Research Abstract

For clinical application of induction heating cancer therapy, specific accumulation of magnetic nanoparticles to cancer tissue is a indispensable fundamental technique. Conventional approach, viz. tumor specific antibody conjugate nanoparticle, confer only 0.2mg/g tumor accumulation. Intending to precipitate more particles to tumor, we have tried to innovate multiple step administration of biotinaized and avidinaized magnetic nanoparticles alternateively. This approach, however, failed to accumulate nanoparticles to tumor, due to non-specific trap by Kpper cells in liver. When we tried alternative approach, i.e. decoration of nonparticle surface with original unique PEG, 0.58mg/g tumor accumulation have achieved.
