Development of superior nanotheranostic agents with indocyanine green-conjugated poly(styrene-alt-maleic acid) nanoparticles for tumor imaging and phototherapy

“…18 One strategy to avoid ICG aggregation is to encapsulate ICG non-covalently in NPs, 19 including liposome NPs, 20 polymeric NPs, 21,22 mesoporous silica NPs, 23 and calcium phosphate NPs. 24 However, the non-covalent encapsulation of fluorescent monomers in NPs inevitably leads to molecular aggregation because monomers can still move and aggregate freely inside NPs. 25 In contrast, the covalent conjugation of ICG enlarges the steric hindrance to avoid ICG aggregation.…”
