Special Issue Information

Dear Colleagues,

In recent years, various polymers have been extensively used to develop biosensors. The applicability of these materials increased with the combination of two or three other materials. In this context, the development of hybrid material-based biosensors to be used as medical diagnostic tools, as well as in food analysis or environmental monitoring has garnered traction.

Given this context, we are pleased to announce the launch of this Special Issue, entitled ‘Biosensing Based on Nanohybrid Materials’, which aims to collate research concerning the design, characterization, and fabrication of biosensors based on nanohybrid materials, with potential applications in the detection of metabolites of clinical interest, pharmaceuticals, food analysis, and environmental monitoring. We welcome submissions of original research articles, communications, and reviews.

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. Biosensors 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.

Glucosamine–chitosan synthesized by the Maillard reaction was combined with montmorillonite to obtain a nanohybrid composite to immobilize horseradish peroxidase. The material combines the advantageous properties of clay with those of the chitosan derivative; has improved water solubility and reduced molecular weight and viscosity; involves an eco-friendly synthesis; and exhibits ion exchange capacity, good adhesiveness, and a large specific surface area for enzyme adsorption. The physicochemical characteristics of the composite were analyzed by infrared spectroscopy and X-ray diffraction to determine clay–polycation interactions. The electrochemical response of the different polyphenols to glassy carbon electrodes modified with the composite was evaluated by cyclic voltammetry. The sensitivity and detection limit values obtained with the biosensor toward hydroquinone, chlorogenic acid, catechol, and resorcinol are (1.6 ± 0.2) × 102 µA mM−1 and (74 ± 8) nM; (1.2 ± 0.1) × 102 µA mM−1 and (26 ± 3) nM; (16 ± 2) µA mM−1 and (0.74 ± 0.09) μM; and (3.7± 0.3) µA mM−1 and (3.3 ± 0.2) μM, respectively. The biosensor was applied to quantify polyphenols in pennyroyal and lemon verbena extracts. Full article
