摘要：

Bright particles: The optical properties of luminescent nanocrystals (quantum dots, QDs) can be exploited only if they are have an appropriate surface derivatization. A straightforward method is presented to encapsulate single QDs with a homogeneous silica shell, while retaining their high luminescence (see picture).
