Special Issue Information
Dear Colleagues,
Exosomes are nanometer-scale membrane vesicles initially thought to be cellular debris, but now increasingly appreciated as key vehicles of cell-to-cell communication. Shed by most cells, exosomes carry a valuable cargo of proteins and nucleic acids signaling the parent cell’s state. Present in nearly all bodily fluids, they offer tremendous potential for disease diagnosis and prognosis, particularly cancer, through minimally-invasive liquid biopsy. They could also be used as vaccine candidates and drug carriers, delivering therapeutic agents to target cells. Research on exosomes continues to grow, with exciting discoveries gradually revealing their physiological significance and suggesting the potential for far-reaching clinical impact. The pace of discovery is limited, however, by the lack of effective preparatory and analytical techniques. Methods of exosome isolation often include ultracentrifugation, co-precipitation, filtration, size-exclusion chromatography, and immunoaffinity. However, these methods suffer from bulky and costly instrumentation, as well as lengthy and laborious processing. Importantly, major sample loss including low yield and recovery is a fundamental issue hindering many of these conventional methods. Microdevices by virtue of their small size can minimize sample loss while enhancing the purity and yield of exosomes isolated from complex biofluids. We dedicate this Special Issue to microdevices promoting a wave of progress in exosome research and clinical 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 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.
