at least one flow-terminating interface is used to control the flow of liquid in the flow channel. The flow-terminating interface prevents the flow of the liquid beyond the interface. In one aspect, the invention provides a sensor, such as, for example, a biosensor, in the form of a strip, the sensor being suitable for electrochemical or optical measurement. The sensor comprises a base layer and a cover layer, and the base layer is separated from the cover layer by a spacer layer. The base layer, cover layer, and spacer layer define a flow channel into which a liquid sample is drawn therein and flows therethrough by means of capillary attraction. The flow of the sample is terminated by a flow-terminating interface positioned in the flow channel.Type: GrantFiled: October 8, 2002Date of Patent: September 6, 2005Assignee: Abbott LaboratoriesInventors: Shridhara Alva Karinka, Mark E.
