The use of multiplied beam splitting optics, as a core technology, permitted multi-point sensing to be achieved. This system was capable of simultaneously measuring nine sensing points. Calibration curves for sucrose obtained on nine sensing points were linear in the range of 0\u201310% with a correlation factor of 0.996\u20130.998 with a relative standard deviation of 0.090\u20134.0%. The detection limits defined as S\/N = 3 were 1.98 \u00d7 10\u22126\u20133.91 \u00d7 10\u22125 RIU. This sensitivity is comparable to that of conventional SPR sensors.<\/jats:p>","DOI":"10.3390\/s130100801","type":"journal-article","created":{"date-parts":[[2013,1,8]],"date-time":"2013-01-08T21:24:12Z","timestamp":1357680252000},"page":"801-812","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Development of a Novel Two Dimensional Surface Plasmon Resonance Sensor Using Multiplied Beam Splitting Optics"],"prefix":"10.3390","volume":"13","author":[{"given":"Akihide","family":"Hemmi","sequence":"first","affiliation":[{"name":"Mebius Advanced Technology Ltd., 3-31-6-107 Nishiogi-kita, Suginami-ku, Tokyo 167-0042, Japan"},{"name":"Department of Applied Chemistry, Graduate School of Engineering, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka 819-0395, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryosuke","family":"Mizumura","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry, Graduate School of Urban Environmental Sciences, Tokyo Metropolitan University, 1-1 Minamiohsawa, Hachioji, Tokyo 192-0397, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryuta","family":"Kawanishi","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry, Graduate School of Urban Environmental Sciences, Tokyo Metropolitan University, 1-1 Minamiohsawa, Hachioji, Tokyo 192-0397, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hizuru","family":"Nakajima","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry, Graduate School of Urban Environmental Sciences, Tokyo Metropolitan University, 1-1 Minamiohsawa, Hachioji, Tokyo 192-0397, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hulie","family":"Zeng","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry, Graduate School of Urban Environmental Sciences, Tokyo Metropolitan University, 1-1 Minamiohsawa, Hachioji, Tokyo 192-0397, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsumi","family":"Uchiyama","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry, Graduate School of Urban Environmental Sciences, Tokyo Metropolitan University, 1-1 Minamiohsawa, Hachioji, Tokyo 192-0397, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriaki","family":"Kaneki","sequence":"additional","affiliation":[{"name":"College of Design and Manufacturing Technology, Graduate School of Engineering, Muroran Institute of Technology, 27-1 Mizumotocho, Muroran 050-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihiko","family":"Imato","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry, Graduate School of Engineering, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka 819-0395, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"784","DOI":"10.1016\/j.snb.2004.11.094","article-title":"Surface plasmon resonance detection of endocrine disruptors using immunoprobes based on self-assembled monolayers","volume":"108","author":"Gobi","year":"2005","journal-title":"Sens.
