Dear Colleagues,

Imaging and sensing tools are indispensable for scientific discovery and innovation. The field is undergoing a profound transformation. The price and size of image sensors, light sources, and optical components have been significantly reduced. The revolution in smartphones and other consumer digital devices have placed low-cost, high-quality imaging systems in the hands of billions of people. Device fabrication and prototyping is becoming increasingly inexpensive and faster than ever with 3D printing. With these trends, various cost-effective, field-portable, and easy-to-use imaging and sensing tools are emerging. Advanced microscopy and spectroscopy measurements can now be rapidly performed on palm-size or wearable devices. Using such miniature devices, personal health can be monitored in real time and continuous fashion via consumer-level health measurement and diagnostic platforms, especially useful in the developing world where diagnostic technologies are often both limited and expensive. This Special Issue seeks to showcase recent development of mobile imaging and sensing technologies and their applications for point-of-care (POC) diagnostics, chemical/biological sensing, and environmental monitoring. It aims to form a collection of original research papers, short communications, and review articles that focus on novel methodological developments of miniaturized microscopes, mobile phone-based devices, lab-on-a-chip microscopes, handheld/wearable sensors, and utilization of such systems for a variety of promising detection and sensing applications.

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 papers will be 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 1200 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.
