genetically determined design of structured functional bio/inorganic
materials was investigated by applying a convective assembly approach.
Wildtype tobacco mosaic virus (wt TMV) as well as several TMV mutants
were organized on substrates over macroscopic-length scales. Depending
on the virus type, the self-organization behavior showed pronounced
differences in the surface arrangement under the same convective assembly
conditions. Additionally, under varying assembly parameters, the virus
particles generated structures encompassing morphologies emerging
from single micrometer long fibers aligned parallel to the triple-contact
line through disordered but dense films to smooth and uniform monolayers.
Monolayers with diverse packing densities were used as templates to
form TMV/ZnO hybrid materials. The semiconducting properties can be
directly designed and tuned by the variation of the template architecture
which are reflected in the transistor performance.
