The invention relates to methods for measuring conformational changes and self-assemblyaggregation of proteins, especially the formation of amyloid fibrils, using conjugated polyelectrolytes. The shunt member has shunt contacts defined by turned up portions from an edge of the members. The SRAM also writes in a full N bits simultaneously after sequentially latching in NX bit words in X burst cycles into N write drivers. Preferably it is sprayed with a natural latex.
