Abstract

New biocompatible complexes based on manganese-doped core/shell ZnS/ZnS quantum dots (ZnS:Mn2+/ZnS) and drug "Photoditazin" were formed and compared to traditional complexes with CdSe/ZnS quantum dots. Complexes with ZnS:Mn/ZnS quantum dots show some advantages in their photophysical properties. At the same time they demonstrate evident difference in their photophysical properties that may be associated with various location of trap states in places where drug molecule bounds with quantum dot.
