ABSTRACT:
A biodegradable carrier is produced for preservation and/or controlled delivery of biologically active agents where the biodegradable carrier is a silica xerogel which is made from water and silane by using acid or base as a catalyst, and biologically active agents in the biodegradable carrier are infecting and/or transfecting viruses. Silica xerogel material can be pharmaceutically acceptable and it can be used as a medicine.
