摘要：
The present invention relates to a triple-layer multilayer thin film, which solves a problem of the activity of a growth factor being reduced rapidly due to low stability and enables a continuous release of growth factors maintaining activity. The multilayer thin film of the present invention includes at least one triple-layer which comprises a positive charge polymer layer, a negative charge polymer layer and a growth factor layer, and a content of the growth factor contained in the growth factor layer is 40-50 ng/cm^2.COPYRIGHT KIPO 2018본 발명은 삼중층 다층박막에 관한 것으로, 낮은 안정성으로 인해 성장인자의 활성도가 급감하는 문제점을 해결하고, 활성도를 유지한 성장인자의 지속적인 방출이 가능하여 세포 배양에 직접적으로 적용할 수 있는 다층박막을 제공할 수 있다.
