Core-shell microgel (CSMG) nanoparticles, also referred to as core-cross-linked star (CCS) polymers, can be envisaged as permanently cross-linked block copolymer micelles and, as such, afford novel opportunities for chemical functionalization, templating, and encapsulation. In this study, we explore the behavior of CSMG nanoparticles comprising a(More)
Non-planar non-cracking honeycomb (HC) structures are prepared from star polymers with high glass transition temperatures (T(g) ) and relatively low Young's moduli (E). This study demonstrates that the Young's modulus of a polymer is a more important factor than the glass transition temperature for determining the occurrence of cracking during HC film(More)
A novel reduced iron metal-organic framework nanoparticle with cytotoxicity specific to cancer cells is presented. This nanoparticle was prepared via a hydrothermal method, reduced using hydroquinone, and finally conjugated with folic acid (namely, rMOF-FA). The synthesized nanoparticle shows the controlled release of iron in an acidic ex-vivo environment.(More)
The effect of glass transition temperature, Tg, on the self-assembly of "honeycomb" microstructures on nonplanar substrates was probed by the synthesis of a library of core cross-linked star polymers with different arm compositions. Star polymers based on poly(dimethyl siloxane), poly(ethyl acrylate), poly(methyl acrylate), poly(tert-butyl acrylate), and(More)
