Summary

Story summary

Canadian researchers have developed a three-dimensional heart-on-a-chip that beats autonomously and responds predictably to drugs.
The device enables real-time monitoring of both large-scale contractions and cellular activity.
It integrates dual-sensing technology to assess how heart muscle cells react to norepinephrine and blebbistatin.
Future work aims to create patient-specific heart tissues for personalized medication testing and precision health.
