For the first time, it is proved that "nano silver" can also produce drug resistance!

A new study by the University of Technology Sydney (UTS) found that pathogens that form biofilms can evolve to survive nano-silver treatment

This research was published in the famous "Journal of Nanobiotechnology"

Nano silver is an effective antibacterial agent, currently used in medical equipment, such as internal catheters, and wound dressings, especially burn wounds, to fight or prevent infection

Researchers at the UTS iThree Institute studied the nanosilver adaptation phenomenon in the growth of Pseudomonas aeruginosa biofilms and observed a new adaptation mechanism that has not been seen in previous studies on plankton growth

"Understanding how pathogens develop adaptation mechanisms to nanoparticles is the key to our efforts to overcome this phenomenon, including biofilms as the main form of growth of pathogenic bacteria

The lead author of the study, Dr.

"Based on this research, we recommend monitoring patients not only during long-term treatment with nanoparticles, but also after long-term treatment with nanoparticles to prevent recurring infections

"There is scientific evidence that bacteria can adapt to nanoparticles, which means that we need to effectively monitor the use of nanoparticles, conduct clear risk and benefit assessments, and clarify antibacterial targets

The bacteria used in the study is Pseudomonas aeruginosa, which usually attaches to the surface of catheters, wounds and the inner wall of the lungs, forming a biofilm that is difficult to control
