    摘要: Paramagnetic, amphiphilic, biocompatible polymers were prepared comprising a carbonate repeat unit bearing a paramagnetic organic radical, more specifically a nitroxyl radical. The radical polymers can be produced in one step from a precursor polymer bearing an active ester side chain by treating the precursor polymer with a radical-bearing nucleophile. The precursor polymer can be prepared by organocatalyzed catalyzed ring opening polymerization (ROP) of a cyclic carbonate monomer bearing an active ester side chain. The radical polymers can be non-toxic and partially biodegradable. The radical polymers have utility as contrast enhancing agents in a medical imaging application and/or as therapeutic agents for treating a medical condition. The radical polymers can also serve as carriers for therapeutic agents (e.g., drugs) and/or medical image enhancing agents (e.g., NIRF dyes).

    摘要: The invention relates to compositions of DOTA derivative compounds, lanthanoid-DOTA derivative molecular complex, and lanthanoid-complex encapsulated solid lipid particles or capsules, and methods of making and using the compositions. The solid lipid particles or capsules contain micelle cores stabilized by a hyperbranched polymer shell based from a crosslinked DOTA derivative compound or crosslinked lanthanoid-DOTA derivative complex. These solid lipid particles or capsules can be used in various applications, such as contrast agents or drug delivery vehicles.

    摘要: Disclosed are compositions that contain a plurality of biocompatible self-assembling molecules that transform from isolated molecules or spherical micelles in the circulation into cylindrical nanofibers in the acidic extracellular environment of tumors which can be used to achieve a higher relative concentration of imaging, drug delivery, or radiotherapeutic agents at the tumor site compared to non-tumor tissues. This transition is rapid and reversible, indicating the system is in thermodynamic equilibrium.
