Abstract
The invention provides a universal nanoscale electrospining regionalization method. The universal nanoscale electrospining regionalization method comprises that according to thermal melting properties of an unpolymerized SU8 photoresist, through exposure under ultraviolet exposure conditions, a SU8 photoresist coated on a glass support plate so that polymerization and non-polymerization zones are formed; the treated SU8 photoresist is arranged under an electrostatic spinning device so that an electrically spun layer is formed on the surface of the SU8 photoresist; the treated SU8 photoresist is arranged in an oven and then is heated so that the unpolymerized SU8 photoresist are melted into a liquid and the volume of the molten SU8 photoresist is increased and the molten SU8 photoresist wraps electrically spun threads; and the treated SU8 photoresist is cooled at a room temperature and is subjected to ultraviolet exposure so that the unpolymerized SU8 photoresist is polymerized and electrospining regionalization is realized. The universal nanoscale electrospining regionalization method has the advantages that nanoscale electrospining patterns obtained by the universal nanoscale electrospining regionalization method can provide an application platform having a potential for tissue engineering and regenerative medicine engineering; processes are simple; controllability is strong; and the universal nanoscale electrospining regionalization method can combine with novel technologies such as microfluidic easily.
