Creating new drugs is tough and expensive. Right now, scientists use flat cells or animals to test drugs, but these methods don't always work well for humans. That's where new tech comes in: tiny, 3D versions of human organs, called organoids, and special chips that mimic how organs work. These tools could make drug testing better, safer, and faster.

Organoids are like mini-organs grown in a lab. They can be made from stem cells, which can turn into any type of cell. This means scientists can grow tiny livers, intestines, or kidneys to study how drugs affect them. These 3D structures are much more like real organs than flat cells, so they give better results.

Another cool tool is the "organ-on-a-chip. " This is a tiny chip with tiny channels that mimic how blood flows through an organ. Scientists can put cells on the chip and watch how they react to drugs. This can show how drugs move through the body and where they might cause problems.

These new tools could help scientists test drugs in a way that's closer to how they work in real people. This could mean fewer bad reactions and better drugs. But there are still challenges. Scientists need to figure out how to make these tools work the same way every time and how to analyze all the data they give.

In the future, these tools could even be used to make personalized medicine. This means doctors could grow organoids from a patient's own cells to test drugs before giving them to the patient. This could help find the best treatment for each person.
