Abstract
A glass pipette such as an electrode for electrophysiological recording is coated with quantum dots. This greatly aids the ability to observe the glass pipette, particular in tissue as the quantum dots provide an excellent performance under two-photon illumination used to visualize objects at depths of hundreds of microns.
Claims17
A device comprising:
- a glass pipette coated with a plurality of quantum dots.
A method of coating a glass pipette with quantum dots, the method comprising:
- providing quantum dots suspended in an organic solvent, and
- contacting a glass pipette with the quantum dots suspended in an organic solvent, thereby causing the quantum dots to coat the glass pipette.
A kit comprising:
- quantum dots and an organic solvent suitable for suspending the quantum dots for coating on a glass pipette, and
- printed instructions for using the quantum dots suspended in an organic solvent to coat a glass pipette.
