Copolymer containing cyclic nitroxide radical and trialkoxysilyl in side chain, and use thereof |
| abstract |
A copolymer which includes hydrophilic and hydrophobic blocks, which can form nanoparticles in which a physiologically active substance can be efficiently packaged therein and which are stable under acidic conditions. The hydrophilic segment of the copolymer is composed of polyethylene glycol (PEG) and the hydrophobic segment is composed of polystyrene. The hydrophobic segment has a side chain, and the side chain has ends to which a cyclic nitroxide radical having a radical scavenging function and a trialkoxysilane are covalently bonded. |
