Virus-Embedded Hydrogel Kills Bacteria

Virus-Embedded Hydrogel Kills Bacteria
A novel hydrogel made from bacteria-killing viruses could have applications ranging from wound dressings to fighting cancers.

The hydrogel was created by a team from McMaster University using lab-grown bacteriophages. The phages were packed tightly inside a confined space and then treated with a chemical binder, which caused them to self-assemble into a hydrogel. Each millimeter of the hydrogel surface holds about 300 trillion phages that can be modified to attack different targets—including antibiotic-resistant bacteria.
