Special Issue Information

Dear Colleagues,

The guided wave optics device for photonic sensors (including optical fiber sensors, planar waveguide sensors, and optical sensors) has been intensively studied over two decades for applications in biological and chemical measurements. Photonic sensors may be built based on different mechanisms such as intensity-based, phase-based, polarization-based, wavelength-based, Raman scattering-based, spectroscopic, surface plasmon resonance, and fluorescence emitted types. Progress in designing photonic sensors continues with new mechanism and guided wave optics device in different new fields. Thus, the special issue of journal of Chemosensors includes:

  • sensors based on optics/planar waveguide/ novel fibers including photonic crystal fiber, photonic bandgap fiber, and other specialty fiber like micro-nano fiber
  • novel demodulation techniques
  • applications in relatively new areas such as biomedical engineering and chemical engineering.

This special issue will give the reader some of the exciting areas of photonic sensors with this collection of innovative research articles. There will be no fees for all manuscripts in this special issue.

Submission

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Chemosensors is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Title: Three-Dimensional Photonic Crystal Based Sensing and Imaging of Potassium Ions
Authors: Christoph Fenzl, Michael Kirchinger, Thomas Hirsch, and Otto S. Wolfbeis
Affiliation: Institute of Analytical Chemistry, Chemo- and Biosensors, University of Regensburg, 93040 Regensburg, Germany
Abstract: We report on selective sensing of potassium ions in aqueous solution using an innovative sandwich assembly of photonic crystals and ion-selective mebrane. It is based on a new combination of an ionic strength sensitive photonic crystal hydrogel with a potassium ion-selective membrane consisting of the ion carrier valinomycin embedded into poly(vinyl chloride) (PVC). The reflected light of the film is of red color if immersed in water, becomes green in the presence of a 5 mM solution of potassium chloride and purple at concentrations of 100 mM. The signal change of this sensor is all but linear in the logarithmic concentration range from 1 × 10−3 to 5 × 10−2 mol·L–1. Further, we could show that other cations such as ammonium or sodium do not interfere. It was also possible to establish digital camera imaging for the potassium concentration in addition to reflection measurements. The digital images were taken at a fixed angle, separated into their red, green, and blue channels and analyzed separately resulting in calibration plots that were compared with those recorded by reflection measurements.
