Photophobic and phototropic movement of a self-oscillating gel

Irving Epstein

Brandeis University

A photosensitive self-oscillating gel that incorporates the Belousov-Zhabotinsky reaction can undergo rhythmic mechanical oscillations. Irving Epstein discusses the dependence of the oscillation frequency on light intensity to generate both photophobic and phototropic movement of the gel under differential illumination Read the Study
