羧化红色荧光纳米金刚石：Carboxylated Red Fluorescent Nanodiamond

Biofunctionalized fluorescent nanodiamonds are infinitely photostable labels for fluorescent and multiphoton microscopy applicable to cellular tracking and long-term observation of biological processes in the same fields of view in live cell-imaging and fixed cells. Protein, antibody, biologically active organic molecules, and custom functionalizations are possible. We provide nanodiamonds with nitrogen-vacancy (NV) centers with red-to-near-infrared fluorescence, NVN centers with green fluorescence, and novel particles available only at Adamas with a combination of NV and NVN centers within a single particle with visual yellow fluorescence. Fluorescence from NV centers can be magnetically modulated providing a means to eliminate the fluorescent background by image subtraction and to significantly enhance the signal-to-noise ratio. This property can be very useful in future biosensing applications, for example in clinical diagnostics such as lateral flow assays (LFA). Relevant applications also include super-resolution microscopy, multiphoton microscopy, time-gated microscopy and correlative microscopy.

Fluorescent nanodiamonds are a chemically robust, infinitely photostable, and biocompatible fluorophore with a range of functional surface chemistries. Relevant applications include fiducial marking, super-resolution microscopy, multiphoton microscopy, time-gated microscopy, and correlative microscopy.

Below is our selection of nitrogen-vacancy (NV) nanodiamonds centers with red-to-near-infrared fluorescence with a variety of surface functionalities. Negatively charged nitrogen-vacancy (NV-) centers possess an electron spin with unique magneto-optical properties: the spin state can be detected optically via optically detected magnetic resonance (ODMR). In turn, the spin state is highly sensitive to the surrounding environment so that changes in the environment can be detected via changes in nitrogen-vacancy (NV) fluorescence. Based on these properties, our customers develop nanodiamond-based quantum sensors of magnetic fields, electric currents, temperature, free radicals, and other phenomena.

如图是我们选择的具有红色至近红外荧光且具有多种表面功能的氮空位 (NV) 纳米金刚石中心。带负电的氮空位 (NV-) 中心具有具有独特磁光特性的电子自旋：可以通过光学检测磁共振 (ODMR) 光学检测自旋状态。反过来，自旋态对周围环境高度敏感，因此可以通过氮空位 (NV) 荧光的变化来检测环境的变化。基于这些特性，我们的客户开发了基于纳米金刚石的磁场、电流、温度、自由基和其他现象的量子传感器。
