  • X-ray ablation of hyaluronan hydrogels
    Patent number: 7903780
    Abstract: Disclosed is a method for ablating hyaluronan-based hydrogels with X-rays, the method comprising the steps of: (a) preparing hyaluronan-based hydrogels; and (b) performing X-ray irradiation to the hyaluronan-based hydrogels to induce a degradation of the hyaluronan-based hydrogels by a gel-to-sol transition during the X-ray irradiation. Disclosed is also a method for fabricating three-dimensional microchannels of hyaluronan hydrogels with a finely tunable X-ray ablation technique.
    Type: Grant
