Abstract

A microfluidic approach for the complex formation of polyelectrolyte and polyelectrolyte/protein microstrips on a glass surface is discussed. A new, soft micropatterning technique for the anisotropic modification of micrometer-sized objects such as spherical microparticles and polyelectrolyte capsules is also demonstrated. Synthesis of poly(dimethyldiallylammonium chloride)/poly(styrene sulfonate) (PDDA/PSS) microstrips is also demonstrated. It is found that the width of the microstrips, as well as their position in the microchannel can be controlled by varying the flow rate and concentration of the individual components.
