| Abstract: | Colloidal lithography was used to make a novel array (2-D) of micro-rings, dots, and interconnected-honeycomb structures.
These geometries are controlled using the curing temperature-dependent rheological properties of the siloxane elastomer precursor.
Serratia marcescens was patterned on the interconnected honeycomb microstructure demonstrating a potential application for microbioanalytical
devices, microfluidics, and bio-micro-electromechanical systems.
