Abstract
A cartridge for sample handling and sensing includes (i) a sample port; (ii) a first fluid port connected to the sample reservoir in the distal region via a first fluid channel; and (iii) a second fluid port connected to the sample reservoir via a second fluid channel. The cartridge includes (i) a sensor platform comprising a bulk acoustic wave (BAW) resonator and a fluid flow path comprising a sensing region extending across a sensing surface of the BAW resonator; and (ii) a fluid valve between the sample reservoir and the sensing region. A sample may be applied to the sample port; first volume of fluid may be injected through the first fluid port; and then a second volume of fluid may be injected through the second fluid port to drive the sample into the sensing region of the fluid flow path.
