Stimuli-Responsive Behavior of PNiPAm Microgels under Interfacial Confinement [PDF]

Langmuir, 2019
The volume phase transition of microgels is one of the most paradigmatic examples of stimuli-responsiveness, enabling a collapse from a highly swollen microgel state into a densely coiled state by an external stimulus. Although well characterized in bulk, it remains unclear how the phase transition is affected by the presence of a confining interface ...

Thermoresponsive Fluorescence Switches Based on Au@pNIPAM Nanoparticles

Langmuir, 2021
Despite numerous studies emphasizing the plasmonic impact on fluorescence, the design of a dynamic system allowing on-demand fluorescence switching in a single nanostructure remains challenging. The reversibility of fluorescence switching and the versatility of the approach, in particular its compatibility with a wide range of nanoparticles and ...

Form factor of pNIPAM microgels in overpacked states

The Journal of Chemical Physics, 2014
We study the form factor of thermoresponsive microgels based on poly(N-isopropylacrylamide) at high generalized volume fractions, ζ, where the particles must shrink or interpenetrate to fit into the available space. Small-angle neutron scattering with contrast matching techniques is used to determine the particle form factor.
