Title:
CAVITATION SEED FOR DRUG DELIVERY, AND DRUG DELIVERY METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/190703
Kind Code:
A1
Abstract:
A cavitation seed for drug delivery, and a drug delivery method using the same are disclosed. The cavitation seed according to the present invention comprises: a shell which forms the outer surface thereof to maintain the outer shape thereof within a fluid; and a core which is located inside the shell to determine buoyancy of the cavitation seed within the fluid. The cavitation seed can improve an effect of delivering a drug into a body since cavitation is induced by ultrasound at a position close to the epidermis. In addition, the cavitation seed can be applied in the delivery of various drugs as well as skin cosmetics, such as skin whitening agents, depilatories, hair restorers and skin fillers, skin analgesics, local anesthetics, agents for genetic diseases such as psoriasis, and agents for treatment of skin disease such as skin cancer.
