A series of pyridine-functionalized poly (N-isopropylacrylamide)- based microgels were synthesized. Subsequently, a structured photonic device was fabricated by sandwiching the microgels between two thin Au layers, and their response to CO2 investigated. We show that devices show an optical...

A device constructed by sandwiching a thin film of poly(N-isopropylacrylamide)-co-acrylic acid (pNIPAmco-AAc) microgels between two thin layers of Au (all on a glass support) was used as a novel platform for controlled release of small molecules (drugs). In this submission, the model drug tris...

Serpe, Michael J., Zhang, Qiang M., Li, Xue, Islam, Molla R., Wei, Menglian
4,40 -Di(acrylamido)-azobenzene was used as a crosslinker in poly(Nisopropylacrylamide)-based microgels. The microgels were subsequently used to fabricate microgel-based optical materials (etalons), which exhibited optical properties that were switchable upon exposure to UV irradiation. We also...

Berg, Darren, Mugo, Samuel M., Zhang, Qiang M., Serpe, Michael J.
Lipase-modified pH-responsive poly(N-isopropylacrylamide)-based microgels were synthesized. An optical device was subsequently fabricated by sandwiching the enzyme loaded responsive microgels between two thin Au layers, and their response to triolein, a model triglyceride, was investigated. The...

Anisotropic particles have generated an enormous amount of research interest due to their applications for drug delivery, electronic displays and as micromotors. However, up till now, there is no single protocol capable of generating particles of “patchy” composition with a variety of...

Zhang, Qiang M., Serpe, Michael J., Han, De-Man
Poly (N-isopropylacrylamide)-co-(acrylic acid) (pNIPAm-co-AAc) microgels composed of Ag nanoparticles (Ag NPs) have been synthesized and employed for the colorimetric sensing of H2O2. Each pNIPAmco-AAc microgel, which exhibited a diameter of ∼800 nm, contained multiple Ag NPs (diameter of ∼5 nm),...
