Abstract
The present invention relates to a method for remotely controlling a sol-gel transition of hydrogels and a method for delivering a drug using the same. More specifically, the invention relates to a method of remotely controlling a sol-gel transition of polyethylene glycol (PEG)-containing hydrogels—three-dimensional networks of crosslinked polymer chains—by X-ray irradiation, and relates to a method for delivering a drug using the same.
Claims12
A method for remotely controlling a sol-gel transition of hydrogels, the method comprising the steps of:
- (a) preparing hydrogels;
- and
- (b) irradiating X-rays to the hydrogels so as to trigger a gel-to-sol transition of the hydrogels.
A method for delivering drugs using a remote control of a sol-gel transition of hydrogels, the method comprising the steps of:
- (a) preparing a suspension of hydrogels and drugs;
- (b) administrating the suspension into a living body to transport the suspension to a target portion of the living body;
- and
- (c) irradiating X-rays to the transported suspension so as to trigger a gel-to-sol transition of the hydrogels in the transported suspension, and thereby releasing the drugs from the transported suspension into the target portion of the living body.
