Light: Science & Applications paper
Our work on combining microtoroid optical resonators with photothermal microscopy to detect single 5 nm quantum dots with a signal-to-noise ratio > 10^4 without the use of labels has been published in Light: Science & Applications. We thank an NIGMS R35 grant and the Gordon & Betty Moore foundation for support. We anticipate our work will have applications in a variety of fields including the biological sciences, nanotechnology, materials science, chemistry, and medicine.
