UN-FUNCTIONALIZED CARBON NANOPARTICLES HAVING FLUORESCENCE CHARACTERISTICS, METHOD OF PREPARATION THEREOF, AND THEIR USE AS BIOIMAGING AND SOLVENT SENSING AGENTS

摘要

The invention relates to non-functionalized carbon nanoparticles having fluorescence characteristics, which are capable of causing bioimaging of cells and sensing of organic solvents. In one embodiment, it relates to method of manufacturing the non-functionalized fluorescent carbon nanoparticles comprising steps of a) depositing carbon soot emanating from flame of a burner on copper surface till at least a layer of carbon soot is deposited on copper surface, and b) removing the layer of carbon soot from copper surface to generate non-functionalized carbon nanoparticles having fluorescence characteristics, which can be directly used as bioimaging agent or solvent sensing agent.
