Patent number: 9821294Abstract: A self-assembling structure using non-equilibrium driving forces leading to “living crystals” and other maniputable particles with a complex dynamics. The dynamic self-assembly assembly results from a competition between self-propulsion of particles and an attractive interaction between the particles. As a result of non-equilibrium driving forces, the crystals form, grow, collide, anneal, repair themselves and spontaneously self-destruct, thereby enabling reconfiguration and assembly to achieve a desired property.Type: GrantFiled: January 8, 2014Date of Patent: November 21, 2017Assignee: NEW YORK UNIVERSITYInventors: Jeremie Palacci, Stefano Sacanna, David J. Pine, Paul Michael Chaikin

Patent number: 9486768Abstract: A method for creating the colloidal analogs of atoms with valence: colloidal particles with chemically distinct surface patches that imitate hybridized atomic orbitals, including sp, sp2, sp3, sp3 d, sp3 d2 and sp3 d3. Functionalized with DNA with single-stranded sticky ends, patches on different particles can form highly directional bonds through programmable, specific and reversible DNA hybridization. These features allow the particles to self-assemble into ‘colloidal molecules’ with triangular, tetrahedral and other bonding symmetries, and should also give access to a rich variety of new microstructured colloidal materials.Type: GrantFiled: October 28, 2013Date of Patent: November 8, 2016Assignee: New York UniversityInventors: David J. Pine, Yufeng Wang, Yu Wang, Marcus Weck

Publication number: 20160318971Abstract: DNA-coated colloids are introduced that can rearrange and anneal using single-stranded DNA coatings with thicknesses that are smaller than the colloidal particles, and with areal densities 5—than previously achieved. Micrometer-sized colloidal particles, such as poly(styrene), poly(methylmethacrylate) (PMMA), silica and titania, and 3-(trimethoxysilyl)propyl methacrylate (TPM), are coated with DNA by strain-promoted alkyne-azide cycloaddition. This enables growth of large colloidal crystals from a wide range of micrometer-sized DNA-coated colloids. When quenched from above to below the melting temperature, the rate of crystal formation exhibits the familiar maximum for intermediate temperature quenches observed in metallic alloys, but over a temperature range smaller by two orders of magnitude, owing to the highly temperature-sensitive diffusion between aggregated DNA-coated colloids.Type: ApplicationFiled: May 2, 2016Publication date: November 3, 2016Applicant: New York UniversityInventors: David J.

Patent number: 9302240Abstract: A method and system for assembling building blocks of colloidal particles and also for shaping of colloids for self-assembly for manufacturing, processing and formation of compositions of matter. A first type of particle is selected as a “key” particle constructed to mate with a “lock” particle, the binding arising from depletion forces. A variety of shapes can be used to carry out this method and system to create compositions of matter. Colloids can be shaped by controlled deformation of multiphase colloid particles.Type: GrantFiled: August 4, 2014Date of Patent: April 5, 2016Assignee: New York UniversityInventors: David J. Pine, Paul Michael Chaikin, Stefano Sacanna, William Irvine

Publication number: 20150290611Abstract: A method and articles of manufacture for creating colloidal clusters and functionalized patchy particles. The method includes selecting at least one type of colloidal particle, functionalizing a patch of the colloidal particle and mixing a plurality of the colloidal particles to construct a cluster with particular desired geometries properties based on the bonding of the colloidal particles by virtue of the patch having bond-type characteristic analogous to, but not limited to atomic orbitals and other symmetries.Type: ApplicationFiled: October 28, 2013Publication date: October 15, 2015Applicant: New York UniversityInventors: David J.

Patent number: 6872675Abstract: Macroporous ceramics were produced using the droplets of an emulsion as the templates around which the ceramic is deposited through a sol-gel process. Subsequent aging, drying and calcination yields a ceramic with pores in the range of 0.1 to several micrometers which have been left behind by the droplets. The unique deformability of the droplets prevents cracking and pulverization during processing and allows one to obtain porosities in excess of 74%. By starting with a monodisperse emulsion (produced through a repeated fractionation procedure) pores with a uniform and controllable size have been obtained. Self-assembly of these droplets into a colloidal crystal leads to ceramics which contain ordered arrays of pores. A wide range of porosities is obtainable with the advantages of low-temperature sol-gel processing, with a high degree of control and low cost.Type: GrantFiled: February 26, 2001Date of Patent: March 29, 2005Assignee: The Regents of the University of CaliforniaInventors: Arnout Imhof, David J. Pine, Fred F. Lange
