Special Issue Information

Dear Colleagues,

Polymer gels are an astonishing and fascinating material. At a first glance, they are just composed of a cross-linked polymer network and interstitial fluid. But their ability to absorb large amounts of water or other solvents and – associated with this – a huge volume change make them ideal candidates for technical applications. Apart from the swelling, two other properties make hydrogels especially attractive:

First, a strong volume change can be excited by a large spectrum of different physical and chemical factors. This regards for instance temperature, electrical voltage, pH, concentration of organic compounds in water, and salt and ion concentrations. Second, the volume change due to these physical or chemical stimuli is reversible. Hence, hydrogels are chemo-mechanical transducers converting chemical energy into mechanical energy and vice versa. This offers a huge potential for new sensor and actuator principles especially for applications in all fields where aqueous solutions play a decisive role, e.g. in process engineering, fluidics, chemistry, cell biology, and drug delivery. Such a behaviour makes hydrogels real “smart” materials.

Meanwhile, the first industrial applications of hydrogel-based sensor technology were reported. The next-generation sensors will not only be able to measure measurands other than traditional pH value or solvent concentration but will also provide new features like autarkic operation or the automatic adjustment of the measurement range. However, the utilization of these materials for chemical sensors still shows plenty of problems to be solved because sensors traditionally need properties like long-term stable characteristics, high reproducibility in the percent range and a selectivity towards the measurand without interference from other quantities.

To overcome these challenges new insights into the nature and the operation of hydrogels as part of technical systems are needed. Therefore we proposed this Special Issue to bring together new results in research and development that focus on the most recent advances in (i) phase-transition phenomena of stimuli-responsive hydrogels useful for sensor applications including their physical basis and modelling, (ii) basic transducer principles of hydrogel-based chemical sensors, (3) advanced systems employing hydrogel-based sensors, and (iv) novel or advanced approaches regarding the processing of hydrogels, the integration of hydrogels into technical environments and the fabrication of hydrogel-based sensors.

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.
