We are developing hybrid nanoparticle (NP) systems for their potential use in combination therapy of cancer and image-guided therapy of atherothrombotic vascular diseases.\u003C\/p\u003E\u003Cp\u003EMitochondrial dysfunctions cause many human disorders. A platform technology of carrying bioactive molecules to the mitochondrial matrix could be of enormous potential benefit in therapeutics. We are developing a rationally designed, programmable NP platform for the diagnosis and targeted delivery of therapeutics for mitochondrial dysfunction related diseases. An optimized formulation for maximal mitochondrial uptake was identified through in vitro screening of a library of charge and size varied NPs and the uptake was studied by qualitative and quantitative investigations of cytosolic and mitochondrial fractions of cells treated with mitochondria-targeted blended NPs. The versatility of this platform was demonstrated by studying a variety of mitochondria-acting therapeutics for different applications. These include mitochondria targeting chemotherapeutics for cancer, mitochondrial antioxidant for Alzheimer\u2019s disease, and mitochondrial uncoupler for obesity. On the cardiovascular front, we are developing a long-circulating hybrid NP platform to selectively target macrophages and sense apoptosis for detection of plaque vulnerable to embolism.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EFor more information contact \u003Ca href=\u0022http:\/\/mailto:lyon@chemistry.gatech.edu\u0022\u003EProf. Andrew Lyon\u003C\/a\u003E (404-894-4090).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EProf.Shanta Dhar, University of Georgia\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E\u003Cem\u003ETargeted Nanocarriers for Delivery of Contrast Agents and Therapeutics\u003C\/em\u003E \u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EAnalytical Chemistry Seminar Series\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Shanta Dhar, University of Georgia"}],"uid":"27275","created_gmt":"2012-02-20 11:09:07","changed_gmt":"2016-10-08 01:58:05","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-09-11T17:00:00-04:00","event_time_end":"2012-09-11T18:00:00-04:00","event_time_end_last":"2012-09-11T18:00:00-04:00","gmt_time_start":"2012-09-11 21:00:00","gmt_time_end":"2012-09-11 22:00:00","gmt_time_end_last":"2012-09-11 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.chem.uga.edu\/people\/faculty\/dhar","title":"Prof. Shanta Dhar"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EShirley Tomes (404-894-0591) \u003Ca href=\u0022mailto:shirley.tomes@chemistry.gatech.edu\u0022\u003Eshirley.tomes@chemistry.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
