Research Abstract

The current study developed a single molecule detection system, which allows the simultaneous observation of the position (x, y, z), orientation (theta, phi), and emission wavelength lambda, as a function of time t. This system enables us to completely record the motion of a single fluorescent molecule.
The dynamics of poly(methyl acrylate) films was examined by the single molecule microscopy system developed here. The rotational motion in an ultra thin film with a thickness of 5 nm was suppressed compared to that in a three-dimensional bulk state. The detailed analysis of the molecular rotation revealed that the rotational relaxation time in the out-of-plane direction was 30-times longer than that in a bulk state and that the in-plane rotation in the ultra-thin film was almost the same as that in a bulk system. This indicates that the molecular rotation in an ultra-thin film is restricted only in the thickness direction.
