Method for the attachment andor crystallization of macromolecules, chemical reagents used in the said method, products obtained as well as applications of the said products in the field of materials and of structural biology, in particular as biosensors or as biomaterials. The horizontal rotary device is mounted on the seat and is capable of rotating freely to adjust the horizontal angle. A pixel matrix circuit and logic circuitry are formed on the active matrix substrate. The designs are printed on a synthetic poly silk fabric using dye sublimation process and may easily be cleaned with a damp sponge or cloth. The system further includes a voltage source to which each ionizer and each attractor is electrically connected.
