“…The long interaction length between the evanescent tails of the guided light and the material attached to the surface of the optical fiber maximizes the fluorescence signal to give improved sensitivity of detection relative to more traditional spectroscopic and fluorescencebased fiber sensors. 20 Two different types of microstructured optical fibers were used in these experiments. The first is an exposed-core microstructured optical fibers (ECF) that has a suspended micron-scale core partially exposed to the external environment [21][22] ( Figure 2, left), which allows consistent washing, drying and refilling of the biosensor during its use.…”

“…These air holes confine light to the solid core and allow it to be guided along the length of the fiber. The holes also act as micro sample chamber to allow nanoscale sampling 20 , a real advance in biological sensing. sensing mechanism depicted here was modeled by Rivera-Fuentes et al 24 on a similar analog using density functional theory calculations.…”

The new agreement specifically addresses what authors can do with different versions of their manuscript -e.g. use in theses and collections, teaching and training, conference presentations, sharing with colleagues, and posting on websites and repositories. The terms under which these uses can occur are clearly identified to prevent misunderstandings that could jeopardize final publication of a manuscript (Section II, Permitted Uses by Authors). Easy Reference User Guide Posting Accepted and Published Works on Websites and Repositories:A digital file of the Accepted Work and/or the Published Work may be made publicly available on websites or repositories (e.g. the Author's personal website, preprint servers, university networks or primary employer's institutional websites, third party institutional or subject-based repositories, and conference websites that feature presentations by the Author(s) based on the Accepted and/or the Published Work) under the following conditions:• It is mandated by the Author(s)' funding agency, primary employer, or, in the case of Author(s) employed in academia, university administration.• If the mandated public availability of the Accepted Manuscript is sooner than 12 months after online publication of the Published Work, a waiver from the relevant institutional policy should be sought. If a waiver cannot be obtained, the Author(s) may sponsor the immediate availability of the final Published Work through participation in the ACS AuthorChoice program-for information about this program see http://pubs.acs.org/page/policy/authorchoice/index.html.• If the mandated public availability of the Accepted Manuscript is not sooner than 12 months after online publication of the Published Work, the Accepted Manuscript may be posted to the mandated website or repository. The following notice should be included at the time of posting, or the posting amended as appropriate: "This document is the Accepted Manuscript version of a Published Work that appeared in final form in [JournalTitle], copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see [insert ACS Articles on Request authordirected link to Published Work, see http://pubs.acs.org/page/policy/articlesonrequest/index.html]." • The posting must be for non-commercial purposes and not violate the ACS' "Ethical Guidelines to Publication of Chemical Research" (see http://pubs.acs.org/ethics).• Regardless of any mandated public availability date of a digital file of the final Published Work, Author(s) may make this file available only via the ACS AuthorChoice Program.

“…The power fraction of evanescent field increases with reducing core diameter, and a power fraction up to 30% in air can be achieved with a SCF with core diameter of 0.89 lm at k = 1550 nm. Investigations on the SCFs with similar structures have been carried out by Webb et al [35], Cordeiro et al [69] and Monro et al [67,70], respectively.…”

a b s t r a c tThis paper overviews recent development in gas detection with micro-and nano-engineered optical fibers, including hollow-core fibers, suspended-core fibers, tapered optical micro/nano fibers, and fiber-tip micro-cavities. Both direct absorption and photoacoustic spectroscopy based detection schemes are discussed. Emphasis is placed on post-processing stock optical fibers to achieve better system performance. Our recent demonstration of distributed methane detection with a $75-m long of hollow-core photonic bandgap fiber is also reported.

“…[1][2][3][4][5][6][7][8][9] MOFs can be fabricated from various glass types 25 including silica, tellurite, heavy metal fluoride, bismuth and lead silicate. Non-silica (soft) glasses can be readily fabricated using an extrusion process, which enables the formation of novel optical fibre architectures feasible for sensing applications.…”

May 2016Journal Name internal surface of the fibre structure. In characterising the fluoroionophore attachment, we observe that the fluorescence intensity from fluorescence imaging, the atomic nitrogen percentage measured by X-ray photoelectron spectroscopy (XPS), the carbonyl bond component (287.5 eV) in the XPS high resolution carbon spectrum, and Principal Component Analysis (PCA) of the time-of-flight secondary ion mass spectrometry (ToF-SIMS) data can be used to provide relative quantification of the concentration of an 15 attached fluoroionophore. We also show the first use of ToF-SIMS imaging and depth profiling of the Pb content within a glass substrate to provide information on the coverage provided by the coating and the relative thickness of an organic coating. Combined, these techniques provide a comprehensive picture of the coated glass surface that facilitates fibre sensor development.
