In-situ Formation of Hydrogel Membranes and Growth of Colloidal Crystals in Microchannels Using One Step Stamping
نویسندگان
چکیده
This paper reports a novel method for in-situ formation of hydrogel membranes and geometrically controlled selfassembly of colloidal crystals in microchannels using one step stamping. The simple elastomeric stamp was made of PDMS from SU-8 patterned master using standard soft lithography. Then the selective hydrophobic pattern on the PDMS stamp surface was achieved using Pluronic F127 coating and staircase design. Finally, with this PDSM stamp, not only the formation of the In-situ hydrogel membranes with closed loop, but also the growth of colloidal crystals within microchannels was carried out.

Good model systems are required in order to understand crystal growth processes because, in many cases, precise incorporation processes of atoms or molecules cannot be visualized easily at the atomic or molecular level. Using a transmission-type optical microscope, we have successfully observed in situ adsorption, desorption, surface diffusion, lattice defect formation, and kink incorporation o...
