High selectivity is achieved by functionalizing the surface of an only-core poly(methyl methacrylate) (PMMA) polymer optical fiber with phenilboronic groups, and enhanced sensitivity by using a U-shaped geometry. Employing a supercontinuum light source and a high-resolution spectrometer, absorption measurements are performed in the broadband visible light spectrum. Experimental results suggest the feasibility of such a fiber probe as a low-cost and selective glucose detector.<\/jats:p>","DOI":"10.3390\/s18010034","type":"journal-article","created":{"date-parts":[[2017,12,26]],"date-time":"2017-12-26T03:06:38Z","timestamp":1514257598000},"page":"34","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["U-Shaped and Surface Functionalized Polymer Optical Fiber Probe for Glucose Detection"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7222-0043","authenticated-orcid":false,"given":"Mikel","family":"Azkune","sequence":"first","affiliation":[{"name":"Department of Communications Engineering, University of the Basque Country (UPV\/EHU), Engineering School of Bilbao, Plaza Ingeniero Torres Quevedo, 1, E-48013 Bilbao, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2045-008X","authenticated-orcid":false,"given":"Leire","family":"Ruiz-Rubio","sequence":"additional","affiliation":[{"name":"Macromolecular Chemistry Research Group (LABQUIMAC), Department of Physical Chemistry, Faculty of Science and Technology, University of the Basque Country (UPV\/EHU), Barrio Sarriena s\/n, E-48940 Leioa, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gotzon","family":"Aldabaldetreku","sequence":"additional","affiliation":[{"name":"Department of Communications Engineering, University of the Basque Country (UPV\/EHU), Engineering School of Bilbao, Plaza Ingeniero Torres Quevedo, 1, E-48013 Bilbao, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7409-6760","authenticated-orcid":false,"given":"Eneko","family":"Arrospide","sequence":"additional","affiliation":[{"name":"Department of Applied Mathematics, University of the Basque Country (UPV\/EHU), Torres Quevedo 1, E-48013 Bilbao, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leyre","family":"P\u00e9rez-\u00c1lvarez","sequence":"additional","affiliation":[{"name":"Macromolecular Chemistry Research Group (LABQUIMAC), Department of Physical Chemistry, Faculty of Science and Technology, University of the Basque Country (UPV\/EHU), Barrio Sarriena s\/n, E-48940 Leioa, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2045-008X","authenticated-orcid":false,"given":"I\u00f1aki","family":"Bikandi","sequence":"additional","affiliation":[{"name":"Department of Communications Engineering, University of the Basque Country (UPV\/EHU), Engineering School of Bilbao, Plaza Ingeniero Torres Quevedo, 1, E-48013 Bilbao, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseba","family":"Zubia","sequence":"additional","affiliation":[{"name":"Department of Communications Engineering, University of the Basque Country (UPV\/EHU), Engineering School of Bilbao, Plaza Ingeniero Torres Quevedo, 1, E-48013 Bilbao, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0188-4579","authenticated-orcid":false,"given":"Jose","family":"Vilas-Vilela","sequence":"additional","affiliation":[{"name":"Macromolecular Chemistry Research Group (LABQUIMAC), Department of Physical Chemistry, Faculty of Science and Technology, University of the Basque Country (UPV\/EHU), Barrio Sarriena s\/n, E-48940 Leioa, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,12,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/j.jobcr.2015.12.002","article-title":"Biosensors and Their Applications\u2014A Review","volume":"6","author":"Mehrotra","year":"2016","journal-title":"J.
