On page 1843 , Dong Soo Lee, Yoon‐Sik Lee, and co‐workers investigate very bright quantum dot (QD)‐based probes for effective bioimaging. Silica‐coated, QD‐embedded silica nanoparticles (Si@QDs@Si NPs) containing QDs composed of CdSe@ZnS (core‐shell) are prepared to compare the structure‐based advantages with single QDs having similar quantum yields. The excellence of Si@QDs@Si NPs is illustrated by significantly enhanced fluorescence signals. The more advanced version of QDs‐based silica nanoparticles containing multishell QDs is prepared without significant loss of quantum yield during surface modification.
