Synthesis, Characterization, and Application of Advanced Carbon Dots in Biomedical Engineering

Dear Colleagues,

Carbon dots (CDs) represent a broad category encompassing nanoscale photoluminescent carbon materials, which are a growing subclass of nanoparticles characterized by quasi-spherical or amorphous structures. This category includes carbon nanodots (CNDs), carbonized polymer dots (CPDs), carbon quantum dots (CQDs), and graphene quantum dots (GQDs). In recent years, the design of CDs with various functions and their extensive application have become hot topics in biomedical engineering. Nevertheless, innovative CDs synthesized through various approaches are being reported constantly. Challenging issues in developing CDs with excellent performance include poor controllability, low yield, fluorescence aggregation quenching, and poor photoluminescence efficiency. More importantly, the mechanism and efficiency of CDs in biomedical engineering are still unclear, such as application in biosensors, tissue imaging, cancer treatment, antibacterial agents, neurodegenerative diseases, and immunotherapy. Therefore, new synthesis and characterization methods of CDs are being proposed, the properties of CDs and other functional components are being combined to achieve synergistic treatment, and various physical and chemical properties (e.g., sound, light, thermal, electric, and magnetic) of CDs are being used to solve the related pathogenic factors of diseases. In addition, the mechanisms of synthesis and applications of CDs should be studied in-depth. Authors are welcome to cover any of the issues mentioned above according to their expertise.

We hope you will contribute to this well-focused Special Issue, and we would be grateful if you could forward this information to friends and colleagues that might be interested in this topic.

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. ChemEngineering 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 1600 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.
