Special Issue Information

Dear Colleagues,

As an analogue of graphene and other closely related inorganic two-dimensional (2D) materials such as transition-metal dichalcogenides, 2D organic materials including 2D covalent organic frameworks, 2D metal-organic frameworks, 2D polymers and supramolcular polymers etc have attracted great attention of researchers. Their periodic porous structure, ultrahigh surface areas, well designable topology and electronic structures endow them great potential in applications in sensing devices. This special issue aims to summarize the recent progress in synthesis and biosensing application of 2D organic materials, including the design and synthesis of 2D organic materials toward the application of sensing device, such as the functionalization of 2D organic materials, strategies toward the synthesis of high-quality thin films, application of these materials in sensing devices toward biorelevant targets from ions and biomolecules to proteins, viruses, and even bacteria and cells etc.

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.

Optical sensors, especially fluorescence sensors, have been widely used because of their advantages in sensing, such as the high sensitivity, good selectivity, no radiation source, and easy operation. Here, we report an example of fluorescence sensing based on two-dimensional (2D) covalent organic polymers and highlight that the material can achieve a fast response and multi-signal output. This 2DPTPAK+TAPB-based sensor can quickly detect aromatic hydrocarbons and Fe3+ by the fluorescence signal or electrical resistance signal. Full article
