Because of excellent photoluminescence properties, robust chemical inertness, and low cytotoxicity of silicon nanoparticles (Si NPs), exploration of their applications in bioimaging is of great interest. Up to date, a method to synthesis Si NPs with high fluorescence quantum yield (QY) is still challenging. This situation limits the further applications of Si NPs. In this work, we report a mild, simple, and green one-pot method to synthesis N-doped fluorescent Si NPs with an ultrahigh QY up to 62%, using ethylenediaminetetraacetic acid disodium salt as an effective reductant. The obtained ultrabright Si NPs have properties such as relative small size (about 2 nm), water dispersibility, robust stability, and biocompatibility. The as-prepared Si NPs were further applied for cellular imaging with satisfactory results, indicating their great potential in bioimaging applications.

以乙二胺四乙酸二钠盐为有效还原剂一锅法合成用于细胞成像的超亮N掺杂荧光硅纳米粒子

由于硅纳米颗粒（Si NPs）具有出色的光致发光特性，强大的化学惰性和低细胞毒性，因此探索其在生物成像中的应用备受关注。迄今为止，合成具有高荧光量子产率（QY）的Si NP的方法仍然具有挑战性。这种情况限制了Si NP的进一步应用。在这项工作中，我们报告了一种温和，简单且绿色的一锅法，可以使用乙二胺四乙酸二钠盐作为有效的还原剂来合成Q值高达62％的N掺杂荧光Si NP。所获得的超亮Si NP具有诸如相对小的尺寸（约2nm），水分散性，稳健的稳定性和生物相容性的性质。所制备的Si NP进一步用于细胞成像，结果令人满意，
