Porous polymer monolithic column with surface-bound gold nanoparticles for the capture and separation of cysteine-containing peptides
TL;DR: A new porous polymer monolithic capillary column modified with gold nanoparticles that enables the selective capture of cysteine-containing peptides has been developed to reduce the complexity of peptide mixtures generated in bottom-up proteomic analysis.
Acetal-modified dextran microparticles with controlled degradation kinetics and surface functionality for gene delivery in phagocytic and non-phagocytic cells.
Joel A. Cohen,Tristan T. Beaudette,Jessica Cohen,Kyle E. Broaders,Eric M. Bachelder,Jean M. J. Fréchet +5 more
TL;DR: A tunable and modular microparticle system for plasmid delivery is reported that would overcome problems and simultaneously allow the systematic study of the dependence of transfection efficiency on various formulation parameters including degradation kinetics, use of cationic blend polymers, and surface functionalization for the transfections of non-phagocytic cells.
Preparation of Porous Poly(styrene-co-divinylbenzene) Monoliths with Controlled Pore Size Distributions Initiated by Stable Free Radicals and Their Pore Surface Functionalization by Grafting
TL;DR: A stable free radical mediated preparation of porous poly(styrene-co-divinylbenzene) monoliths using new types of SFRs and a novel binary porogenic solvent consisting of poly(ethylene glycol) was proposed in this article.
Fully Acid-Degradable Biocompatible Polyacetal Microparticles for Drug Delivery
Sergey E. Paramonov,Eric M. Bachelder,Tristan T. Beaudette,Stephany M. Standley,Cameron C. Lee,Jesse Dashe,Jean M. J. Fréchet +6 more
TL;DR: The ease of preparation of the polymers coupled with the ability to tune their hydrophobicity and the high acid sensitivity of the microparticles identify this new class of materials as promising candidates for the delivery of bioactive materials.

TL;DR: For a wide range of photovoltaic devices based on polymer:fullerene, small-molecule:C60 and polymer:polymer blends, the study reveals that the internal quantum efficiency is essentially independent of whether or not D, A or CT states with an energy higher than that of CT1 are excited.
