Microfluidic Paper-Based Chips for Detection: Current Status, Challenges and Perspectives

Dear Colleagues,

Microfluidic paper-based chips (μPCs) are miniature laboratory analysis systems that utilize a paper substrate for a microfluidic system instead of the traditional substrates (e.g., silicon and polymers). Due to their low cost, easy fabrication process and portability, they have been widely used in a diverse range of scientific fields, including food safety, environmental residue pollution, pathogen detection, etc. In recent years, significant research has been devoted to the study of microfluidic paper-based chips, including chip structures, sensor mechanisms, targets types, detection devices and integration systems. The rapid development in this field seen thus far indicates μPCs are swiftly gaining popularity as promising analytical platforms.  

For this particular issue, we are inviting the submission of original research papers and review articles to engender a discussion on the current status, challenges and prospects of microfluidic paper-based chips. We hope this issue will initiate a collaborative effort to encourage advancements in microfluidic technology and in solving detection and diagnosis problems. This paper will cover all aspects of microfluidic paper-based chips, including, but not limited to, the latest developments in the following areas: new μPCs design, theoretic analysis of microfluidics, hybrid sensing materials, novel sensing strategies, multiplex sensor arrays, emerging pollutants or targets and new biomarkers and other related technologies. If you are unsure whether your work falls within the scope of this Special Issue, please contact the Editor of the Special Issue before submission.

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 250 words) can be sent to the Editorial Office for assessment.

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. Sensors is an international peer-reviewed open access semimonthly 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.
