Hybrid PEI25/HA15-30-CAN-Fe2O3 Nanoparticles

Hybrid 25kDa branched polyethyleneimine PEI25/Hyaluronic acid (15-30 kDa)-CAN-maghemite nanoparticles.


  • Functionalization: C3/4+ cation coordinative chemistries and polycationic polyNH2 / polyCOOH and /polyOH functional shells (reduced toxicity by charge reduction)
  • Posess novel orthogonal surface chemistry/engineering for drugs, polymers, ect.
  • Excellent for gene silencing applications (together with MRI tracking features)
  • Compatible with different modes (e.g., coordinative and covalent) of PEI toxicity reduction/NP surface engineering
