Islam, Molla R., Serpe, Michael J.

Dual pH and temperature sensitive microgel-based etalons were fabricated by sandwiching a “monolithic” microgel layer between two semitransparent, Au layers. The devices exhibit visual color and multipeak reflectance spectra, both of which primarily depend on the distance between the Au surfaces...

Bernard, G.M., Michaelis, V.K.

The practicality of obtaining liquid‐ and solid‐state 207Pb nuclear magnetic resonance (NMR) spectra with a low permanent‐field magnet is investigated. Obtaining 207Pb NMR spectra of salts in solution is shown to be viable for samples as dilute as 0.05 M. The concentration dependence of the 207Pb...

Gao, Yongfeng, Serpe, Michael J.

Poly(N-isopropylacrylamide) (pNIPAm) microgel-based etalons were used to fabricate systems that change visual color in response to light exposure. These systems were fabricated by adding pH responsive microgel-based etalons to a solution composed of the photoacid o-nitrobenzaldehyde (o-NBA). Upon...

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...

The application of hydrogen/deuterium exchange mass spectrometry (HDX-MS) to localize ligand binding sites in carbohydrate-binding proteins is described. Proteins from three bacterial toxins, the B subunit homopentamers of Cholera toxin and Shiga toxin type 1 and a fragment of Clostridium...

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...

Klassen, John S., Deng, Lu, Kitova, Elena N.

Intermolecular interactions in the gaseous ions of two protein–ligand complexes, a single chain antibody (scFv) and its trisaccharide ligand (α-D-Galp-(1→2)-[α-D-Abep-(1→3)]-α-Manp-OCH3, L1) and streptavidin homotetramer (S4) and biotin (B), were investigated using a collision-induced...
