    摘要: The present invention relates to a method of modulating a release of biomolecules having heparin-binding affinity, and more specifically, to a method of modulating a release of biomolecules having heparin-binding affinity, using thiolated heparin adsorbed on metal surface. According to the present invention, it is possible to modulate various biomolecules having heparin-binding affinity such as growth factors spatiotemporally by external electrical stimulations, without causing cytotoxicity and having deteriorating effects on cell activity. Thus, the present invention can be applied for various biomedical and biotechnical fields including drug delivery, biosensor, and cell culture.
