Calcium Phosphhate andd Other Salts

Calcium phosphate (CaPi) co-precipitates with DNA to form nanoparticles that enter cells via endocytosis. While simple and inexpensive, CaPi nanoparticles tend to aggregate and have inconsistent transfection efficiency. Innovations include block copolymer-stabilized CaPi and carbonate-apatite composites that improve stability and dissolution in endosomes. Newer salts like magnesium phosphate and strontium phosphate are being explored for their slower dissolution rates, allowing more controlled release. These systems are primarily used for in vitro transfections, but optimization may allow in vivo applications.
