Improved Tumor Margins Detection Using Gold Nano-rods

The Problem

Most optical-physiological diagnoses are based on the insertion of light, with known parameters, to a tested tissue, followed by the measurement of the reflected, transmitted, or absorbed light. Changes in the optical properties of this light such as its spectrum, polarization, or intensity, compared to the injected light, result from interactions of the irradiated light with the tissue's components. Current methods are not only as sensitive as required but also are invasive causing pain to patients.

The Solution

Our cutting-edge method for cancer detection is based on Diffusion Reflectance (DR) measurements of gold nanorods (GNR).

The Commercial Benefit

Like no other current solution, it is a noninvasive detection method for oral cancer (including mouth, tongue, ear, nose, throat, and vocal chords cancers). Compared to competing solutions, our novel innovation has high sensitivity (90%), selectivity, and specificity (97%).

We present simple and fast tumor detection with no intrusive surgery and up to 6 mm deep in the tissue.

Market Potential
