Introducing Amferia wound dressing for animal care — binds and kills bacteria without harming the body

How antimicrobial hydrogel can revolutionize clinical treatments

Binds and kills 99.99% of bacteria without harming the body – even resistant bacteria

”After years of research we suddenly realised how to combine our findings. It was a eureka moment.”

The Amferia story:

Amferia was born in Gothenburg, Sweden, when three PhD researchers who had been collaborating for five years had the idea to combine their findings. In 2016, after several conversations among themselves, Amferia founders Saba Atefyekta, Anand Kumar Rajasehkaran and Martin Andersson conceived a new class of antimicrobial material while working at Chalmers University of Technology .

The approach was to utilise antimicrobial peptides—a potent antimicrobial molecule that Saba Atefyekta was investigating for biomaterial applications — in combination with a new amphiphilic hydrogel developed by Anand Rajasekharan for his PhD research on synthetic bone.

Within the first two weeks, we noted that the idea was sound and worked perfectly, which is a rarity in science” 

During a conference visit to Montreal in May 2016, Saba, Anand and Martin dove deeper into discussions and realized their combined research had uncovered potential for real-world biomedical applications. ”After all these years of research we suddenly realised how to combine our findings. It was a eureka moment,” said Saba.

Excited by their discoveries, Saba and Anand returned to the lab and initiated the first trial runs, synthesizing the material and testing it on bacteria. “Within the first two weeks, we noted that the idea was sound and worked perfectly, which is a rarity in science,” said Anand.

From basic research to a high-impact product

The company:

After months of trials and more trials focused on optimizing the commercial viability of the product, the founders knew their idea had life beyond the lab and science publications. They knew they could develop a new, innovative product to target and kill bacteria in medical applications.  

The team immediately reached out to the innovation arm of Chalmers University and filed for a patent. Then they engaged in intense market research, while continuing further experiments on resistant bacteria.

By late 2017, the first patent was filed, the hydrogel had been proven to kill bacteria — including numerous resistant bacteria — and was safely used in biological environments without toxicity. Most importantly, the founders agreed their first product using the new technology should address wound care.

Since then, the company has worked hard and successfully scaled the technology, completed clinical evaluations in both human and animal wound care and are now preparing for their regulatory approvals.  

With further support from Chalmers innovation Office and a seed funding from Chalmers Ventures, Amferia was officially incorporated in September 2018. Both Anand and Saba, completed their PhDs and jumped on board to continue their full-time journey, translating fundamental research into new products for human and animal health.

Today Amferia is a talented team of seven, with dedicated personnel for business development, sales, clinical development, product development and production.

The Recent UN Report on Antibiotic Resistance

May 3, 2019

The United Nations appointed Interagency Coordination Group on Antimicrobial Resistance (IACG) has presented its report on Recommendations to Combat Antimicrobial Resistance (AMR). It is clear from the report that AMR is a global and complex threat that needs to be addressed with extreme urgency and with care. Consistent, coordinated and conscious actions are demanded, especially from the World Goverments, Academia, Public, Healthcare-Industry and  Agriculture. A world where bacterial infections cannot be fought efficiently is a world of perils.

Here is an excerpt from the IACG report.

“The challenges of antimicrobial resistance are complex and multifaceted, but they are not insurmountable. Implementation of the recommendations in this report will help to save millions of lives, preserve antimicrobials for generations to come and secure the future from drug-resistant diseases.

But there is no time to wait.”
