Drug induced micellization into ultra-high capacity and stable curcumin nanoformulations: Comparing in vitro 2D and 3D-tumor model of triple-negative breast cancer

Abstract

This manuscript describes a ultra-high loaded nanoformulation of curcumin. This compound is extremely water insoluble but could be dissolved using poly(2-oxazoline)/poly(2-oxazine) based polymer amphiphiles. The resulting formulations were thoroughly characterized in solution and solid form by NMR, dynamic light scattering, electron microscopy, HPLC zeta potential measurements, XRD, respectively. Biological activity was ensured and compared in 2D and 3D cell culture.
