From November 7–9, 2025, the International Warsaw Invention Show (IWIS) was held at the Copernicus Science Centre – the largest event in Poland promoting inventiveness and innovation. The exhibition provides an opportunity to present scientific achievements on an international stage and to establish contacts with business partners and investors.

We are pleased to announce that the Silver Medal at IWIS 2025 was awarded to a solution developed at the Institute of Chemical Technology and Engineering, Faculty of Chemical Technology, Poznań University of Technology, entitled:

“Method of producing polyester material for artificial tendon.”

The authors of the award-winning invention are: Prof. Adam Voelkel, PhD, DSc, Eng.; Dr. Mariusz Sandomierski, DSc, Eng.; and Jakub Reczkowski, MSc, Eng.

The invention concerns an innovative method for producing a polyester material intended for implant applications, particularly as an artificial tendon. The material is modified with a polyurethane layer and enriched with ciprofloxacin, giving it antibacterial properties and high biocompatibility. The developed technology includes depositing a bioactive coating and targeted antibiotic impregnation. The synergy of these solutions allows the creation of a smart material that:

• Increases patient safety,
• Reduces the risk of infection at the implantation site,
• Supports the healing process.

The invention may help shorten recovery time, reduce the risk of postoperative complications, and lower the costs of treating infectious complications. The material can be applied in areas such as tendon reconstruction after mechanical injuries, sports orthopaedics, and implantology.
