Abstract

A device and method detect a feature of a fluid or a target element in the fluid by contacting the fluid to a sensing surface on a substrate. A mechanical wave comprising shear-vertical wave components is propagated through the substrate to mix the fluid, conduct desorption of at least one non-target element from the sensing surface, and/or impede adsorption of the non-target element to the sensing surface. The feature of the fluid or the target element in the fluid is then detected on the sensing surface, wherein the detection is accelerated by the above-mentioned mixing of the fluid, desorption of at least one non-target element from the sensing surface, and/or impeding of the adsorption of the non-target element to the sensing surface.
