Abstract
An example method for detecting an analyte in a sample of a bodily fluid comprises the steps of exposing the bodily fluid sample to electromagnetic energy to cause a thermoelastic expansion in the analyte, and detecting a photoacoustic signal in the sample that results from the thermoelastic expansion.
Claims7
A system for detecting one or more analytes in a bodily fluid comprising:
- a test chamber having at least one sidewall and configured to contain at least a portion of a bodily fluid sample;
- an electromagnetic energy source configured to direct an energy source into said test chamber through said at least one sidewall and to induce a thermoelastic expansion in said one or more analytes;
- and,
- a sensor configured to detect said thermoelastic expansion in said bodily fluid sample in said test chamber.
