| Research Abstract |
We have developed the following stimulation-responsive colloidal crystal systems using the specific functions of azobenzene moieties. One is azobenzen-modified silica microparticles dispersed in the nematic liquid crystal. The structure of the particles was observed to change with the photo-irradiation because of the photoisomerization of azobenzene. The other is a gel consisting of (i) astral-shaped actin filaments with their plus end connected on azobenzen-containing polymer beads and (ii) bipolar myosin filaments as linkers. The gel was observed to shrink with the addition of adenosine triphosphate, which mimics the muscle contraction.
