含有NV色心的纳米金刚石（ND）在红色/近红外（NIR）区域显示荧光。NDs中的荧光来源于氮空位，与量子点和有机染料不同，NDs不会光漂白。荧光NDs在无背景成像、流式细胞术、超分辨率成像等领域有应用。我们的PEG涂层羧基官能化NDs非常适合使用EDC化学附着生物分子。ND上的PEG间隔物减少了生物分子之间的空间位阻。 Nanodiamonds (NDs) containing NV color centres 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 PEG coated carboxyl functionalized NDs are well suited for attachment of biomolecules using EDC chemistry. The presence PEG spacer on NDs reduces the steric hindrance among the biomolecules. Description Fluorescent nanodiamond (nitrogen vacancy ~3 ppm NV centers, 140 nm avg. part. size, carboxylic acid functionalized, PEG 3000 coated, 1 mg/mL in deionized water), a biocompatible carbon-based nanomaterial, has interesting properties like excellent photostability, low toxic and facile surface functionalizability. It can be used for a variety of biological applications.Nanodiamonds (NDs) containing NV color centres exhibit fluorescence in red/near infra-red (NIR) region.
