biological species in inorganic gels is a promising alternative to natural or
synthetic polymers encapsulation processes. Whereas the immobilization of
biological molecules is already well-known, the encapsulation of cells still
needs to be extended. The main difficulty lies in the development of matrices
that permit a long term cells viability. In this context, the silica synthesis
<I style="mso-bidi-font-style: normal">via</I> an aqueous sol-gel pathway has
been shown to be an effective rout for bacteria and diatom encapsulation. More
recent developments indicate that this biocompatible encapsulation can be
extended to other metal oxide matrices conferring on them new host
properties.<o:p></o:p></FONT></SPAN></P><BR> </DIV></FONT></FONT></BODY></HTML>
