CMOS Sensor Microsystems

Dear Colleagues,

Complementary metal-oxide-semiconductor (CMOS)-based microsystems for biological and medical sensing, imaging and diagnostics have undergone tremendous progress over the past several years attracting multidisciplinary research and development efforts that encompass microelectronics, photonics, nanomaterials, biologics, microfluidics, and microfabricated devices. There are several benefits to using standard CMOS fabrication processes for sensor development as it would allow one to produce low cost, low power, rapid response, mass-producible and miniaturized systems with on-chip signal processing. ISFETs, BioFETs, photodiodes and cantilevers are some example devices that are integrated on CMOS chips for various biosensing applications. There are several examples of CMOS chips integrated with metal microelectrode arrays and silicon based probes for neurological applications. We notice significant interest for integration of nanowires, nanoparticles and other nanoscale materials and structures on CMOS platforms towards the development of highly sensitive and selective biosensors. More recently, emerging research and development topics include CMOS lab-on-chip systems for high-throughput analysis and diagnostics and smartphone enabled wearable/portable biosensors and zero-cost diagnostics platforms.

This special issue will be dedicated to promoting the wide range of biological and medical sensors that employ CMOS detection and signal processing platforms. The applications areas include medical diagnostics, clinical analysis, point-of-care sensing, wearable/implantable devices, environmental sensing, food safety and national security.

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. Biosensors 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 2200 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.
