荧光纳米金刚石

Fluorescent nanodiamond (nitrogen vacancy ~3 ppm NV centers, 140 nm avg. part. size, biotin functionalized, PEG 3000 coated, 1 mg/mL in deionized water), a biocompatible carbon-based nanomaterial, has interesting properties like excellent photostability, low toxicity and facile surface functionalizability. It can be used for a variety of biological applications.

Nanodiamonds (NDs) containing NV color centers exhibit fluorescence in red/near infra-red (NIR) region. The fluorescence in NDs originates from nitrogen vacancies and, unlike quantum dots and organic dyes, NDs do not photobleach. Fluorescent NDs find applications in background-free imaging, flow cytometry, super-resolution imaging etc. Our biotin functionalized NDs are ideal for attachment with streptavidin modified targets.
