Polymer micelles as drug carriers

Block copolymer micelles are composed of polymer chains with sequences of hydrophilic and hydrophobic blocks. In a dilute aqueous solution, they form spherical or cylindrical nano-objects comprised of several chains with a hydrophobic core and extended hydrophilic corona. Lipophilic drugs can be dissolved in the core of these micelles, while the corona will assure solubility […]

Degradation versus self-assembly of block copolymer micelles

A. Muratov and V. A. Baulin

Langmuir, 28, 3071-3076 (2012)

The stability of micelles self-assembled from block co-polymers can be altered by the degradation of the blocks. Slow degradation shifts the equilibrium size distribution of block co-polymer micelles and changes their properties. The quasi-equilibrium scaling theory shows that the degradation of hydrophobic blocks in the core of […]
