The present invention relates to intraoperative fluorescent imaging (IFI) used both pre-clinically using in-vivo models, as well as clinically to map sentinel lymph nodes in breast cancer, skin cancer, GI cancer, lung cancer, prostate cancer and several other cancers. IFI can be used to image solid tumors both non-specifically in hepatobiliary and breast cancers as well as in prostate and ovarian cancer. In one embodiment, two-dimensional resolution to 10 μm.sup.2 is possible with optical imaging, significantly higher than other imaging modalities. In one embodiment, the present invention relates to a series of self-assembled nanoparticles using HLA (hyaluronic acid) as both a polymeric backbone as well as targeting ligand. In some embodiments, the present invention relates to the synthesis of HLA conjugates, and the effect of variation of the hydrophobic ligand structure and conjugation level on nanoparticle self-assembly, size, ICG loading efficiency, and ICG fluorescence quenching and reactivation.

A method of imaging tissue of a subject using an electronic rolling shutter imager includes sequentially resetting rows of pixels of the rolling shutter imager from a first row to a last row, sequentially reading charge accumulated at the rows of pixels from the first row to the last row, wherein the first row is read after resetting the last row, illuminating the tissue of the subject with illumination light for an illumination period that lasts longer than a vertical blanking period, wherein the vertical blanking period is the period from the resetting of the last row to the reading of the first row, and generating an image frame from the readings of charge accumulated at the rows of pixels, wherein at least one reading of charge accumulated at a row of pixels is removed or replaced to generate the image frame.

The present disclosure relates to prostate specific membrane antigen (PSMA) targeted compounds conjugated to near-infra red (NIR) dyes and methods for their therapeutic and diagnostic use. More specifically, this disclosure provides compounds and methods for diagnosing and treating diseases associated with cells and/or vasculature expressing prostate specific membrane antigen (PSMA), such as prostate cancer and related diseases. The disclosure further describes methods and compositions for making and using the compounds, methods incorporating the compounds, and kits incorporating the compounds.

There is provided a novel conjugate that binds to the cell surface receptor uPA (uPAR). The conjugate is based on a fluorescence-labeled peptide useful as a diagnostic probe to the surfaces of cells expressing uPAR. The conjugate is capable of carrying a suitable detectable and imageable label that will allow qualitative detection and also quantitation of uPAR levels in vitro and in vivo. This renders the surgical resection of tumors more optimal.
