Nanodiamond is a unique class of carbon nanomaterial with crystal sizes ranging from ~3 nm to several hundred nm. Nanodiamond has favorable properties for biomedical applications including non-toxic, biocompatible, and flexible surfaces for a wide range of functionalization. Moreover, color centers (atomic size point defects in nanodiamond) give the nanodiamonds unique photonic and spin properties and are rapidly driving the development of nanoscale quantum sensing capabilities. In this symposium the broader community will discuss how production methods can affect the size, morphology, surface chemistry of nanodiamonds and the corresponding yield and orientation of color centers. Understanding and developing advanced nanodiamond processing methods promises to enable nanodiamond materials with improved photonic and spin properties. This is of critical importance to both sensing and communication applications, where both longer spin coherence times and brighter single photon emission are needed. In addition, rapidly growing interests in nanodiamonds have also been driven by applications in nanotherapies (antibacterial agents, implantation coating, bone implant, etc.), drug delivery (cancer treatment, vaccination, stem cell therapy, etc.) and medical imaging. The large breadth of research has demonstrated that nanodiamonds can be used as a multi-modal platform for diagnostics and delivery of both traditional and emerging therapeutic molecules. Nanodiamonds have additional advantages of uniform shape, hardness, non-porosity, and unique surface chemistries that lead to their applications as nanocomposites. This symposium provides a platform for the presentation of recent advances of nanodiamond synthesis, functionalization, quantum sensing, biomedical theranostic applications, and other novel applications like catalysis, photoelectrocatalysis, and nanocomposites.
