Description
Abolghasem Abbasi Kajani, Ali Pouresmaeili, Masoud Ayatollahi Mehrgardi and colleagues cooked up carbon dots that both glow and respond to magnets in 2024. Starting from glucose in a one-pot water-based method, they tuned the recipe with nitrogen sources and metal salts.
A version doped with manganese, sulfur and nitrogen shone in three colours with high quantum yield and stayed stable in suspension. Cells took the dots up quickly with little toxicity, giving sharp fluorescence pictures. The dots also relaxed MRI signals strongly, and the team used them for combined magnetic resonance and fluorescence imaging of tumours in mice. One particle serving two imaging modes could simplify diagnosis.
