Paper Title:
Folic Acid Immobilized Ferrimagnetic DP-Bioglass to Target Tumor Cell for Cancer Hyperthermia Treatment
  Abstract

DP-bioglass is one of biodegradable glasses, which can be used as bioactive material in soft tissue and bone. It was often used in orthopedy and plastic surgery. Recently, bioglass was also used as a carrier for drug and gene delivery systems. Additionally, ferrimagnetic DP-bioglass can be potential candidates for magnetic induction hyperthermia, by using a magnetic field. The aim of this work is the preparation and characterization of surface-modified ferrimagnetic DP-bioglass. First DP-bioglass has to be surface-modified with polyethylene glycol (PEG) and folic acid (FA) to improve its intracellular uptake and ability to target specific cells. PEG-FA complex was synthesized using carbodiimide (DCC) to link PEG with FA. Then PEG-FA complex were immobilized on the surface of DP-bioglass by using amino-silane (AEAPS) as a coupling agent. Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (1H NMR), and thermogravimetric analysis (TGA) was used to demonstrate this immobilization process. In biological study showed that immobilized ferromagnetic DP-bioglass with PEG-FA was non-cytotoxicity and significantly enhanced the intracellular uptake of DP-bioglass by target cells.
