Supramolecular Nanoarchitectonics of PNIPAAM‐co‐MA and Imogolite to Obtain Thermoresponsive Clay Nanotubes Through Complexation Mechanism

Advanced Materials Interfaces
In this study, the colloidal properties of hybrids formed by imogolite nanotubes (INTs) and poly(N‐isopropylacrylamide)‐co‐methacrylic (PNIPAAM‐co‐MA) are investigated, which is a thermo‐sensitive copolymer suitable for drug delivery applications.

Simulation of controllable permeation in PNIPAAm coated membranes

SPIE Proceedings, 2016
Membranes separate fluid compartments and can comprise transport structures for selective permeation. In biology, channel proteins are specialized in their atomic structure to allow transport of specific compounds (selectivity). Conformational changes in protein structure allow the control of the permeation abilities by outer stimuli (gating).

Using embedded alginate microparticles to tune the properties of in situ forming poly(N‐isopropylacrylamide)‐graft‐chondroitin sulfate bioadhesive hydrogels for replacement and repair of the nucleus pulposus of the intervertebral disc

JOR Spine, 2021
Low back pain is a major public health issue associated with degeneration of the intervertebral disc (IVD). The early stages of degeneration are characterized by the dehydration of the central, gelatinous portion of the IVD, the nucleus pulposus (NP ...

Selective adsorption of oppositely charged PNIPAAM on halloysite surfaces: A route to thermo-responsive nanocarriers

, 2018
Halloysite nanotubes were functionalized with stimuli-responsive macromolecules to generate smart nanohybrids. Poly(N-isopropylacrylamide)-co-methacrylic acid (PNIPAAM-co-MA) was selectively adsorbed into halloysite lumen by exploiting electrostatic ...

Cononsolvency‐Assisted Fabrication of Hydrogels and Microgels With Tunable Porosity, Diffusivity and Stiffness

Macromolecular Rapid Communications, Volume 47, Issue 21, 6 November 2026.
The cononsolvency of poly(dimethyl acrylamide‐co‐hydroxyethyl acrylamide) copolymers in water‐acetonitrile mixtures enables the synthesis of hydrogels with finely tuned porosity. Optimized for droplet‐based microfluidics, this approach facilitates the fabrication of porous microgels with tunable mechanical and diffusion properties, offering precise ...
