Alan O Burts et al.
Macromolecular rapid communications, 35(2), 168-173 (2013-11-23)
This report describes the synthesis of miktoarm brush-arm star polymers (BASPs) from branched and linear norbornene-terminated macromonomers (MMs) via the brush-first ring-opening metathesis polymerization (ROMP) method. First, a polystyrene (PS)-branch-poly(lactic acid) (PLA) MM is synthesized via a combination of atom
Folic acid-decorated and PEGylated PLGA nanoparticles for improving the antitumour activity of 5-fluorouracil.
International Journal of Pharmaceutics, 516(1-2), 61-70 (2017)

Macromolecules, 43(24), 10326-10335 (2011-05-03)
Graft-through ring-opening metathesis polymerization (ROMP) using ruthenium N-heterocyclic carbene catalysts has enabled the synthesis of bottle-brush polymers with unprecedented ease and control. Here we report the first bivalent-brush polymers; these materials were prepared by graft-through ROMP of drug-loaded polyethylene-glycol (PEG)
Angela X Gao et al.
ACS macro letters, 3(9), 854-857 (2014-09-23)
A panel of acid-labile bis-norbornene cross-linkers was synthesized and evaluated for the formation of acid-degradable brush-arm star polymers (BASPs) via the brush-first ring-opening metathesis polymerization (ROMP) method. An acetal-based cross-linker was identified that, when employed in conjunction with a poly(ethylene

Stimuli-responsive multimodality imaging agents have broad potential in medical diagnostics. Herein, we report the development of a new class of branched-bottlebrush polymer dual-modality organic radical contrast agents--ORCAFluors--for combined magnetic resonance and near-infrared fluorescence imaging in vivo. These nitroxide radical-based nanostructures

Photochemistry and photobiology, 90(2), 380-385 (2013-10-15)
New strategies for the synthesis of multifunctional particles that respond to external stimuli and release biologically relevant agents will enable the discovery of new formulations for drug delivery. In this article, we combine two powerful methods: brush-first ring-opening metathesis polymerization
Jenny Liu et al.
Journal of visualized experiments : JoVE, (80)(80), doi:10-doi:10 (2013-10-23)
Convenient methods for the rapid, parallel synthesis of diversely functionalized nanoparticles will enable discovery of novel formulations for drug delivery, biological imaging, and supported catalysis. In this report, we demonstrate parallel synthesis of brush-arm star polymer (BASP) nanoparticles by the

Journal of the American Chemical Society, 133(3), 559-566 (2010-12-15)
The combination of highly efficient polymerizations with modular "click" coupling reactions has enabled the synthesis of a wide variety of novel nanoscopic structures. Here we demonstrate the facile synthesis of a new class of clickable, branched nanostructures, polyethylene glycol (PEG)-branch-azide
Longyan Liao et al.
Journal of the American Chemical Society, 136(16), 5896-5899 (2014-04-15)
The synthesis of polymer therapeutics capable of controlled loading and synchronized release of multiple therapeutic agents remains a formidable challenge in drug delivery and synthetic polymer chemistry. Herein, we report the synthesis of polymer nanoparticles (NPs) that carry precise molar
