| 摘要 |
The lipids of this invention are derivatives of phosphatidyl choline having the general chemical formula: <IMAGE> (2) wherein at least one of R and R' is a polymerizable unsaturated alkyl group, acid or ester, wherein X includes an iminodiacetic acid in the polymerizable metal chelating lipid (2) and wherein z is an integer from 1-20 including 1 and 20. Lipid microstructures are formed by mixing the polymerizable metal chelating lipid monomers (2) with polymerizable non-chelating lipid monomers wherein X includes a non-chelating group, for example, -N+(CH3)3.
