These patent-pending 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.
While the majority of contrast agents are engineered to alter the intensity of backscattered light, this class of near-infrared dyes was designed to transform spectral wavelength, making in situ and in vivo three-dimensional imaging a reality
Benefits:
Cell-specific targeting
Strong light penetration of tissue at NIR wavelengths

A spectral-domain magnetomotive optical coherence tomography apparatus, includes (a) a spectral-domain optical coherence tomography device, and (b) a magnet. The magnet is coupled with the optical coherence tomography device so that changes in the magnetic field are coordinated with collection of data by the optical coherence tomography device. This device may be used to examine a sample by spectral-domain magnetomotive optical coherence tomography, which includes examining the sample with a spectral-domain optical coherence tomography device, to collect optical coherence tomography data. The sample contains magnetic particles, and the magnetic particles are subjected to a changing magnetic field during the examining.

Embodiments of nanostructured, multilayered metal-dielectric particles suitable for use as Raman spectroscopic probes, as well as methods of designing, making and using such multilayered nanoparticles, and kits including the multilayered nanoparticles. The multilayered nanoparticles include alternating metal and dielectric layers and an outer dielectric shell. One or more of the dielectric layers may include a plurality of reporter molecules. Embodiments of the multilayered nanoparticles are suitable for detecting target analytes in a sample. Some embodiments of the multilayered nanoparticles are suitable for use in multiplexed assays, including assays for multiple target analytes having differing concentrations.

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.
Benefits:
Perform diagnostic and therapeutic functions
Capable of targeting specific cells and cell structures
Tunable optical properties
Variable resonance depending on particle orientation
