New Metal-Free Molecules Can Help Medical Imaging

Topic: Biology

Scientists from Kyushu University developed two new molecules that can glow deep red in water and help improve medical imaging. These molecules are metal-free and can be used with both fluorescence imaging and magnetic resonance imaging (MRI).

Bioimaging technologies like fluorescence imaging (FI) and magnetic resonance imaging (MRI) are very useful for research and medicine, but they have some limitations. FI can show cells and biological processes clearly, but it can't see deep inside the body. MRI can see deep inside the body, but it can't show single cells clearly. Also, MRI contrast agents contain metals that can be harmful to our bodies.

A team of scientists from Kyushu University wanted to create a new molecule that could help with both FI and MRI. They worked on a type of molecule called luminescent organic radicals, which can glow and help with MRI. However, these molecules were not very useful because they didn't mix well with water.

The team led by associate professor Ken Albrecht created two new molecules: TTM-trisTP3B and TTM-trisTP9B. These molecules are bound to water-soluble groups and can glow deep red in water. They tested these molecules in living cells and found that they could help with MRI imaging. The molecules also made the images clearer than before, which is a big improvement.

The scientists are excited about their discovery because it could lead to better medical imaging techniques. They plan to test these molecules further in animal studies to see if they are safe for use in humans.
