Systems, Methods and Computer Readable Storage Media for Analyzing a Sample

A sensor unit configured to be used with a sensing device that is configured to analyze a sample, the module comprising:

• a chip including at least one sensor target to be tested;
• at least one fluid connector configured for fluid communication with a sensing device;
• and
• a connector configured to connect the module to a sensing device.

A system configured to analyze a biological sample, comprising:

• (a) a sensor unit comprising one or more piezoelectric sensors having fixed biomolecules with binding sites for at least one target biomarker;
• (b) a sensing device in communication with the sensor unit, the sensing device configured to obtain sensor data from the sensor unit, the sensor data corresponding to a resonant frequency of the one or more piezoelectric sensors over time;
• and
• (c) an analysis device in communication with the sensing device and including one or more processors configured to perform analysis of the data to determine at least one of a presence or concentration of at least one target biomarker in the biological sample, wherein the analysis comprises the steps of:
• receiving the sensor data from the sensing device;
• extracting one or more data features corresponding to one or more resonance frequency shifts over a period of time, the resonance frequency shifts representative of piezoelectric changes caused by binding of the at least one target biomarker within the biological sample to the fixed biomolecules;
• outputting, based on the one or more data features, classification information about the biological sample, the classification information comprising results representative of at least one of the presence or concentration of the at least one target biomarker.
