The amphiphilic diblock copolymer poly ( epsilon - caprolactone ) - b - poly ( ethylene oxide ) ( PCL - b - PEO ) was first conjugated with the cyclic ( Arginine - Glycine - Aspartic acid - d - Phenylalanine - Lysine ) ( c ( RGDfK ) ) and fluorescein isothiocyannate ( FITC ) via the functional terminal groups of hydrophilic block , and then assembled into micelles .
 Chemical: poly ( epsilon - caprolactone ) - b - poly ( ethylene oxide ); Chemical: PCL - b - PEO; Chemical: cyclic ( Arginine - Glycine - Aspartic acid - d - Phenylalanine - Lysine ); Chemical: fluorescein isothiocyannate; Chemical: FITC
