DNA-Inspired Strand-Exchange for Switchable PMMA-Based Supramolecular Morphologies

Autor: David J. Lunn, Abigail S. Knight, Youli Li, Bas G. P. van Ravensteijn, Greg G. Qiao, Raghida Bou Zerdan, Craig J. Hawker, Phillip Kohl, Allison Abdilla, Jing M. Ren

Publikováno v: Journal of the American Chemical Society. 141:2630-2635

Inspired by nanotechnologies based on DNA strand displacement, herein we demonstrate that synthetic helical strand exchange can be achieved through tuning of poly(methyl methacrylate) (PMMA) triple-helix stereocomplexes. To evaluate the utility and r

Publikováno v: Journal of Polymer Science Part A: Polymer Chemistry. 56:1259-1268

From readily available starting materials, we report a facile synthesis of lipid–polymer conjugates (LPCs). Easy access to multigram quantities of a dialkyl lipid chain transfer agent allows a range of LPCs to be prepared bearing well-defined hydro

Publikováno v: Bayesian Anal. 14, no. 1 (2019), 81-109

Analysing multiple evidence sources is often feasible only via a modular approach, with separate submodels specified for smaller components of the available evidence. Here we introduce a generic framework that enables fully Bayesian analysis in this
