<p>A calorimetric sensor and method of detecting a reaction based on the heat evolved. A cantilever spring element (3) having a first surface (5) having a first thermal expansion coefficient and a second surface (9) having a second thermal expansion coefficient is coated with a reagent (7). Sample (13) reacts the reagent (7) and the heat evolved changes the temperature of the spring (3), causing the first and second surfaces (5, 9) to expand differently, resulting in a measurable deflection of the spring (3). A reference spring (15) may be provided.</p> |
