Novel Ti

Magnetic composite particles immobilized with metal affinity ions show high potential in the phosphoproteome mass-spectrometric (MS) analysis. However, the preparation of this kind of material still suffers from a complicated synthesis procedure and high cost. In this work, the magnetic nanostructured composite microspheres (MPCS) incorporated into N-methylene phosphonic chitosan were first fabricated via a facile one-pot synthesis strategy and titanium ions (Ti
