23 Jul Surface modifying method for biological material
Abstract
The invention discloses a surface modifying method for a biological material. The surface modifying method comprises the step of carrying out oxygen gas plasma activation treatment on the material surface and then carrying out surface self-assembling; then, alternatively immobilizing chemical molecules with different functional groups in sequence by adopting a micro-contact printing technology, so that the biological active molecules with different biological functions are immobilized on the material surface to obtain the biological material with multifunctional biological activity. The method disclosed by the invention is adopted to treat the material surface, so that multifunctional biological activity is provided for the material surface, and therefore, the surface modifying method is applied to the fields such as biological materials, tissue engineering and implantable medical device research.
