Provided herein are polymer-stabilized CaP nanoparticle formulations and related methods of manufacture. In certain embodiments, the methods reliably and selectively form nanoparticles with homogenous size, charge, and morphology. The CaP nanoparticles include calcium ions and phosphate ions with an ionic polymer, thereby forming stable hybrid nanoparticles. The CaP nanoparticle formulations include powders, suspensions and injectable pastes. According to various embodiments, the polymer-stabilized CaP nanoparticles may be polycation-stabilized (CaP/polymer(+) nanoparticles) or polyanion-stabilized (CaP/polymer(−) nanoparticles). The CaP/polymer nanoparticles can be freeze-dried and stored for months with no loss of properties or changes to their morphology.

Injectable pastes based on oppositely charged polymer/calcium phosphate nanoparticles

Stable, macroscopic single-crystal chiral liquid crystal compositions are described. The compositions include a single-crystal chiral liquid crystal material on a patterned surface. The patterned surface seeds a particular crystallographic orientation at the substrate-liquid crystal interface. Also described are methods of forming the single-crystal chiral liquid crystal compositions.
