METAL-ENHANCED PHOTOLUMINESCENCE FROM CARBON NANODOTS

摘要

The present invention relates to enhancement of detectable emissions from carbon nanodots or variants thereof by using the techniques of MEF to further enhance carbon nanodot brightness, photostability, and thus, potentially detectability in biological imaging applications by using plasmon supporting materials, such as silver island films and positioning of the carbon nanodots an optimal distance from the plasmon supporting materials.

主权项

1. A method for increasing detectable emissions from excited carbon nanodots, the method comprising:
providing metallic particles, wherein the metallic particles are immobilized on a surface substrate and the metallic particles are nanostructures, islands, or colloids; introducing at least one carbon nanodot or variant thereof for disposing near the metallic particles, wherein the carbon nanodot or variant thereof is capable of emitting a detectable signal upon excitation and positioned from about 5 nm to 200 nm from the metallic particles; applying electromagnetic energy to excite the carbon nanodot or variant thereof; and measuring the emission from the carbon nanodot or variant thereof, wherein proximity to the metallic particles increase emission and detectable signal.
