Stable Freestanding Thin Films of Copolymer Melts Far from the Glass Transition.

ACS macro letters

Gaillard T, Poulard C, Voisin T, Honorez C, Davidson P, Drenckhan W, Roché M.
PMID: 26527410
ACS Macro Lett. 2015 Oct 20;4(10):1144-1148. doi: 10.1021/acsmacrolett.5b00535. Epub 2015 Oct 02.

Thin polymer films have attracted attention because of both their broad range of applications and of the fundamental questions they raise regarding the dynamic response of confined polymers. These films are unstable if the temperature is above their glass...

Cluster Glasses of Semiflexible Ring Polymers.

ACS macro letters

Slimani MZ, Bacova P, Bernabei M, Narros A, Likos CN, Moreno AJ.
PMID: 25083314
ACS Macro Lett. 2014 Jul 15;3(7):611-616. doi: 10.1021/mz500117v. Epub 2014 Jun 12.

We present computer simulations of concentrated solutions of unknotted nonconcatenated semiflexible ring polymers. Unlike in their flexible counterparts, shrinking involves a strong energetic penalty, favoring interpenetration and clustering of the rings. We investigate the slow dynamics of the centers-of-mass...

Experimental evidence of weak excluded volume effects for nanochannel confined DNA.

ACS macro letters

Gupta D, Miller JJ, Muralidhar A, Mahshid S, Reisner W, Dorfman KD.
PMID: 26664782
ACS Macro Lett. 2015 Jul;4(7):759-763. doi: 10.1021/acsmacrolett.5b00340. Epub 2015 Jul 02.

We present experimental demonstration that weak excluded volume effects arise in DNA nanochannel confinement. In particular, by performing measurements of the variance in chain extension as a function of nanochannel dimension for effective channel size ranging from 305 nm...

ATRP Synthesis of Sunflower Polymers using Cyclic Multimacroinitiators.

ACS macro letters

Wei H, Wang CE, Tan N, Boydston AJ, Pun SH.
PMID: 26900511
ACS Macro Lett. 2015 Sep 15;4(9):938-941. doi: 10.1021/acsmacrolett.5b00565. Epub 2015 Aug 17.

Polymers with advanced architectures can now be readily and reproducibly synthesized using controlled living polymerization. These materials are attractive as potential drug carriers due to their tunable size, versatile methods of drug incorporation and release, and ease of functionalization...

Conformations of a Long Polymer in a Melt of Shorter Chains: Generalizations of the Flory Theorem.

ACS macro letters

Lang M, Rubinstein M, Sommer JU.
PMID: 26543675
ACS Macro Lett. 2015 Feb 17;4(2):177-181. doi: 10.1021/mz500777r. Epub 2015 Jan 14.

Effect of Bending Rigidity on the Knotting of a Polymer under Tension.

ACS macro letters

Matthews R, Louis AA, Likos CN.
PMID: 23378936
ACS Macro Lett. 2012 Nov 20;1(11):1352-1356. doi: 10.1021/mz300493d. Epub 2012 Nov 08.

A coarse-grained computational model is used to investigate how the bending rigidity of a polymer under tension affects the formation of a trefoil knot. Thermodynamic integration techniques are applied to demonstrate that the free-energy cost of forming a knot...

Strain-Promoted Crosslinking of PEG-based Hydrogels via Copper-Free Cycloaddition.

ACS macro letters

Zheng J, Smith Callahan LA, Hao J, Guo K, Wesdemiotis C, Weiss RA, Becker ML.
PMID: 23205321
ACS Macro Lett. 2012 Aug 21;1(8):1071-1073. doi: 10.1021/mz3003775.

The synthesis of a 4-dibenzocyclooctynol (DIBO) functionalized polyethylene glycol (PEG) and fabrication of hydrogels via strain-promoted, metal-free, azide-alkyne cycloaddition is reported. The resulting hydrogel materials provide a versatile alternative in which to encapsulate cells that are sensitive to photochemical...

Supramolecular Polymers Formed by ABC Miktoarm Star Peptides.

ACS macro letters

Lin YA, Ou YC, Cheetham AG, Cui H.
PMID: 24490124
ACS Macro Lett. 2013 Dec 17;2(12):1088-1094. doi: 10.1021/mz400535g.

We report here the design and synthesis of an ABC miktoarm star peptide connecting through a lysine junction a short peptide sequence and two hydrophobic but immiscible blocks (a hydrocarbon and a fluorocarbon). The designed molecule can self-assemble into...

Resilin-based Materials for Biomedical Applications.

ACS macro letters

Li L, Kiick KL.
PMID: 23997990
ACS Macro Lett. 2013 Aug 20;2(8):635-640. doi: 10.1021/mz4002194.

Resilin, an insect structural protein, exhibits rubber-like elasticity characterized by low stiffness, high extensibility, efficient energy storage, and exceptional resilience and fatigue lifetime. The outstanding mechanical properties of natural resilin have motivated recent research in the engineering of resilin-like...

Advancing polymeric delivery systems amidst a nucleic acid therapy renaissance.

ACS macro letters

Burke PA, Pun SH, Reineke TM.
PMID: 24683504
ACS Macro Lett. 2013 Oct 15;2(10):928-934. doi: 10.1021/mz400418j.

Nucleic acid therapeutics are attracting renewed interest due to recent clinical advances and product approvals. Most leading programs use chemical conjugates, or viral vectors in the case of gene therapy, while several use no delivery system at all. Polymer...

Strategies to refine the degradation behavior of polyester biomaterials, particularly to overcome the limitations of slow hydrolytic degradation, would broaden their utility. Herein, we examine the complexities of polyester degradation behavior, its assessment and strategies for refinement. The factors...
