The structure-directing agent we use is cetyltrimethylammonium bromide (CTAB) which forms a bilayer on the gold nanorod surface.  In Short Story #1, \u0022Outside and Inside,\u0022 I will describe experiments in which we coat the outside of the CTAB bilayer to introduce chemical functionality to the nanorods on the outside, and also use the CTAB bilayer to take up hydrophobic molecules from aqueous solution to the inside of the bilayer, which has interesting environmental implications.  In Short Story #2, \u0022Cells and Gels,\u0022 I describe experiments in which we incubate living cells, either in supported on a film or in a collagen gel, with nanorods in order to determine effects on the cells (toxicity, changes in gene expression, etc.).  In Short Story #3, \u0022The Estuary,\u0022 I describe experiments in which we introduce gold nanorods into model coastal ecosystems and measure (by ICP-MS) how the gold is distributed in water, sediment, plants and animals.\n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:christine.payne@chemistry.gatech.edu\u0022\u003EDr. Christine Payne\u003C\/a\u003E (404-385-3125).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Prof. Cathy Murphy, University of South Carolina\n\nThree Short Stories About Gold Nanorods\n\nJoint Physical\/Inorganic Seminar Series","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Cathy Murphy, University of South Carolina"}],"uid":"27275","created_gmt":"2008-01-28 01:00:00","changed_gmt":"2016-10-08 01:57:24","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-09-23T16:00:00-04:00","event_time_end":"2008-09-23T17:00:00-04:00","event_time_end_last":"2008-09-23T17:00:00-04:00","gmt_time_start":"2008-09-23 20:00:00","gmt_time_end":"2008-09-23 21:00:00","gmt_time_end_last":"2008-09-23 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.chem.sc.edu\/people\/facultyStaffDetails.asp?SID=32","title":"Prof. Cathy Murphy, University of South Carolina"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"89","name":"chemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
