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.

Fluorescence Scanning System for Improvement of Analytical Ultracentrifugation

This technology includes improvements in the fluorescence scanner to increase efficiency. This method works by eliminating the need to radially slide the optical assembly during scanning, instead using a galvanometric mirror deflecting a laser beam to different positions in the sample. This allows the scanner to be incorporated into existing commercial analytical ultracentrifugation (AUC) systems with minimal modifications.

Improvement of Axial Resolution via Photoswitching and Standing Wave Illumination

This technology includes an illuminator and reflector that enables flexible standing wave illumination on an inverted microscope stand, and procedures for using such illumination to improve axial resolution in confocal or instant SIM imaging systems. The axial resolution in conventional fluorescence microscopy is typically limited by diffraction to ~700 nm. This method that improves axial resolution ~7-fold over the diffraction limit, and that can be applied to any fluorescence microscope.

Radiotherapy and Imaging Agent-based on Peptide Conjugated to Novel Evans Blue Derivatives with Long Half-life and High Accumulation in Target Tissue

This technology includes a newly designed, truncated Evans Blue (EB) form which allows labeling with metal isotopes for nuclear imaging and radiotherapy. Unlike previous designs, this new form of truncated EB confers site specific mono-labeling of desired molecules. The newly designed truncated EB form can be conjugated to various molecules including small molecules, peptides, proteins and aptamers to improve blood half-life and tumor uptake, and confer better imaging, therapy and radiotherapy.

Accelerating Multiview Registration and Iterative Deconvolution to Improve Spatial Resolution and Contrast in Fluorescence Microscopy

This technology includes algorithms and software that improve the speed of iterative deconvolution, a common method for improving spatial resolution and contrast in fluorescence microscopy images. These algorithms also improve the registration of multiview datasets, and apply deep learning to accelerate spatially varying deconvolution.

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.

PET Imaging of lntegrin Expression with Suitably Labeled RGD Peptides for Multiple Diagnostic Purposes

This technology includes a number of dimeric RGD peptides which been developed and labeled with various PET isotopes (1BF, 68Ga, and 64Cu) for imaging integrin expression in cancer, inflammation, rheumatoid arthritis, myocardial infarct, stroke and traumatic injury. A number of these peptides have been translated into clinic for diagnosis and therapy response monitoring.

Development of High-Throughput ELISA Based Binding Assays to Detect p53/p63/p73 Family Protein-DNA Interaction in the 96-well Microplate Format for Drug Screening and Other Clinical and Diagnostic Uses

This technology includes ELISA based binding assays of p53, p63 or p73 provide possibilities to validate genome sequencing results, and allow the performance of more in-depth investigation to address scientific mechanisms, as well as to develop applications for high-throughput clinical and diagnosis usages. While quantitative p53 binding assays have been commercially developed, there is a lack of high-throughput method to detect binding activity of all three p53/p63/p73 family members, which are an important step for these transcription factors to perform their function.

Paper Strip Tool with Gold Nanoparticle Conjugated Probes for Rapid Detection of Pathogens in Stool

This technology includes a paper strip tool that may be used at the point-of care to detect the presence of a multiplex of pathogen nucleic acid sequences in stool without the need for molecular amplification, laboratory or instrumentation. This invention can be used to rapidly and inexpensively detect gastrointestinal and diarrheal disease in order to guide treatment.

Apparatus for Cryogenic-Electron Microscopy Sample Preparation

Cryo-Electron Microscopy (cryo-EM) is used to obtain high-resolution structural images of macromolecular structures. Samples must be purified and loaded onto cryo-EM grids before imaging. The ideal cryo-EM grid consists of particles that are evenly and richly distributed in a broad distribution of orientations throughout the holes of the support film. Current techniques to prepare cryo-EM grids are performed manually and require trial and error, resulting in a bottleneck in cryo-EM workflows.
