Publikováno v: Macromolecular Bioscience. 11:927-937

We present a general approach for the selective imaging and killing of cancer cells using protein-activated near-infrared emitting and cytotoxic oxygen generating nanoparticles. Poly(propargyl acrylate) (PA) particles were surface modified through th

Publikováno v: Synthetic Metals. 160:2486-2493

An electron-transporting monomer was synthesized that was structurally and energetically similar to the small molecule 2-biphenyl-4-yl-5-(4- tert -butylphenyl)-1,3,4-oxadiazole (tBu-PBD). The monomer was copolymerized with 2-(9 H -carbazol-9-yl)ethyl

Reversible crosslinking density stimulated diffraction wavelength tuning of hydrogel-encapsulated crystalline colloidal arrays

Autor: Ye Dai, Parul Rungta, Stephen H. Foulger, Hua Bao, Jiaping Lin

Publikováno v: Journal of colloid and interface science. 377(1)

The reversible variation in the observed stop band of a hydrogel-encapsulated crystalline colloidal array was achieved through the selective formation and destruction of –S–Pb–S– linkages within the hydrogel. A reversible 45 nm stop band shif

Comparative study on the effect of thermal annealing on polymer/small molecule blend and copolymer light-emitting devices

Autor: Michael A. Daniele, Yuriy Bandera, Parul Rungta, Stephen H. Foulger, Volodymyr Tsyalkovsky

Publikováno v: Organic Photonic Materials and Devices XII.

The intrinsic deterioration in device performance of polymeric single layer OLEDs that were doped with a fluorescent emitter was studied. The specific focus was on the role that thermal aging, at sub-glass transition temperatures of the polymeric lay

Dynamics of percolation phenomena in colloidal printing inks

Autor: Michael A. Daniele, Alexandra L. Foguth, Iurii Bandera, Parul Rungta, Volodymyr Tsyalkovskyy, Stephen H. Foulger

Publikováno v: SPIE Proceedings.

The conductivity of colloidal inks composed of poly(ethylene glycol) (PEG), 2-(4-tert-Butylphenyl)-5-(4-biphenylyl)- 1,3,4-oxadiazole (tPBD) or polystyrene-tPBD copolymerized colloids (PS-PBD) and carbon black (CB) were investigated to establish thei

Colloidal templating: seeded emulsion polymerization of a soluble shell with a controlled alkyne surface density

Autor: Volodymyr Tsyalkovskyy, Yurii Bandera, Parul Rungta, Stephen H. Foulger, Ryan D. Roeder

Publikováno v: Soft Matter. 8:5493

A general methodology for producing ca. 100 nm core–shell colloidal particles in which the shell has an elevated alkyne functionality and yet remains thermoplastic is presented. The availability of accessible alkyne groups on the surface of the aqu

Designing fluoroprobes through Förster resonance energy transfer: surface modification of nanoparticles through 'click' chemistry

Autor: Parul Rungta, Volodymyr Tsyalkovsky, Yuriy Bandera, Stephen H. Foulger

Publikováno v: Soft Matter. 6:6083

Aqueous-phase 83 nm poly(propargyl acrylate) (PA) nanoparticles were surface-functionalized with sparingly water soluble fluorescent moieties through a copper(I)-catalyzed azide–alkyne cycloaddition (CuAAC) (i.e., “click” transformation) to pro
