Method for remotely controlling a sol-gel transition of hydrogel and method for delivering a drug using the same

摘要

The present invention includes the steps of preparing a hydrogel; And provides a phase change of the hydrogel remote control method comprising the step of irradiating the X- ray to the hydrogel to induce a phase change in the sol gel of the hydrogel. In another aspect, the present invention is to prepare a drug mixed with a hydrogel drug suspension; phase change of the sol and the gel of the hydrogel in the drug delivery suspension; step for delivery to a target site in vivo by administration of the drug suspension the derived so as to the release the drug to the target site, and provides a phase change of the drug delivery hydrogel comprising the step of irradiating the X- ray in suspension drug delivery method using the remote control. According to the present invention, to provide a high through-sex benefits, applicable to a thick object, such as a human body, and opens up the possibility of new and exciting technology.
