Researchers have successfully synthesized quantum dots (QDs) inside living cells, opening up new possibilities for inorganic molecule synthesis and cellular imaging. Quantum dots are nanocrystals with unique optical properties, including tunable fluorescence and high photostability, making them valuable tools for various applications, such as bioimaging, biosensing, and medical diagnostics.
To overcome the challenge of QD synthesis typically involving harsh conditions and organic solvents, researchers have developed a method to synthesize QDs within specific areas of the cell, such as the nucleus, by using coordinating solvents that stabilize the bulk semiconductors and prevent aggregation during growth. This approach allows for the production of QDs with uniform size and optical properties, which is crucial for their functionality.
