A new type of electronic paper was announced by scientists at the ACS meeting held March 28 to April 1, in Anaheim, Calif.
The paper consists of bacterial cellulose with an electronic dye between transparent electrodes.
To make the paper, professor of molecular genetics and microbiology R. Malcolm Brown Jr., and graduate student Jay Shah at the University of Texas, Austin, start with a sheet of pure cellulose, which is one of the main structural components of wood and reflects and bends like conventional paper. This cellulose, however, is made not by plants but by Acetobacter xylinum bacteria. The bacterial cellulose is more structurally uniform and hardy than wood cellulose and can be grown in any shape.
