Abstract: Presented herein is a multichannel imaging system capable of detecting and distinguishing multiple fluorescent light sources simultaneously. Also described herein are methods of using the system to image disease or cellular abnormalities, e.g., for diagnostic and/or intraoperative purposes.

Abstract: Described herein are systems and methods for intracellular imaging, assessment, and/or treatment of tissue before, during, and/or after surgical procedures using nanoparticles (e.g., less than 50 nanometers in diameter, e.g., photoswitchable nanoparticles) and/or a super-resolution microscope system. The present disclosure describes nanoparticles (e.g., nanosensors and photoswitchable nanoparticles) that are used to monitor and/or track changes in environmental conditions and/or analytes in the cellular microenvironment before, during, and/or after surgical procedures. The present disclosure also describes systems and methods that provide information related to the distribution and/or delivery of photoswitchable nanoparticles at super resolution (e.g., using super-resolution microscopy).

Abstract: Described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C? dots) to graphically differentiate specific nerves (e.g., sensory nerves vs. motor nerves) for nerve transplants and other surgeries. Also described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C? dots) to graphically differentiate between different types of lymph nodes and/or lymphatic pathways, e.g., to safely and effectively perform vascularized lymph node transplantation in the treatment of lymphedema. Also described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C? dots) to graphically differentiate parathyroid tissue.
