Queensland government-supported plasma biotech Aegros is attempting to raise $20 million from investors ahead of a 2025 float, despite one of its suppliers being forced to lodge a winding up action in the Supreme Court of Victoria to secure payment.

The business, co-founded by haematologist Hari Nair and biotech entrepreneur John Manusu in 2017, is attempting to commercialise a blood plasma fractionation technology that has been in development since the 1980s and is designed to provide a major boost to the yield of immunoglobulin from plasma.
