Detection of cardiac troponin or biological markers by a transverse wave surface acoustic wave biosensor using wet chemical bioanalytical techniques

摘要

The embodiment described isMethod of operating SAW sensor for detecting a sample in fluidIn the handheld portable assay and sensor system, including the following stepsProviding a sensing Lane functionalized to SAW sensors;Until the sample is fluidly disposed in the detection LaneThe process of maintaining a sensory detection Lane in a dry state of a SAW sensor;The process of fluidly placing a sample in a functionalized detection lane;Remove fluid from the functionalized detection LaneProcess to increase the probability of specific antibody antigen interactions by enriching samples in functionalized detection lanes;Cleaning the functionalized detection LaneLeaving substantially specific antigen antibody interactions in a functionalized detection lane;Removing fluid again from a functionalized detection lane;A method of measuring the concentration of a sample in a state free of fluid and in a functionalized detection lane.
