Automated system detects early signs of nanomaterials toxicity

Korea Research Institute of Standards and Science has developed a toxicity assessment system that automatically measures and analyzes the heart rate of Daphnia magna.

Capable of processing heart rate data from approximately 150 individuals per hour, the system can assess the toxic effects of pollutants at low concentrations more sensitively than conventional methods that rely on average values from a small number of specimens.

The technology is expected to help detect early warning signs of hazardous nanomaterials and environmental pollutants before more visible effects appear. ...
