This portfolio of optical contrast agents and molecular detection technologies were developed to enhance the ability of optical coherence tomography (OCT) to non-invasively map molecules in living specimens and diagnose disease where it starts. OCT utilizes low-coherence interferometry to measure the intensity of reflected or backscattered light to form images with micrometer resolution, is readily integrated with existing optical instrumentation and has application across a wide range of biological, medical, surgical, and non-biological specialties.
This class of nanospheres and nanorods exhibit tunable plasmon resonances and can be engineered to specific sizes with strong absorption or scattering at select wavelengths - most notably the near-infrared range - for enhancing the sensitivity and scope of OCT.
- Perform diagnostic and therapeutic functions
- Capable of targeting specific cells and cell structures
- Tunable optical properties
- Variable resonance depending on particle orientation
