ABSTRACT:
The present invention relates to a nylon capsule to whose pore portion is applied a bimolecular membrane so that the capsule can respond to pH.
The nylon capsule accommodates various matters such that they can be released into the outside depending on the change of pH. The nylon capsule is useful, for example, for the missile treatment of anticancer drugs, and as a gradually-releasing microcapsule.
