【Abstract】 Due to painless, high bioavailability and easy drug delivery, microneedle is a new transdermal drug delivery method, which has been widely concerned. The classification and drug release mechanism of microneedles, the principle, advantages, disadvantages and application of photocuring 3D printing microneedle technology are introduced. The research progresses of photocuring 3D printing microneedles applied in skin disease treatment, insulin delivery, cancer treatment and aesthetic medicine are emphatically analyzed. The unique advantages of photocuring 3D printing microneedles are described, which can significantly improve the transdermal permeability of drugs, improve the accuracy of drug delivery and reduce systemic side effects. Finally, the current problems such as poor material biocompatibility, low drug loading and imperfect existing laws and regulations of photocuring 3D printing microneedles are discussed, and their development prospects are forecasted.更多还原
