Swelling of Thermo-Responsive Gels in Aqueous Solutions of Salts: A Predictive Model

Molecules, 2022
The equilibrium degree of swelling of thermo-responsive (TR) gels is strongly affected by the presence of ions in an aqueous solution. This phenomenon plays an important role in (i) the synthesis of multi-stimuli-responsive gels for soft robotics, where ...

Design of Stimuli-Responsive Gels and Their Applications

NIPPON GOMU KYOKAISHI, 2005
Stimuli-responsive gels have attracted considerable attention as smart materials in the biochemical and biomedical fields, since they can sense environmental changes and induce structural changes by themselves. This paper provides an overview of the important research regarding the design and applications of stimuli-responsive gels that undergo volume ...

Stimuli Responsive Poly(Vinyl Caprolactam) Gels for Biomedical Applications

Gels, 2016
Poly(vinyl caprolactam) (PNVCL) is one of the most important thermoresponsive polymers because it is similar to poly(N-isopropyl acrylamide). PNVCL precipitates from aqueous solutions in a physiological temperature range (32–34 °C). The use of PNVCL instead of PNIPAM is considered advantageous because of the assumed lower toxicity of PNVCL.

Oscillating chemical reactions enable communication between responsive hydrogels

Physical Review Research
Responsive hydrogels can sense environmental stimuli and respond as actuators by expelling water and changing shape. In this Letter, we develop theory to demonstrate that groups of responsive hydrogels can also communicate with each other, by utilizing ...

Peptide‐Peptide Nucleic Acid Hybrid Hydrogel Based on Sequence Programmable Morphological Change for DNA Data Storage

Small Structures
Peptide‐based hydrogels provide biocompatible, stimuli‐responsive platforms, while peptide‐DNA hybrids extend programmability through hybridization‐driven crosslinking. However, nucleobase incorporation can influence peptide self‐assembly pathways.
