Australian biotech Memphasys Limited (ASX: MEM) has recently made headlines by securing provisional patent approval for its innovative RoXsta™ System, a next-generation platform designed to measure oxidative stress—a factor linked to cellular damage and several health conditions. Paired with a recent capital injection of $1.857 million from a Placement and Share Purchase Plan, Memphasys appears poised for a new growth phase.
The RoXsta™ System tackles a persistent problem across various health and research fields: the need for rapid, reliable measurements of oxidative stress. Elevated oxidative stress is associated with cellular damage, reproductive issues, degenerative diseases, and even impaired physical performance. RoXsta™ provides results in roughly five minutes, making it suitable for point-of-care assessments across a variety of settings, from fertility clinics to equine and cattle breeding facilities.

RoXsta™ recently received a significant endorsement from the International Search Report (ISR), which confirmed all claims in its patent application as novel and inventive. The provisional patent publication is expected in June 2025. For Memphasys, this milestone solidifies its standing in the competitive oxidative stress diagnostics market. According to Memphasys’ Scientific Director, Laureate Professor John Aitken, the speed and versatility of RoXsta™ offer "real-time insights into oxidative imbalances," which could benefit infertility treatment, animal health, and performance monitoring.
Adding to the system's credentials, Memphasys also announced that a research paper detailing RoXsta™’s technical development has been accepted for publication in Antioxidants, a well-regarded international journal. The article delves into the system’s unique capabilities and outlines how RoXsta™ delivers fast, adaptable oxidative stress measurements across multiple sample types, including blood, saliva, and plant extracts.
Memphasys is actively working with industry stakeholders to fine-tune RoXsta™ for commercial applications, with studies underway in the thoroughbred horse racing sector to assess how oxidative stress impacts reproductive health. Further research aims to explore its potential in human fertility, given that oxidative stress levels are increasingly recognised as a factor in male infertility—a condition affecting about 10% of men of reproductive age.
A partnership with the University of Newcastle is set to push RoXsta™’s capabilities further. Initial scoping work will focus on measuring oxidative stress in cattle, a venture that could eventually lead to a broader clinical trial. These efforts underscore Memphasys’ intention to make RoXsta™ an essential tool across human and animal health domains, from infertility to performance management in breeding and sport.
The timing of the $1.857 million capital raise couldn’t be better. By securing these funds through a Placement and Share Purchase Plan, Memphasys gains the resources to push ahead with RoXsta™’s commercialisation and research objectives. In biotech, where regulatory hurdles and technical demands are high, such funding is crucial to sustaining momentum.
This latest development positions Memphasys as a company with both the scientific credibility and financial support to advance its technology towards commercial impact. If RoXsta™ can prove its mettle in real-world applications, Memphasys may well establish itself as a leader in the evolving field of oxidative stress diagnostics.
With its fresh capital and strategic research initiatives, Memphasys offers investors an intriguing proposition: a cutting-edge product, growing industry collaborations, and the kind of scientific backing that sets the stage for potential long-term success.
