在荧光纳米金刚石中，金刚石晶格中的氮空位中心提供荧光；与量子点或有机染料不同，这些中心的颜色不会发生光漂白或光致发光。这些突出的性能以及荧光纳米金刚石的生物相容性，大的表面积等。因此它们成为有前途的生物成像探针。荧光纳米金刚石 (FND) 可以通过将人造金刚石纳米晶置于氦离子下制备。FND 具有生物相容性，其表面易于功能化。它是生物成像中非常有用的工具，主要是因为激光激发时从 FND 的缺陷中心发出的光子很容易穿透组织。FNDs 的发射非常稳定。FND 的平均尺寸是 120 nm 应用 FND 的潜在应用是作为体内纳米探针用于生物成像、细胞标记和细胞追踪。 In fluorescent nanodiamonds, the nitrogen vacancy centers in the diamond lattice provide the fluorescence; unlike the quantum dots or organic dyes, the color centers in these don′t photobleach or photoblink. These outstanding properties of fluorescent nanodiamonds along with their biocompatibility, large surface area etc. make them promising bioimaging probes.Fluorescent nanodiamonds (FNDs) can be prepared by subjecting synthetic diamond nanocrystallites to helium ions. FND is biocompatible and its surface can be easily functionalized. It is a very useful tool in bioimaging mainly because the photons emitted from the defect centers of FND upon laser excitation can easily penetrate the tissue. The emission from FNDs is extremely stable. The average size of the FNDs is 120 nm.Product can be functionalized with carboxylic acid, hydroxyl, ketones, ethers, and/or hydrogen.Potential uses of FNDs are as in vivo nanoprobe for bioimaging, cell labelling and cell tracking.
