A Facial Mask Capable of Detecting COVID-19 via Colorimetric Indication

At a Glance

Researchers at Colorado State University have developed a “smart” face mask incorporated with nanofiber-based biosensors capable of in-situ detection of the novel coronavirus that causes COVID-19, signaling the viral infection via a colorimetric change.

Polydiacetylene (PDA) is an attractive molecule for use in chemosensors, due to its unique characteristic of undergoing a blue-to-red color change in response to targeted stimuli. Recently, PDA synthetic vesicles have demonstrated colorimetric detection of various biological contaminants, including influenza virus and E. coli in saline solutions. Development of “smart” Personal Protective Equipment (PPE) could decrease the spread of the current pandemic, as infected patients can be more readily identified.


  • Easy detection and diagnostic device to identify contamination of the novel coronavirus
  • Can be applicable to other types of PPE
