Researchers at the University of Edinburgh created a 3D-printed "body-on-chip" device containing miniature replicas of human organs.
This device mimics how drugs flow through the body, allowing scientists to test their effects on different organs without using animals.
Five tiny compartments represent the heart, lungs, kidney, liver, and brain, connected by channels like the circulatory system.
PET scanning technology reveals detailed 3D images of drug activity within the organs, helping scientists understand its distribution and duration.
The device is flexible and can be adapted to study various diseases, including cancer, cardiovascular issues, and neurodegenerative disorders.
This "body-on-chip" technology has the potential to reduce animal testing in drug development, accelerate clinical trials, and improve understanding of human diseases.
