New metal-free molecules glow deep red in water and boost MRI contrast in test images
Bioimaging technologies, such as fluorescence imaging (FI) and magnetic resonance imaging (MRI), are powerful tools in basic research and clinical medicine. But they have drawbacks.
AI Summary
Bioimaging technologies such as fluorescence imaging and magnetic resonance imaging have limitations: fluorescence imaging offers high resolution but lacks imaging depth, while MRI can image deep within the body but does not provide single‑cell resolution. Additionally, MRI contrast agents contain paramagnetic metals like gadolinium, which can potentially cause adverse side effects.
