Abstract

Porous titanium phosphate (TiP) nanoparticles with high water solubility have been synthesized by using the surfactant sodium dodecyl sulfate (SDS) as the structure-directing agent. The TiP nanoparticles can be functionalized with Cd²⁺ and can be further used as labels for electrochemical detection of proteins due to their excellent ion-exchange property.
