The resulting Hb\/FDU-15 film provided a favorable microenvironment for Hb to perform direct electron transfers at the electrode. The immobilized Hb also displayed its good electrocatalytic activity for the reduction of hydrogen peroxide. The results demonstrate that mesoporous carbon FDU-15 can improve the Hb loading with retention of its bioactivity and greatly promote the direct electron transfer, which can be attributed to its high specific surface area, uniform ordered porous structure, suitable pore size and biocompatibility. Our present study may provide an alternative way for the construction of nanostructure biofunctional surfaces and pave the way for its application to biosensors.<\/jats:p>","DOI":"10.3390\/s100201279","type":"journal-article","created":{"date-parts":[[2010,2,3]],"date-time":"2010-02-03T11:15:54Z","timestamp":1265195754000},"page":"1279-1290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Direct Electrochemistry and Electrocatalysis of Hemoglobin at Mesoporous Carbon Modified Electrode"],"prefix":"10.3390","volume":"10","author":[{"given":"Supeng","family":"Pei","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China"}]},{"given":"Song","family":"Qu","sequence":"additional","affiliation":[{"name":"College of Science, University of Shanghai for Science and Technology, Shanghai 200093, ChinaCollege of Science, University of Shanghai for Science and Technology, Shanghai 200093, China"}]},{"given":"Yongming","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China"}]}],"member":"1968","published-online":{"date-parts":[[2010,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7371","DOI":"10.1021\/ja981521d","article-title":"Direct electrochemistry of cofactor redox sites in a bacterial photosynthetic reaction center protein","volume":"120","author":"Kong","year":"1998","journal-title":"J.
