Patent number: 9863942Abstract: Disclosed herein are methods and devices for detecting the presence of an analyte of interest. A biosensor device can include a reaction chamber and an electrochemical detection chamber. The reaction chamber can include at least one immobilized binding site and a probe conjugate adapted to bind to at least one of the target analyte and the immobilized binding site while the detection chamber can include electrodes for detecting an electrochemical reaction. If present, the target analyte in the fluid sample results in a change in the amount of probe conjugate bound in the reaction chamber, which can be detected electrochemically in the detection chamber.Type: GrantFiled: September 18, 2009Date of Patent: January 9, 2018Assignee: Universal Biosensors Pty LtdInventors: Alastair McIndoe Hodges, Ronald Chatelier, Dennis Rylatt

Patent number: 8182765Abstract: A microfluidic device for transferring liquid from a first chamber to a second chamber is provided. The device has a first chamber; a second chamber; and a barrier between the first chamber and the second chamber, the barrier having least one opening fluidly connecting the first chamber to the second chamber, the at least one opening being sized such that a retention force, such as surface tension, keeps the liquid in the first chamber. The fluid is transferred from the first chamber to the second chamber when an initiation input such as fluid pressure is introduced to the liquid that is sufficient to overcome the retention force. The device may be a sensor strip.Type: GrantFiled: February 15, 2007Date of Patent: May 22, 2012Assignee: Universal Biosensors Pty LtdInventors: Alastair Mcindoe Hodges, Ronald Christopher Chatelier, Garry Chambers
