In particular, we work on the preparation and study of nanoporous colloidal films and membranes that form via self-assembly of nanoscale-sized silica spheres into a close-packed face-centered cubic lattice and contain highly ordered arrays of three-dimensional interconnected pores 5-100 nm in size.  We modify the surface of colloidal nanopores with organic moieties that can non-covalently interact with ions and molecules, and whose charge and shape respond to external stimuli, such as pH or light.  As a result of the surface modification, we are able to control the molecular transport through the colloidal nanopores, either by tuning the nature and strength of the non-covalent interactions or by changing the environmental conditions.  Our research addresses fundamental problems of controlling the molecular transport through nanoscale-sized artificial pores.  We believe that integrating nanoscale, functional organic moieties into the surface of colloidal materials will allow creating responsive nanoscale devices with a host of technological applications in drug delivery, separations, sensing and fuel cells.\n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:lyon@chemistry.gatech.edu\u0022\u003EDr. Andrew Lyon\u003C\/a\u003E (404-894-4090).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Prof. Ilya Zharov, University of Utah\n\nResponsive Nanoporous Organic-Inorganic Colloidal Materials","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Ilya Zharov, University of Utah"}],"uid":"27275","created_gmt":"2007-09-06 00:00:00","changed_gmt":"2016-10-08 01:57:24","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-02-14T14:00:00-05:00","event_time_end":"2008-02-14T15:00:00-05:00","event_time_end_last":"2008-02-14T15:00:00-05:00","gmt_time_start":"2008-02-14 19:00:00","gmt_time_end":"2008-02-14 20:00:00","gmt_time_end_last":"2008-02-14 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.chem.utah.edu\/directory\/faculty\/zharov.html","title":"Prof. Ilya Zharov, University of Utah"}],"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":""}}}
