Innovation in Biological Separation Processes

Memphasys specialises in biological separations for commercial applications.   

Memphasys’ patented membrane processes enable the selection of high value substances or contaminants from the fluid in which they are contained by applying an electrical field (electrophoresis) to a sample of the fluid that is contained between our membranes.  Proteins or cells can be extracted utilising Memphasys’ proprietary polymer separation membranes to pick out specific components based on their size and relative charge.

Sperm Separation Technology

Memphasys’ sperm separation technology selects the most viable sperm from semen samples for use in fertility treatments including IVF for humans, and potentially in various Assisted Reproductive Technologies (ART) for animals.

There is a higher incidence of miscarriage, premature births and various genetically-based diseases such as cancers and neurological diseases in progeny created using IVF and certain other ART fertilization methods than there is from natural fertilisation. 

There is increasing concern that current human sperm preparation techniques for extracting the sperm from semen sample may be contributing to these results, as they can physically damage the sperm, and lead to oxidative stresses and DNA damage.  

The Company's technology has been developed in partnership with Professor John Aitken from the University of Newcastle, Australia – a world-leader in human fertility research.  Under Prof Aitken’s leadership, extensive proof of concept testing of the research device has been completed, which has resulted in publications endorsing the quality of the sperm selected using the sperm separation technology.

Memphasys is now developing a next-generation of sperm separation technology, the 'Felix' products, for clinical use in human IVF centres worldwide.

Membranes Separation

Over the past 15 years Memphasys has developed a polymer membrane separation technology using polyacrylamide hydrogel membranes with electrophoresis.

Memphasys’ current range of research lab instruments were developed to allow this separation technology to be used in the research sector to assess new applications.

Memphasys is now well advanced in developing and validating an improved membrane material that is biologically-compatible and easily scalable in ambient conditions.

Intellectual Property

Memphasys has patents relating to electrophoresis apparatuses, consumables (e.g. separation cartridges and separation membranes) and other hardware for biological separation

Memphasys also holds patents specific to the sperm separation technology and an exclusive license agreement with our clinical research partner, the University of Newcastle, for IP they have developed in sperm separation.

The new separation membrane material currently being developed will generate new application and method patents in the coming years.
