摘要：
We have developed a wide-field total-internal-reflection fluorescence microscope capable of imaging single molecules in live cells, resolved in both wavelength and polarization. We show fluorescence resonance energy transfer between single pairs of fluorescent molecules bound to signaling receptors in the plasma membrane of live cells and demonstrate the importance of polarization discrimination in addition to wavelength separation.
