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.

By late 2017, the first patent was filed, the material proven to kill bacteria including numerous resistant bacteria

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.

Pre-clinical research on new antimicrobial spray and coating technology published

January 26, 2023

Amferia announced today that it has, in collaboration with Chalmers University of Technology, published two important scientific articles in peer-reviewed journals that describe the pre-clinical studies of its platform technology, Amphiphilic Antimicrobial Hydrogel as sprays and coatings for various medical device applications.

Amferia’s platform technology is an amphiphilic antimicrobial hydrogel material that can rapidly bind and kill all types of bacteria, even resistant bacteria, without harming the body. In an effort to enable further applications of this material, Amferia collaborated with Chalmers University of Technology to test and develop the patented technology as sprayable formulation and as coatings fight off bacterial infections in medical devices.

Today, the extensive pre-clinical data from this research has been published in two scientific articles in peer-reviewed journals*. The research was built on the formulation of the Amphiphlic Antimicrobial Hydrogel as small discrete particles, which were then further developed as sprayable form for wound care and as a coating on existing materials like silicone catheters. The results from these studies show powerful antimicrobial effect, safety to human cells while being stable in biological environments such as serum.

The material has been shown to be effective against many different types of bacteria, including those that are resistant to antibiotics

Martin Andersson, Professor at Chalmers University and Co-founder of Amferia − “Our innovation can have a dual impact in the fight against antibiotic resistance. The material has been shown to be effective against many different types of bacteria, including those that are resistant to antibiotics, such as Methicillin-resistant Staphylococcus aureus (MRSA), while also having the potential to prevent infections and thus reduce the need for antibiotics,.”

The research was undertaken based on the strong potential of Amferia’s technology, but also based on a clear need from the human and animal health care system on fighting infections in the context of deep infected wounds as well as for various medical devices such as urinary catheters. Amferia and Chalmers will continue to collaborate on this research and are planning to further study the use of the new formulations in clinical settings, both for human and animal care.

We are seeing the great potential of our technology going beyond wound care into the realm of broader medical devices

Anand Rajasekharan,CEO of Amferia − “This is an important achievement for Amferia as we are seeing the great potential of our technology going beyond wound care into the realm of broader medical devices such as coatings and sprayable systems. Our current product is a wound dressing and we look forward to follow-up the same with these pipeline products that will have a stronger impact for addressing antibiotic resistance.”

*The scientific article on the formation of antimicrobial hydrogel particles as sprays and its in-vitro efficacy, safety and stability is published in Cross-linked lyotropic liquid crystal particles functionalized with antimicrobial peptides, Blomstrand et. al. 2022

*The scientific article on the utilisation of these particles as coatings on silicone materials is published in MultifunctionalSurface Modification of PDMS for Antibacterial Contact Killing andDrug-Delivery of Polar, Nonpolar, and Amphiphilic Drugs, Stepulane et. al. 2022
