Abstract
A system for analyzing a content of a sample material is presented. The system includes a fiber sensitized to a first substance, and at least one electrode configured to expose the fiber to an electric field. The system includes an optical sensor configured to detect a displacement of the fiber when the fiber is exposed to the electric field, and a processor configured to use the displacement of the fiber to characterize a content of the sample material.
Claims12
A system for analyzing a sample comprising small target molecules in a solution, the system comprising:
- a mechanical support coupled to an optical fiber sensitized to the small target molecules in the solution;
- at least two electrodes positioned on opposing sides of the optical fiber and configured to expose the fiber to a modulated electric field modulated at a given frequency;
- a sensor operably positioned and that is configured to detect both an amplitude of oscillation of the optical fiber at the given frequency of the modulated electric field and a direction of its displacement;
- wherein said sensor is further configured to use said amplitude of oscillation of the optical fiber at the given frequency of the modulated electric field and the direction of its displacement to characterize the sample for a presence or absence of said small target molecules in the solution,
- wherein the modulated electric field minimizes electrochemical reactions and allows the use of noise reduction methods to remove noise and drift issues.
