Special Issue Information

Dear colleagues,

Chemical information is essential and necessary in environmental monitoring, industrial processing and medical diagnosis. This is the reason chemical sensing has attracted considerable attention in recent years. However, in most cases, chemical sensors are suffered from poor selectivity, low sensitivity and instablity in difficult and complex conditions. Advanced technologies and unique sensing strategies are required to improve the sensing performance of sensors. This special issue is dedicated to state-of-the-art research that is focused on chemical sensors appllied in complex and extreme conditions, including high temperatures, high humidity, within a living organism, and multiple environmental interferences. Papers describing novel sensing materials, sensing mechanisms, sensor package, sensing signal processing, practical sensor technology and applications are of interest.

Potential topics include but are not limited to the following:

  • Gas Sensors and Electronic Noses
  • Electrochemical Sensing
  • Nanosensors
  • Fiber Optic Chemical Sensors
  • Spectroscopic Chemical Sensing

Manuscript Submission Information

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 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 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 2700 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.

Gold amalgam microelectrodes (GAMEs) have been characterized and successfully calibrated to measure >1.5 mM (30 mg L−1) sulfide in artificial wastewater (AWW) using cathodic stripping voltammetry (CSV). Microbial sulfide generation in two types of AWW was traced. Artificial wastewater type 1 (AWW1) held the potential for almost 50% conversion of sulfur compounds at a maximum rate of ~4.3 ± 0.5 µM h−1 while AWW 2 held a potential for 75–100% conversion at a rate of 165 µM h−1. In addition, the GAMEs were thoroughly examined during fabrication, maturation, and aging. An earlier described plating method was found to result in varying electrode surfaces due to excess mercury deposition and, therefore, deviating stripping signals. The limited shelf life of GAMEs has been proposed previously. This study shows the extent of electrode surface changes during amalgam formation and the wear and tear of application. As a result, suggestions to optimize fabrication and application are discussed to provide reliable measurements and proceed toward a future commercialization. Full article
