Special Issue Information

Dear Colleagues,

Recent advances in the development of functional nanomaterials with unique physical and chemical properties have paved the way for the design of new biosensors for biomedical applications. A variety of emerging inorganic (e.g., quantum dots, carbon nanotubes, liquid metal alloys, and rare-earth nanoparticles) and organic (e.g., polymeric nanoparticles) nanomaterials, as well as hybrid nanomaterials, have become the basis for high-performance biosensors with enhanced sensitivity, selectivity, and robustness. Using these advanced nanomaterials as the core sensing elements, many nanosensors have been developed, including, but not limited to, silicon-based nanowire field-effect sensors for pH sensing, protein/DNA detection, and single virus detection; carbon dots-based photoluminescence sensors, electrochemiluminescence sensors, chemiluminescence sensors, and enzyme sensors; liposome-based nano biosensors for pesticide detection; and surface-enhanced Raman scattering nano-biosensors with different nanomaterials.

This Special Issue aims to highlight the recent advances in the development of functional nanomaterial-based biosensors and their applications in the biomedical field. Original research papers, reviews, and mini-review papers are all welcome.

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.

Wearable sweat biosensors for noninvasive monitoring of health parameters have attracted significant attention. Having these biosensors embedded in textile substrates can provide a convenient experience due to their soft and flexible nature that conforms to the skin, creating good contact for long-term use. These biosensors can be easily integrated with everyday clothing by using textile fabrication processes to enhance affordable and scalable manufacturing. Herein, a flexible electrochemical glucose sensor that can be screen-printed onto a textile substrate has been demonstrated. The screen-printed textile-based glucose biosensor achieved a linear response in the range of 20–1000 µM of glucose concentration and high sensitivity (18.41 µA mM−1 cm−2, R2 = 0.996). In addition, the biosensors show high selectivity toward glucose among other interfering analytes and excellent stability over 30 days of storage. The developed textile-based biosensor can serve as a platform for monitoring bio analytes in sweat, and it is expected to impact the next generation of wearable devices. Full article
