近红外二区荧光成像

NIR-II fluorescence imaging

Near-infrared II (NIR-II) fluorescence imaging is a spectroscopic technique that utilizes fluorophores emitting in the 1000-1700 nm range to achieve high-resolution, deep-tissue optical imaging with reduced scattering and autofluorescence compared to visible or NIR-I imaging. / 近红外二区荧光成像是一种光谱技术，利用在1000-1700 nm范围内发射的荧光团实现高分辨率、深组织光学成像，相比可见光或近红外一区成像具有更低的散射和自荧光。
