+++++++++++++++++++++++++
pSivida Limited (ASX:PSD) is pleased to announce that Professor
Jeffrey Coffer of the Chemistry Department at Texas Christian
University, Fort Worth, Texas (TCU), has recently been appointed as a
collaborator with pSiMedica, our UK based operating subsidiary.

Professor Coffer has a wealth of research experience in semiconductor
nanocrystal synthesis, properties and characterization, with
particular reference to porous silicon (BioSilicon(TM) when used in
or on the human body). Professor Coffer has lead cutting edge
research in the US on the chemical properties of porous silicon since
1992.

In recent years, he and his team at TCU have been focusing on
research in BioSilicon(TM) in the fields of orthopaedics and tissue
engineering collaborating informally with pSiMedica, as well as
researching silicon nanowires and rare earth incorporation into
porous silicon for optoelectrical and biomedical applications.

Gavin Rezos, Managing Director of pSivida, said "Our increased
presence in the US is being recognized with top US researchers in the
nano-silicon area joining with us. It is expected that our
subsidiary, pSiMedica, will now move to a more formal relationship
with Texas Christian University, in relation to the work being done
by Professor Coffer, in conjunction with our own Professor Leigh
Canham."

In addition, pSiMedica's Professor Canham recently gave the invited
keynote Drug Delivery and Therapeutics session speech at the US
Materials Research Society Spring 2003 Conference in San Diego,
recognizing his role in BioSilicon(TM).

pSiMedica owns all intellectual property rights royalty free in
relation to BioSilicon(TM) for which there are six granted patents,
16 patent families with four more in development and over 65 patent
applications.
