Abstract

The present invention refers to release matrices which include a material that can be released in a controlled way or with predefined kinetics into a surrounding medium, reaction vessels comprising said release matrices, and release system further comprising a medium which is able to dissolve the embedded material. The present invention further refers to the use of release matrices in several applications and the production method for such matrices. The present invention also relates to a method that al lows control of the release rate of materials from polymer matrices with several factors.
