Special Issue Information

Dear Colleagues,

The immune sensor community has been experiencing rapid growth in the last decades. The immune sensor has the ability to identify target antigens quickly and generate immunocomplexes without the need to add supplementary reagents. Due to its excellent detection performance in terms of specificity and sensitivity, it has become a popular analytical instrument. Especially in recent years, digital and miniaturization of immunosensors are widely applied for the detection of various pathogens. Among the commonly used immunosensors, the optical immunosensor features prominently as an effective tool for the quantification of the number of antibodies, antigens, or haptens in complex samples with high sensitivity and specificity. This Special Issue will focus on the latest advances in optical immune sensors for proof of art demonstration or clinical analysis. Both review articles and novel research papers are solicited, covering the following areas:

(1) Novel optical sensors or platforms that could observe an immune response, direct or indirect, i.e., through observation of binding events or from fluorescence detection.

(2) Optical sensors that could improve the sensitivity, accuracy and precision of biomedical analysis and diagnostics.

(3) Optimisation of fabrication process, data processing strategies, and consistency to improve the performance of optical immunosensors.

(4) The combination of optical sensors with different technologies (i.e., electrical, acoustics, magnetic) to enable multiparameter and multiplexed sensing.

(5) Comprehensive overviews of optical immunosensors.

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.

Folic acid (FA) and its other forms known as folates are small molecules vital for humans. The high demand for increasingly sensitive methods of measuring folate concentrations is due to the fact that abnormal levels of FA cause severe health disorders. Besides, folates are used as recognition molecules in targeted drug delivery. The majority of FA measuring techniques are rather expensive, laborious, sometimes not sufficiently sensitive and specific, and often employ consumables that are too costly to be single-use for routine medical diagnostics. Here, we present a procedure for transformation of a simple microscope cover glass slip without deposition of any metal or dielectric films into a cost-efficient chemosensor chip interrogated by spectral correlation interferometry for highly sensitive measurements of the concentration of small molecules, as well as a feasibility study of long-term monitoring of such molecules in a flow mode. The obtained chips were tested for folate detection. The highly specific and sensitive measurements can be performed in real-time in a wide dynamic range of 0.9–220,000 pM. The developed method and single-use consumables are promising for concentration measurements of low molecular weight substances in pharmaceuticals and in vitro diagnostics. Full article
