Intralipid as a Contrast Agent to Enhance Subsurface Blood Flow Imaging

This technology includes a blood flow imaging method that allows for a higher density of smaller particles to be detected. Current imaging methods that are based on Doppler measurements are limited by the discontinuity in the capillary flow in the space between red blood cells. The core technology is to use a scattering agent to enhance capillary flow or microcirculation. This technology has been tested for optical coherence Doppler tomography, but can be expended to any Doppler based flow imaging techniques such as laser speckle imaging.

Three-dimensional Fluorescence Polarization Excitation via Multiview Imaging

This technology includes a method that extends fluorescence polarization imaging so that the dipole moment of a fluorescent dye may be excited regardless of its 3D orientation. By exciting the dipole from multiple directions, we ensure that excitation may occur even if the dipole is unfavorably oriented along the axial (propagation) axis. If the dye can be rigidly attached to the structure of interest, our method also enables the 3D orientation of the structure to be estimated accurately.

Producing Isotropic Super-Resolution Images from Line Scanning Confocal Microscopy

This technology includes a microscopy technique that produces super-resolution images from diffraction-limited images obtained from a line scanning confocal microscope. First, the operation of the confocal microscope is modified so that images with sparse line excitation are recorded. Second, these images are processed to increase resolution in one dimension. Third, by taking a series of such super-resolved images from a given sample type, a neural network may be trained to produce images with 1D super-resolution from new diffraction-limited images.

Multichannel Individualized Seizure Therapy (MIST) Device

The Multichannel Individualized Stimulation Therapy (MIST) device is a multichannel electrical stimulation system that can be used for targeted, individualized electroconvulsive therapy (ECT), especially for treatment-resistant depression (TRD). Millions of individuals suffer from TRD, for which ECT is often the most efficacious and rapidly acting treatment option.

Single Source-Detector Separation Approach to Calculate Tissue Oxygen Saturation

Summary: 
The National Institute of Child Health and Human Development (NICHD) seeks partners and/or licensees to further develop and commercialize the miniaturized tissue oximeter for implementing the single source-detector separation algorithm in existing devices/systems to collect tissue oxygen saturation.

Non-Contact Total Emission Detection Methods for Multiphoton Microscopy: Improved Image Fidelity and Biological Sample Analysis

The technology offered for licensing and for further development is in the field of multiphoton microscopy (MPM). More specifically, the invention pertains to optical designs that can enhance and extend the capabilities of MPM in spectral imaging of biological samples. The unique design of the light collection and the detection optics maximizes the collection of emitted light, thus increasing the signal and hence the signal-to-noise ratio (SNR).

Device for Selective Partitioning of Frozen Cellular Products

Cryopreservation using liquid nitrogen frozen polyvinyl bags allows for storing cellular materials for extended periods while maintaining their activity and viability. Such bags are commonly used in the clinic to store blood products including blood cells, plasma, hematopoietic stem cells, umbilical cord blood for future uses including transplantation. These materials, typically obtained in limited quantities, may be of great therapeutic value, as is the case of stem cells or cord blood derived cells which can be used to potentially treat a number of diseases.

Capillary Viscometer for Measuring Viscosity of Macromolecular Solutions of Biological Relevance

A capillary-based device and system for measuring the rheological properties of solutions of synthetic and biological polymers. The device automatically serially dilutes and varies the flow rate of a sample, permitting measurement of solution viscosity across wide ranges of concentration and shear rate without changing samples. The device can rapidly and accurately assay solute stability, solute-solvent and solute-solute interactions in solutions of proteins and other macromolecules of biotechnological and pharmaceutical interest, as well as solution injectability.

CDC Mosquito Trap for Control and Surveillance of Mosquitoes Including Carriers of Zika & Other Viruses

Mosquitoes are responsible for spreading many viruses that can make people sick, including dengue, Zika, chikungunya, yellow fever, and more. The Centers for Disease Control and Prevention's (CDC's) new autocidal gravid ovitrap (AGO) mosquito trap is an inexpensive, simple-to-assemble, and easy-to-maintain trap that targets female mosquitoes looking for a place to lay eggs. The current trap model stands 18 inches (45cm) tall and is made of a 5-gallon (18L) bucket. The AGO trap's unique design lures mosquitoes by using water and an all-natural, organic hay attractant.
