Nitrogen-doped carbon dots (CDs) have been produced by a new facile "bottom-up" synthesis, using the room-temperature reaction between acetonitrile and sodium-naphthalene. The obtained hydrophobic CDs are monodisperse (∼2.6 nm) and present an excitation-independent emission at ∼588 nm with a small full width at half-maximum (FWHM) of ∼52 nm. The CDs can be simply modified to be hydrosoluble and have been demonstrated to be an efficient red-emission agent for both in vivo and in vitro bioimaging.
通过乙腈与萘钠之间的室温反应，采用一种新的简便“自下而上”合成方法制备了氮掺杂碳点（CDs）。所获得的疏水性碳点是单分散的（约2.6纳米），在约588纳米处呈现与激发无关的发射，半高宽（FWHM）约为52纳米。这些碳点可以简单地改性为水溶性，并且已被证明是一种用于体内和体外生物成像的高效红色发射剂。
