Organoids serve as a vital tool for scientists, providing a closer representation of human tissues than traditional two-dimensional cell cultures. Their ability to replicate the intricate behaviors of human organs makes them exceptional models for investigating various diseases and testing treatments. However, one of the significant hurdles researchers face with organoids is the challenge of monitoring the internal processes effectively. Existing techniques are often either too costly, destructive to the tissue, or incapable of providing detailed insights into deeper tissue layers. The team at the Technion has successfully devised a method that tackles these limitations, allowing them to observe dynamic changes in organoids without causing damage, all while keeping costs manageable.

The innovation hinges on the analysis of volatile organic compounds (VOCs), which are small molecules emitted from tissues and detected in biological fluids such as breath and sweat.
