Photonic materials (PMs) that are capable of manipulating and controlling light in systems have immense potential for the computing and communications industries. These materials are formed by assembling components of differing refractive indices in a periodic array. Light then interacts with...
Comparison of the Responsivity of Solution-Suspended and Surface-Bound Poly (N-isopropylacrylamide)-Based Microgels for Sensing ApplicationsDownload
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...
Janus poly (N-isopropylacrylamide)-co-acrylic acid/Au microgels that resemble a “snowman”, “dumbbell”, and an “abalone” were prepared by thermally evaporating a layer of Au on half of the microgel surface, followed by exposure to thiolated single-stranded DNA with complementary sequences. We...
Poly (N-isopropylacrylamide) (pNIPAm) is one of the most completely studied “smart” polymers due to its unique reversible thermoresponsivity. That is, when pNIPAm in water is heated > ~31°C, it transits from a random coil to a globule conformation; this transition is reversed when T < ~31°C. This...
Stimuli-responsive polymers are capable of translating changes in their local environment to changes in their chemical and/or physical properties. This ability allows stimuli-responsive polymers to be used for a wide range of applications. In this review, we highlight the analytical applications...
The influence of deposition solution pH and ionic strength on the quality of poly (N-isopropylacrylamide) microgel-based thin films and etalonsDownload
Poly(N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgel-based thin films and etalons were fabricated via “painting” a pNIPAm-co-AAc microgel monolayer on a Au-coated substrate, followed by the deposition of another Au overlayer. Herein, in situ observation of how the pH and ionic...
