From nanometric to giant polyion complex micelles via a hierarchical assembly of dendrimers

PIC (polyion complex) micelles prepared from oppositely charged block copolymers have typical diameters of about 30-50 nm. Attempts to control their size have proven elusive. Since the presence of a neutral hydrophilic block in the copolymers, such as poly(ethylene glycol) (PEG), allows confining th...

Descrição
Resumo:PIC (polyion complex) micelles prepared from oppositely charged block copolymers have typical diameters of about 30-50 nm. Attempts to control their size have proven elusive. Since the presence of a neutral hydrophilic block in the copolymers, such as poly(ethylene glycol) (PEG), allows confining the charged blocks within a core, reducing PEGylation was expected to produce larger micelles to accommodate fewer/smaller PEG chains at the corona.
