Special Issue Information
Dear Colleagues,
Recent developments in colorimetric sensors, which have been an important trend in the past two decades, have helped researchers to make rapid progress in analytical chemistry, with several eminent research groups worldwide working to prepare novel chemical sensing platforms. These systems can be cost-effective, sensitive, and selective, and can also be printed on chips or surfaces. Moreover, the main advantages of such methods include the possibility of designing naked eye visualization systems or ease of measuring changes in color using microtiter plate readers, smartphones, cameras, or using image capturing systems. Several approaches have advanced the rapidly evolving field of sensing for the detection of clinical markers, emerging diseases, pesticides, antibiotics, micro-pollutants, heavy metals, and toxic chemical compounds in an inexpensive way, including visual imaging and spectrophotometric or fluorometric measurements. Generally, the three most popular approaches, which have been predominantly used in developing colorimetric sensors, include (i) linking a chromophore group to a receptor unit through covalent bonding, (ii) the use of competitive assays between a certain analyte and a dye attached to a receptor, and (iii) the use of unique molecular systems that follow guest-induced chemical reactions to produce appropriate colorimetric changes. However, the application of nanomaterials in colorimetric and fluorometric sensing systems has the potential to offer a full set of novel properties and advances to be explored. This Special Issue is proposed to offer a timely contribution to issues of great concern in recently emerging concepts, materials, and technologies in areas including sensing, detection, diagnosis, and monitoring.
Research topics include but are not limited to the scope of the Special Issue, which covers sensors that involve nanomaterials in the recognition moiety (supramolecular hybrid materials), in the signaling groups (metal nanoparticles, fluorescent nanoparticles, quantum dots), or sensing devices, chips, and paper-based sensors (aggregation processes). Furthermore, other areas such as chromogenic arrays, fluorescent dyes, or other emerging fields in sensing can be discussed. Research papers, short communications, and review articles are most welcome. For authors intending to submit a review article, it would be useful to send the first title page, abstract, and summary of content and graphical representations to the Guest Editor prior to submission. Researchers and scientists are warmly invited to submit well-written and edited manuscripts for publication.

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.
