Special Issue Information
Dear Colleagues,
Carbon dots (CDs) are carbon-based fluorescent nanoparticles. They possess an sp2-conjugated carbon core and a surface with multiple oxygen-containing species for various functionalities. Their simple synthesis, high photostability, and low toxicity have enabled them to become one of the most valuable and intriguing nanomaterials nowadays. Photoluminescence (PL) is one of the predominant properties of CDs in which researchers are most interested. Environmental sensing and bioimaging are the two primary applications built upon the unique PL properties of CDs. Further CDs are finding increasing applications as green catalysts.
This Special Issue will present comprehensive research from the synthesis and characterization of CDs to their applications in environmental sensing and bioimaging. Potential topics include, but are not limited to:
- Large-scale synthesis of CDs.
- Green synthesis of CDs with enhanced quantum yield and dependence of quantum yield on surface modification.
- Synthesis of CDs with long emission wavelength.
- Colloidal CDs for sensing imminent contaminants, such as per- and polyfluoroalkyl substances (PFAS).
- CDs that can differentiate multiple environmental contaminants without interference.
- Immobilization of colloid CDs into a solid matrix through electrospinning, etc.
- Portable sensing devices based on CDs.
- CDs as traditional cellular fluorescence agents.
- CDs as novel imaging agents for photoacoustics, magnetic resonance, computerized tomography, etc.
- CDs as green catalysts.

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. Nanomaterials is an international peer-reviewed open access semimonthly 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 2900 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.
