Silver nanodots, predominantly a near-IR emitter, can be instantly generated on a surface by silver cluster transfer. Kinetic trapping of ssDNA molecules on the surface limits the reorganization of the resulting silver nanodots for other silver nanodot emitters. Adjusting the freedom of the adsorbed ssDNA can tune the generation of various silver nanodots on the surface.
银纳米点主要是近红外辐射体，可以通过银团簇转移在表面上即时生成。表面上 ssDNA 分子的动力学捕获限制了所得银纳米点的重组，以形成其他银纳米点发射器。调整吸附 ssDNA 的自由度可以调节表面上各种银纳米点的生成。
