The New York University MRSEC for Semantophoretic Assemblies (semantophoretic = carrying information) unites established senior and promising junior faculty from four NYU Departments, Princeton University, NYU Polytechnic Institute, Text Box: Figure C.4.1. Schematic representation of polymerase-catalyzed generation of DNA scaffolds with pendant monomers from nucleoside-monomer substrates (B = nucleotide; two monomers here depicted as blue and green pendant groups). The knot structure, enforced by the oligonucleotide sequence, contains a sequence-specific ordering of the monomers along the scaffold. Polymerization of the monomers attached to the knotted scaffold by a second enzyme, followed by cleavage from the scaffold, produce a copolymer with a knot topology and a sequence encoded by the oligonucleotide sequence. and collaborators from key institutions, in an interdisciplinary program that addresses the synthesis, structure, and properties of innovative materials based on constituents equipped with self-contained information that directs assembly, either through shape or chemical interactions. The NYU MRSEC reinforces a rapidly growing interdisciplinary materials research enterprise at NYU, embodied by collaborations among the Departments of Chemistry and Physics, the Courant Institute of Mathematics, and the Biomimetics and Biomaterials program in the NYU Dental School.

The NYU MRSEC enjoys substantial synergy in two large NYU initiatives – the Molecular Design Institute (MDI) in Chemistry and the Center for Soft Matter Research (CSMR) in Physics – that collectively support materials research spanning length scales ranging from the molecular to the macroscopic. The MRSEC also supports a robust Education and Human Resources program that spans the entire range of academia, with the aim of enhancing science curricula and awareness at the K-12 level, providing unique research experiences for undergraduates and faculty from four-year institutions, and endowing graduate students with skills for communicating science to the public. As such, the NYU MRSEC establishes a unique venture in the New York City region.

 

Highlights

Text Box: Figure C.4.1. Schematic representation of polymerase-catalyzed generation of DNA scaffolds with pendant monomers from nucleoside-monomer substrates (B = nucleotide; two monomers here depicted as blue and green pendant groups). The knot structure, enforced by the oligonucleotide sequence, contains a sequence-specific ordering of the monomers along the scaffold. Polymerization of the monomers attached to the knotted scaffold by a second enzyme, followed by cleavage from the scaffold, produce a copolymer with a knot topology and a sequence encoded by the oligonucleotide sequence. Recently Daniel Saltiel, from the 2008 NYU CCNY SESMI REU Program, working in Professor Paul Chaikin's laboratory, looked at the effeiciency of self-organizing colloids utilizing hydrodynamic reversibility in elongation flow. As this figure demonstrates, it began as a circle, but was stretched out by flow in from the top and the bottom, then out from both sides. When the flow directions are reversed, the circle will reform, then distort the other way. Particles then placed in the center can efficiently self-organize.
