• , retention, and low toxicity, as well as surface engineering with targeting moieties, can be used as a tool in enhancing the therapeutic efficacy of current approaches. Inorganic calcium phosphate nanoparticles have the potential to increase the therapeutic potential of antiproliferative drugs due to their

• excellent loading efficiency, biodegradable nature and controlled-release behaviour. Herein, we report a novel system of 5-fluorouracil (5-FU)-loaded calcium phosphate nanoparticles (CaP@5-FU NPs) synthesized via a reverse micelle method. The formation of monodispersed, spherical, crystalline nanoparticles

Calcium phosphate nanoparticles can serve as carriers for small and large biomolecules as well as for synthetic compounds. The nanoparticles were prepared and colloidally stabilized with either

Calcium phosphate nanoparticles have demonstrated to be very efficient to transport (bio)molecules into cells [8][9

The approach is based on the precipitation of calcium phosphate from IL/cellulose solutions rather than adding pre-fabricated calcium phosphate nanoparticles to the IL/cellulose solution and thus provides a rather simple, one-step

There are also a few reports on the mineralization of unmodified cellulose [11][24][25][26][27][28][29][30][31

• phosphate deposition on chitosan was equally successful, but without the need to photoactivate the mineralization reaction. Besides chitin and chitosan, carboxymethyl inulin (CMI) [20][21] and carboxymethyl cellulose (CMC) [22][23] have been studied as mineralization additives. Composites of CMC, calcium
