Two-Dimensional Arrangement and Area-Selective

It was concluded that the photoimmobilization capabihty is not only controlled by photodeformation but also by the retention capabihty, depending on the chemical structure after photoirradiation. Changes in the adsorption properties after the photoimmobilization process are an interesting phenomenon in terms of dynamic changes in the surface properties for adsorption. 

TWO-DIMENSIONAL ARRANGEMENT AND AREA-SELECTIVE IMMOBILIZATION OF MICROSPHERES 

This section proposes a novel and simple method of solving these problems using two photoinduced phenomena of azobenzene-containing polymers. One is a well-known photodeformation process, which provides an intended template for 

Second, the implementation of designed arrays of 2-D colloidal crystals immobilized on a polymer was demonstrated. Two sets of gratings were formed 

To conclude, the authors have succeeded in forming 2-D photonic crystal slabs that include deliberately introduced defects or waveguides. This was accomplished by a newly proposed method comprising two processes, the arrangement and the area-selective immobilization of microspheres. These processes were made possible by utilizing two different photoresponsive properties of azobenzene-containing polymers namely, photodeformation and photoimmobilization.
