To study the structure and dynamics of biological macromolecules using single molecule fluorescence. Specific biological systems of interest include molecular motors (conventional and unconventional myosins, kinesins, dyneins), receptors involved in neuronal transmissions (voltage-controlled potassium ion channels; ligand-gated ion channels; mechanosensitive-channels), and more recently, genomics. The lab is split between technology development and biological applications. Technique development includes development of single molecule fluorescence, particularly Fluorescence Imaging with One Nanometer Accuracy (FIONA) and related techniques. These are able to get 1 nm accuracy in >2 msec, and 8 nm resolution. Both one- and two-photon excitation is used, where the latter we can get nanometer accuracy and resolution in all three dimensions. Other optical techniques are DOPI (Defocused Orientation and Position Imaging of myosin V), SHREC (Single molecule High REsolution with Colocalization, also known as 2D-FIONA), SHRIMP (Super High Resolution IMaging with Photobleaching), and single-molecule fluorescence resonance energy transfer. Another project is performing single molecule measurements with an optical trap in a cell (as opposed to regular in vitro measurements).
While we do basic research, the hope is that one day this will have real impact. So far, we have a number of patents that have been commercialized: 3 patents on lanthanide-chelates, which are used in high-throughput screening of drugs; 2 patents on single-molecule fluorescence for detecting genetic changes; 1 for detecting super-high-resolution with a few (as opposed to one) dyes; 1 for obtaining a super-stable microscope stage.
- 1.5 nm spatial localization of single fluorescent molecules with 1-500 msec temporal resolution via Fluorescence Imaging with One Nanometer Accuracy (FIONA).
- Determination of hand-over-hand vs. inchworm model for single-molecule myosin V [Yildiz, Science,2003], myosin VI [Yildiz, J. Bio. Chem., 2004; Park, Mol. Cell, 2006], and kinesin [Yildiz, Science, 2004].
- Determination of step-size and rate of stepping of kinesin, dynein in vivo [Kural, Science, 2005].
- < 8 nm spatial resolution between two identical fluorescent dyes [Gordon, PNAS, 2004].

- Development of Lanthanide Resonance Energy Transfer (LRET). This included a 100-fold improvement in signal to background over conventional fluorescence resonance energy transfer [Selvin, PNAS, 1994; Selvin, JACS, 1994].
- First detection of atomic-scale conformational changes in a voltage-controlled ion channel, using LRET [Cha, Nature, 1999].

- Developed new luminescent lanthanide chelates that are alternatives to fluorescent dyes and are particularly useful for discriminating against background fluorescence. This includes their synthesis [Li, JACS, 1995], polarization [Reifenberger, J. Phys. Chem., 2003], and atomic (x-ray) structure [Purdy, Acta Cryst. 2002; Selvin, Inorganic Chem., 1996].
