Using nanostructures to fight bacteria - 09/10/2025

Inspired by insect wings: antibacterial surfaces for implants

What do dragonfly wings and dental implants have in common? Nothing yet but that could soon change. The Karlsruhe-based start-up nanoshape has developed a process for coating medical implants with nanostructures similar to those found on insect wings. The coating makes surfaces bacteria-repellent and is aimed at reducing the risk of post-surgical inflammation. The first product could be on the market as early as next year.

A researcher team from Ecole Polytechnique Federal de Lausanne led by Dr. Vivek Thacker now group leader at the Department of Infectious Diseases at Heidelberg University Hospital have studied why tuberculosis bacteria form long strands and how this affects their infectivity. Their findings could lead to new therapies and have now been published in the journal Cell.

The hospital pathogen Pseudomonas aeruginosa requires the sugar-binding proteins LecA and LecB to form biofilms as well as to attach to and penetrate host cells. These so-called lectins are therefore suitable targets for active substances to combat Pseudomonas infections. Researchers from Saarbrücken and Freiburg have now produced potent inhibitors for LecA and LecB that are more stable and soluble than previous drug candidates.

Multiresistant pathogens a self-inflicted threat?

Most bacterial infections have lost their capacity to cause terror thanks to antibiotics. However, the increase in antibiotic resistances is making the fight against bacterial pathogens rather difficult, and the widespread overuse and inappropriate use of antibiotics continues to fuel the increase in antibiotic-resistant bacteria.
