Polymer composite gel with low molecular weight substances and the active component goethite, which provides controlled release of low molecular weight substances in visible light. Such a system releases low molecular weight substances slowly. The release rate can be increased by irradiation with visible light. As a result of irradiation, goethite desorbs small molecular substances adsorbed on its surface, as well as disintegrates the polymer gel, thus facilitating the escape of small molecular substances from the matrix.
For the controlled and sustained delivery of medications or other active substances through the skin for medical or therapeutic applications.
Ability to control drug release rate.
