A conformal graphene-decorated nanofluidic sensor is employed to mimic the functions of a prism, sensing plate, and fluidic channel in the tradition setup. Simulation results show that the redshift of the resonant wavelength results in the improvement of sensitivity up to 4525 nm\/RIU. To reshape the broadened spectral lines induced by the redshift of the resonant wavelength to be narrower and deeper, a reflection-type configuration is further introduced. By tuning the distance between the graphene and reflective layers, the figure of merit (FOM) of the device can be significantly improved and reaches a maximum value of 37.69 RIU\u22121, which is 2.6 times that of the former transmission-type configuration. Furthermore, the optimized sensor exhibits superior angle-insensitive property. Such a conformal graphene-decorated nanofluidic sensor offers a novel approach for graphene-based on-chip fluidic biosensing.<\/jats:p>","DOI":"10.3390\/s16060899","type":"journal-article","created":{"date-parts":[[2016,6,16]],"date-time":"2016-06-16T10:23:20Z","timestamp":1466072600000},"page":"899","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Conformal Graphene-Decorated Nanofluidic Sensors Based on Surface Plasmons at Infrared Frequencies"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9850-6661","authenticated-orcid":false,"given":"Wei","family":"Wei","sequence":"first","affiliation":[{"name":"Key Laboratory of Optoelectronic Technology &amp; Systems, Ministry of Education of China, Chongqing University, Chongqing 400044, China"},{"name":"College of Optoelectronic Engineering, Chongqing University, Chongqing 400044, China"},{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 401122, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinpeng","family":"Nong","sequence":"additional","affiliation":[{"name":"Key Laboratory of Optoelectronic Technology &amp; Systems, Ministry of Education of China, Chongqing University, Chongqing 400044, China"},{"name":"College of Optoelectronic Engineering, Chongqing University, Chongqing 400044, China"},{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 401122, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linlong","family":"Tang","sequence":"additional","affiliation":[{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 401122, China"},{"name":"Chongqing Engineering Research Center of Graphene Film Manufacturing, Chongqing 401329, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guiwen","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Optoelectronic Engineering, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Yang","sequence":"additional","affiliation":[{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 401122, China"},{"name":"Chongqing Engineering Research Center of Graphene Film Manufacturing, Chongqing 401329, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Luo","sequence":"additional","affiliation":[{"name":"College of Optoelectronic Engineering, Chongqing University, Chongqing 400044, China"},{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 401122, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2636","DOI":"10.1021\/nl500574n","article-title":"LSPR chip for parallel, rapid, and sensitive detection of cancer markers in serum","volume":"14","author":"Acimovic","year":"2014","journal-title":"Nano Lett."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1080\/09500340.2015.1066455","article-title":"Study of a symmetrically structured SPR sensor and its dual-wavelength differential method","volume":"63","author":"Yang","year":"2015","journal-title":"J.
