Optical devices were fabricated by sandwiching a “monolithic” poly(N-isopropylacrylamide-co-N-(3-aminopropyl) methacrylamide hydrochloride) (pNIPAm-co-APMAH) microgel layer between two semitransparent Au layers. These devices, referred to as etalons, exhibit characteristic multipeak reflectance...

A versatile surface modification technique was developed to yield poly(N-isopropylacrylamide) (pNIPAm) microgel-based thin films on a variety of substrates, e.g., metals, nonmetals, and polymers. Because the chemistry, and hence functionality and responsivity, of the pNIPAm-based microgels is...

In this submission, we detail a new method for detecting mouse Immunoglobulin G (IgG) utilizing fluorophore-modified antibodies and antibody-modified magnetic microparticles. This was accomplished by adding an excess amount of fluorescein isothiocyanate (FITC)-modified goat anti-mouse IgG...

Saposin A (SapA) lipoprotein discs, also known as picodiscs (PDs), represent an attractive method to solubilize glycolipids for protein interaction studies in aqueous solution. Recent electrospray ionization mass spectrometry (ESI-MS) data suggest that the size and composition of...

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...

Li, Wenxiang, Hu, Liang, Zhu, Jinghua, Li, Dan, Luan, Yafei, Xu, Wenwen, Serpe, Michael J.
In this submission, the phase transition behavior for poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAm-co-AAc) microgels and their assemblies was investigated as a function of temperature and pH using UV–vis spectroscopy (to probe light scattering behavior) and quartz crystal microbalance with...

A device composed of a poly (N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgel layer sandwiched between two thin Au layers (all on a glass support) was used as a novel platform for controlled and triggered small molecule delivery. Tris (4-(dimethylamino)phenyl)methylium chloride...

Gao, Yongfeng, Ahiabu, Andrews, Serpe, Michael J.
In this submission, two independent sets of microgels were synthesized that exhibit pH responsivity over different solution pH ranges. The microgels were synthesized by copolymerizing two different comonomers with poly(N-isopropylacrylamide) (pNIPAm). The microgels copolymerized with acrylic acid...
