FIGURE 3

An overview of the in-depth structure of the quantum dot based nano-constructs. The figure illustrates that these nano-structures comprise an inorganic core, inorganic shell and an additional aqueous layer of polymers. The outer layer is layered with polymer or attached to desired peptide ligand/antibody for specific targeting.
