Dear Colleagues,

In last ten years, the development of point-of-care (POC) biosensing methods has attracted tremendous attention.

Because of the features of rapid response, low price, easy operation, etc., these newly developed biosensing strategy are promising the way toward the next generation of analytical measurement and diagnostics of components of interest, such as heavy metals, small molecules, peptides, proteins, nucleic acid, cells, etc. Technically, three significant things need to be taken into consideration: the design of the devices, the detection of conjugate-forming mechanisms, and the detection methods. Specifically, these POC biosensing methods are based on but not limited to traditional methods such as electrochemistry, UV–vis spectroscopy, fluorescence, and electrochemiluminescence. Although many types of carry-on instruments are invented, they are still not simple (cheap) enough for patients with different education background (financial situation) to use. Therefore, these POC biosensing technologies still need to be improved in practice, to allow their commercialization . Accordingly, in this Special Issue, we would like to showcase review articles and research papers which focus on: (1) the design of new devices, (2) new biosensing mechanisms, (3) new detection techniques, and/or (4) improvement of existent POC biosensors.

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. Micromachines 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 2600 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.
