Chemical and Biosensors: A Theme Issue in Honor of Professor Otto S. Wolfbeis

Dear Colleagues,

Otto S. Wolfbeis was a full professor of Analytical and Interface Chemistry at the University of Regensburg, Germany, from 1995 to 2012, and is well known as a pioneer in the field of luminescence chemo- and biosensors. He has authored numerous papers and reviews on optical (fiber) chemical sensors, fluorescent probes, labels, and bioassays; on advanced polymers for use in sensing schemes; on photonic crystals and upconversion particles; and on spectroscopic methods, including fluorescence (lifetime) and RGB-based digital imaging. Another field relates to bioimaging using advanced nanomaterials. Prof. Wolfbeis has also worked on various types of electrochemical sensors, typically on sensors for gases, neurological drugs and saliva biomarkers, in the aptamer-based electrochemical sensing of thrombin, and in enantioselective sensing. His group described the first capacitive immunosensor back in 1997, and several electrodes coated with molecularly imprinted polymers have been designed for use in impedimetric sensing. Finally, various kinds of analyte response materials were described for use in surface plasmon resonance sensing. His work is listed in https://scholar.google.com/citations?hl=en&user=pJlFf1IAAAAJ. Many of his sensors are now industrially manufactured. He has (co)edited several books and acted as the (co)organizer of several conferences related to fluorescence spectroscopy (MAF) . He is also the founder of the Europt(r)ode Conference Series, the most comprehensive international conference in the field of optical chemical sensors and biosensors. He was one of the 10 curators of Angewandte Chemie (VCH-Wiley, Weinheim), the editor-in-chief of Microchimica Acta (Springer-Nature, Vienna), and one of the three founding editors of Methods and Application in Fluorescence (Inst. Physics Publ., London).

This Special Issue is dedicated to celebrating the career of Professor Otto S. Wolfbeis in honor of his contributions in the field of chemical and biosensors. It will cover a selection of recent research and review articles on subjects ranging from new chemical sensors and biosensors, new probes and labels, novel quantifying methods, and their applications.

Chemical and biosensors are miniaturized analytical devices that can deliver real-time and online information on the presence of specific compounds, (bio)molecules, or ions in complex samples. They are playing increasingly important roles in both fundamental research and environmental and industrial sectors and have found enormous applications in biological research, health care, biomedical monitoring and imaging, environmental monitoring, and automation control. This Special Issue aims to provide an overview and show original innovations in current development and state-of-the-art techniques in chemical and biosensors in the journal Chemosensors. Potential topics include, but are not limited to:

• Reviews on chemical sensors and biosensors;
• Innovations on chemical sensors and biosensors;
• Optical sensors and biosensors;
• Electrochemical sensors and biosensors;
• Electrogenerated chemiluminescence sensors and biosensors;
• New sensor film or nanosensors;
• Novel sensor schemes and new quantifying methods;
• Applications of chemo- and biosensors;
• Advanced nanomaterials for use in sensing and bioimaging.

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. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind 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 monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
