Special Issue Information

Dear Colleagues,

Wearable analytical technologies serve as a transformative alternative to clinical diagnostics that have attracted considerable attention since the medical care burden has been dramatically increased due to the aging global population and stressful modern lifestyles. To obtain diverse physiological and pathological information, these sensors can be worn through various ways, including glasses, contact lenses, face masks, dental braces, headsets, wristbands, smartwatches, bandages, patches, and textiles. The physical parameters and biochemical markers from different biofluids such as tears, saliva, breath, sweat, interstitial fluid, cerebrospinal fluid, semen, and urine can be detected in a noninvasive or minimally invasive manner. Continuous efforts in the exploration of robust, reliable, rapid, and efficient wearable sensors are highly desired to promote next-generation diagnostics and personalized medicine.

The Special Issue aims to publish a wide variety of topics that focus on the development of advanced responsive materials, the detection of biomarkers and physiological signals, and the construction of wearable and point-of-care analytical devices. We are delighted to invite submissions of research and review papers that help to advance the field of wearable biosensor technology and its building components, including, but not limited to, substrate materials, biomarker recognition, signal transducers, biofluid sampling, signal output, and readout.

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. 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 2700 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.

Ketones are well-known biomarkers of fat oxidation produced in the liver as a result of lipolysis. These biomarkers include acetoacetic acid and β-hydroxybutyric acid in the blood/urine and acetone in our breath and skin. Monitoring ketone production in the body is essential for people who use caloric intake deficit to reduce body weight or use ketogenic diets for wellness or therapeutic treatments. Current methods to monitor ketones include urine dipsticks, capillary blood monitors, and breath analyzers. However, these existing methods have certain disadvantages that preclude them from being used more widely. In this work, we introduce a novel acetone sensor device that can detect acetone levels in breath and overcome the drawbacks of existing sensing approaches. The critical element of the device is a robust sensor with the capability to measure acetone using a complementary metal oxide semiconductor (CMOS) chip and convenient data analysis from a red, green, and blue deconvolution imaging approach. The acetone sensor device demonstrated sensitivity of detection in the micromolar-concentration range, selectivity for detection of acetone in breath, and a lifetime stability of at least one month. The sensor device utility was probed with real tests on breath samples using an established blood ketone reference method. Full article
