专利号:US-2023096053-A1 优先权日:2019-12-06 标 题:Genetically-targeted chemical assembly: building functional structures and materials in living cells, tissues, and animals 发明人:DEISSEROTH KARL A; BAO ZHENAN; LIU JIA; RAMAKRISHNAN CHARU; KIM YOON SEOK; TOM ARIANE C 权利人:UNIV LELAND STANFORD JUNIOR 摘要:Compositions and methods are provided for genetically modifying cells to guide in situ chemical synthesis of electroactive, conductive, or insulating polymers on plasma membranes, organelle membranes, or subcellular surfaces of cells. In particular, compositions and methods are provided for genetically modifying excitable cells such as neurons, muscle cells, and endocrine cells to guide in situ chemical synthesis of polymers on the extracellular side of the plasma membrane. The subject methods can be used in various applications, for example, to assemble polymers in vivo at targeted locations to modulate electrical conduction and create new electrical conduction pathways, allow cell-type-specific neuromodulation, provide a conductive structure on cells for connection to electrodes, sensors, or other external electronic and electrochemical devices, and create a durable structure to replace damaged tissue for use in regenerative medicine.
专利号:US-11617804-B2 优先权日:2014-07-18 标题:Hyaluronic acid-based nanoparticles as biosensors for imaging-guided surgery and drug delivery vehicles and methods associated therewith 发明人:MOHS AARON MICHAEL; HILL TANNER KINKADE; KELKAR SNEHA SANJAY; KRIDEL STEVE 权利人:UNIV WAKE FOREST 摘要: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 2 is possible with optical imaging, significantly higher than other imaging modalities. n 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.
