Abstract: The present disclosure belongs to the technical field of drug delivery and biomimetic structures inducing cell proliferation and differentiation, and in particular relates to a micro-nano medical stent for directional, quantitative and timed controlled release of drug and a preparation method thereof. The micro-nano medical stent provided by the present disclosure is composed of an ordered fiber structure electrospun as a skeleton layer and a disordered fiber structure electrospun as an ECM layer that can both load drugs. The micro-nano medical stent can achieve directional, quantitative and timed release of drugs.
