Virus-built gold nanobeads could be used to purify water or help cuts the costs associated with building electronics.

The bacteriophage virus known as M13 was wrangled by a team from the University of California, Riverside because of its commonality and ease of gene manipulation. M13 has been edited in the past to bind gold ions, so they exposed the virus to water and chloroform to get it to take on a spheroid shape. When a gold ion solution was added to the mix, the virus began building spiky, hollow gold nanobeads that could be used to as photocatalysts to clean wastewater.

According to Elaine Haberer, senior author of the study. "By understanding and harnessing these capabilities, this extraordinary nanoscale precision can be used to tailor and build highly advanced materials with previously unattainable performance."
