Abstract

Single adeno- and tobacco mosaic viruses have been studied by correlated fluorescence spectroscopy and tapping-mode atomic force microscopy. The size and shape of spatially isolated, fluorescently tagged viruses are measured on the nanometer scale, and the fluorescent labels in each virus are determined by wavelength-resolved spectroscopy. This work extends ultrasensitive measurement to the single-virus level and is expected to have applications in studying gene therapy vectors and virus-cell interactions.
