    • The present invention relates to highly ordered arrays of colloidal 2D crystals on a substrate and to an improved method for producing the same. The method according to the invention for producing an highly ordered array of colloidal 2D crystals on a substrate comprises the following steps: a) providing a suspension of microspheres comprising poly-N-isopropylamide (polyNIPAM), the microspheres being selected from pure poly-N-isopropylamide (polyNIPAM) hydrogel microspheres, functionalized polyNIPAM microspheres, and polymeric or inorganic beads carrying poly-N-isopropyl-amide (polyNIPAM) hydrogel chains, in an aqueous medium on a substrate, wherein the aqueous medium comprises a mixture of water and a lower alkyl alcohol, b) subjecting the suspension deposited on the substrate after step a) to a shear force, and c) drying the suspension. In a preferred embodiment of the invention, the shear force is generated by applying a pulsed gas stream to the substrate surface. The colloidal 2D crystal arrays obtained by this method have an exceptional high long range order, including monocrystalline domains in the range of square millimetres.

    • The present disclosure is directed generally to devices and methods with the purpose of interfacing micro fluidic devices with dispensing and fluid handling systems to achieve the rapid identification of protein crystallization conditions. The device described herein is fabricated with the use of a cyclic olefin homopolymer-based creating microfluidics system adaptable for protein crystallization and in situ X-ray diffraction. Connectivity between chambers is controlled by valves that allow specified volumes of liquid to be transferred from one chamber to another. The microfluidic system is useful to established microbatch, vapor diffusion and free interface diffusion protocols for protein crystallization and to obtain crystals for a number of proteins, including chicken lysozyme, bovine trypsin, a human p53 protein containing both the DNA binding and oligomerization domains bound to DNA and a functionally important domain of Arabidopsis Morpheus' Molecule 1 (MOMl). For X-ray diffraction analysis, either the microfluidic devices were opened to allow mounting of the crystals on loops or the crystals were exposed to X-rays in situ. Thus, cyclic olefin homopolymer-based microfluidics systems are useful to further automate protein crystallization and structural genomics efforts.
