Journal ArticleDOI
Stimuli-responsive molecular brushes
TL;DR: In this paper, the authors review the general aspects of molecular brushes and polymeric responsive systems and highlight the rational approaches to induce stimuli-responsiveness in molecular brush systems, which are unique for molecular brushes since these conformational changes can be restricted to a single molecule.
Journal ArticleDOI
Biodegradable Nanogels Prepared by Atom Transfer Radical Polymerization as Potential Drug Delivery Carriers: Synthesis, Biodegradation, in Vitro Release, and Bioconjugation
Jung Kwon Oh,Daniel J. Siegwart,Hyung-il Lee,Gizelle A. Sherwood,Linda A. Peteanu,Jeffrey O. Hollinger,Kazunori Kataoka,Krzysztof Matyjaszewski +7 more
TL;DR: Results obtained from optical fluorescence microscope images and live/dead cytotoxicity assays of HeLa cancer cells suggested that the released Dox molecules penetrated cell membranes and therefore could suppress the growth of cancer cells.
Journal ArticleDOI
Light‐Induced Reversible Formation of Polymeric Micelles
Hyung-il Lee,Wei Wu,Jung Kwon Oh,Laura Mueller,Gizelle A. Sherwood,Linda A. Peteanu,Tomasz Kowalewski,Krzysztof Matyjaszewski +7 more
TL;DR: Polymeric micelles can be completely disrupted by UV irradiation and reversibly regenerated by irradiating with visible light and the strategy employed in this study is schematically illustrated in Scheme 1.
Journal ArticleDOI
Adsorption-induced scission of carbon–carbon bonds
Sergei S. Sheiko,Frank C. Sun,Adrian Randall,David Shirvanyants,Michael Rubinstein,Hyung-il Lee,Krzysztof Matyjaszewski +6 more
TL;DR: It is shown that simple adsorption of brush-like macromolecules with long side chains on a substrate can induce not only conformational deformations, but also spontaneous rupture of covalent bonds in themacromolecular backbone.
Journal ArticleDOI
Properties of Graphene/Waterborne Polyurethane Nanocomposites Cast from Colloidal Dispersion Mixtures
Sang Hyop Choi,Dong-Hoon Kim,Anjanapura V. Raghu,Kakarla Raghava Reddy,Hyung-il Lee,Koo Sik Yoon,Han Mo Jeong,Byung Kyu Kim +7 more
TL;DR: In this article, a colloidal dispersion of functionalized graphene sheets and waterborne polyurethane (WPU) was used to construct a nanocomposite with enhanced electrical conductivity and thermal resistance.
