Special Issue Information
Dear Colleagues,
Fluorescent nanomaterials have emerged as versatile tools in interdisciplinary research, especially in the analytical and biological sciences. For instance, fluorescent nanodiamonds (FNDs) possess a dense ensemble of negatively charged nitrogen–vacancy (NV–) centers that act as inherent fluorophores with exceptional optical and magnetic properties. When exposed to green-orange light, the NV– centers absorb at approximately 550 nm and emit bright fluorescence around 700 nm, with a prolonged lifetime exceeding 10 ns. These unique features of FNDs make them ideal for background-free imaging in tissue sections and long-term cell tracking, particularly in stem cell research. Furthermore, NV– of FNDs serve as photostable contrast agents, enabling super-resolution imaging via stimulated emission depletion (STED) and enhancing spatial resolution. The NV– centers' quantum characteristics also allow for optically detected magnetic resonance (ODMR) and ultrasensitive nanoscale temperature sensing through the pump-probe nano thermometry with sub-10 μs temporal resolution. Moreover, integrating FNDs with gold nanoparticles facilitates their use in localized hyperthermia applications.
Finally, the distinctive characteristics of fluorescent nanomaterials, including their high stability, adjustable emission spectra, and low toxicity, make them perfect for use in detecting and tracking biological molecules and monitoring environmental pollutants. Submissions related to any fluorescent nanomaterials are welcome for this special issue.

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. Materials 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 2600 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.
