(a,b) BRET ratio of CdSe/CdS core/shell and CdSe/CdS/ZnS core/shell/shell quantum rods (QR), respectively, conjugated to the thermostable variant of firefly luciferase Photinus pyralis (Ppy) for two different Ppy:QR ratios of 5 and 10. (c) Schematic depicting the microstructure of various QRs used in the dot-in-dot configuration has the lowest aspect ratio while the dot-in-rod has the highest. While loading capacity increases in dot-in-rod configuration, the proteins that are too far from the core CdSe contribute very little to the actual BRET [55]. Copyright 2012 American Chemical Society.
