一般說明

产品可使用羧酸、羟基、酮、醚和/或氢进行功能化。
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,它们中的颜色中心不会发生光漂白或光闪烁。荧光纳米金刚石的优异性能以及生物相容性、大表面积等使其成为有前途的生物成像探针。
荧光纳米金刚石(FND)可以通过使合成金刚石纳米晶体经氦离子处理来制备。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,主要是因为在激光激发下从FND缺陷中心发出的光子可以轻松穿透组织。FND的发射非常稳定。[1]FND的平均尺寸为70 nm。

應用

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。[1][2]

Questions

  1. Hi, I'm looking at product 798169-5ML (70nm nanodiamonds). Approximately how many NVs per particle are there? I have a similar product from you (798169-mL) and it says it's more than 300NV's per particle. Is that the case for this product too?

    1 answer
    1. There are between 200 and 300 NV centers per particle.

      Helpful?
