Vanderbilt University researchers have designed a system for non-invasive discrimination between normal and cancerous skin lesions. The system combines the depth-resolving capabilities of OCT technique with Raman Spectroscopy's specificity of molecular chemistry. By linking both imagining techniques into a single detector arm, the complexity, cost, and size of previously reported RS-OCT instruments have been significantly improved. The combined instrument is capable of acquiring data sets that allow for more thorough assessment of a sample than existing optical techniques.

Vanderbilt researchers have created a novel technology for the diagnosis and monitoring of disease states using the rheological properties of a blood sample with a lateral flow membrane.

Vanderbilt University researchers have developed a technology that uses spatially offset Raman spectroscopy to obtain depth-resolved information from the margins of tumors. This helps to determine positive or negative tumor margins in applications such as breast lumpectomy, and the technology is currently being investigated for breast cancer margin detection.

Fluorescent labels having near-infrared (NIR) emission wavelengths have the ability to penetrate tissue deeper than other emission wavelengths, providing enormous potential for non-invasive imaging applications. However, advancement of optical imaging (particularly NIR imaging) is hindered by the limitation of narrow Stokes shift of most infrared dyes currently available in the market. Vanderbilt researchers have developed a novel NIR dye (4-Sulfonir) for multichannel imaging that enables in vivo imaging of multiple targets due to its large Stokes shift. 4-Sulfonir with its unique large Stokes shift (~150 nm) and wide excitation spectrum could be used in parallel with other NIR dyes for imaging two molecular events simultaneously in one target.
