A New Way to Fight Bacteria?

 
For years, scientists have used antibiotics to fight bacterial infections. Recently, some bacteria has evolved to be resistant to the antibiotics. Scientists have been working to find a way to treat people who have this drug resistant bacteria. Along with some of his colleagues, Vesselin Paunov has experimented with a new way to do this. The method involves producing colloid particles, which are tiny particles spread in a larger material, produced synthetically in the lab. These particles are called colloid antibodies. The antibodies contain a killing agent and have been designed to recognize and attach themselves to a certain kind of bacteria. When the scientists performed tests on this, the colloid antibodies did what they were supposed to and did not harm any other body cells.
 
I think it is really cool that these scientists came up with a creative possible solution to this problem. It would be great if this solution turns out to work and is practical and affordable. I am excitied to see where this goes in the future.
 
NOS Themes:
Role of motivation and curiosity: The scientists were motivated to find a way to kill antibiotic resistant bacteria.
Importance of Repeatability: It is important that this method is tried many times before actually being used as a widespread treatment.
