We demonstrate a novel process for selective binding of single semiconductor core-shell quantum dots (QDs) to transparent all-dielectric (glass) substrates with nanoscale resolution. This is accomplished by defining a mask via electron-beam lithography (EBL) followed by functionalization of only the exposed areas of the substrate with a heterobifunctional linker, while applying a binding inhibitor to all other areas. Single QD blinking is clearly observed for several QD functionalized sites. Our approach is compatible with standard two-step EBL nanofabrication schemes and it does not rely on the presence of metals, making it suitable for coupling QDs to all-dielectric nanoresonators.
