Diamond, the most famed of all gemstones, is unique in many ways. However, beyond the sparkle, diamonds have many unique properties for copious applications. In particular, nanoscale diamond particles, generally known as nanodiamonds (NDs), have several outstanding material qualities, offering a wide range of potential for basic science and industrial applications. The practical applications of the quantum NDs are highly dependent on obtaining a well-defined surface through cleaning. Here, this talk will first present a simple, reliable, and reproducible purification method, namely, the salt-assisted air oxidation treatment, which enables scale-up manufacturing of clean NDs. At the same time, it is discovered that NDs could work as an effective agent against oral infections. These findings will significantly enhance the scope of these little gemstones in diverse scientific and industrial fields, particularly in demanding areas such as biomedical and quantum sensing.
