In this research, the basic imaging properties of the NIR-II imaging were first explored. To enable this, equipment for conducting NIR-II imaging were constructed and corresponding fluorescent materials were prepared. Liquid phantoms with Intralipid were used as a model system to verify the imaging ability, and the results obtained were verified with a CLARITY experiment. After obtaining such results, new methods to multiplex NIR-II fluorescence imaging and other biomedical procedures were proposed and explored. Taking the advantage of its special penetration ability, NIR-II imaging could be used to look into the transient process of the first several seconds of the distribution of fluorescent quantum dots administered via tail-vein injection. NIR-II imaging was also used to visualize the intestine structure and bowel movement real-time on nude mice. Furthermore, NIR-II imaging could be used in the tracking of stem cells inside a mouse brain. In the end, by multiplexing with radiotherapy, which generates Cerenkov photons, the NIR-II emitting quantum dots can be illuminated. This may provide a tool to help the precision delivery of dosage and real-time monitoring of the radiotherapy process. In this research, the potential of NIR-II imaging is explored, and the multiplexing ability of NIR-II imaging is demonstrated.\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Multiplexed Molecular Imaging in the Second Near-Infrared Window "}],"uid":"27707","created_gmt":"2018-09-05 19:14:39","changed_gmt":"2018-09-05 19:14:39","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2018-09-10T10:00:00-04:00","event_time_end":"2018-09-10T12:00:00-04:00","event_time_end_last":"2018-09-10T12:00:00-04:00","gmt_time_start":"2018-09-10 14:00:00","gmt_time_end":"2018-09-10 16:00:00","gmt_time_end_last":"2018-09-10 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
