Microfluidics-Assisted Synthesis of Cross-Linked Colloidosomes with Multisensitive Behaviors: A Potential Platform for Photo Memory Device and Blue-Light-Triggered Release Vehicle

Uniformly sized and cross-linked colloidosomes were prepared via microfluidic emulsification combined with a post-cross-linking reaction between NH₂/ruthenium dual-functionalized microgels and poly­(<i>N</i>-isopropylacrylamide)-r-(<i>N</i>-acryloxysuccinimide)-based polymers. When mixed with catalyst-free Belousov–Zhabotinsky reaction substrates, the colloidosomes first experienced decrease in size and then exhibited mechanical oscillations. In addition, the colloidosome behavior can be regulated using different types of light, which then displayed reversible deswelling/swelling cycles under alternating white light on/off stimuli, but only expanded and even ruptured under the stimulus of continuous blue light illumination. These multisensitive colloidosomes could be potentially applied in the fields of photo memory devices and blue light-triggered release vehicles

Microfluidics Fabrication of Self-Oscillating Microgel Clusters with Tailored Temperature-Responsive Properties Using Polymersomes as “Microreactors”

Poly­(<i>N</i>-isopropylacrylamide)-based microgel clusters were successfully prepared using polymersomes as “microreactors”, which were fabricated through microfluidics. The clusters were formed from the cross-linking reaction between ruthenium/amino group dual functionalized poly­(<i>N</i>-isopropyl­acrylamide) microgels and linear poly­(<i>N</i>-isopropyl­acrylamide)-<i>r</i>-(<i>N</i>-acryloxy­succinimide)-based polymer linkers under neutral pH conditions. By simply adjusting the ratio of <i>N</i>-isopropyl­acrylamide to <i>N</i>-acryloxy­succinimide in the polymer cross-linkers, the internal structures of the clusters can be controlled; hence, the temperature response of the clusters can be regulated. It was demonstrated that these different microgel clusters showed various degrees of chemomechanical oscillations when the clusters were exposed to a catalyst-free solution containing Belousov–Zhabotinsky reaction substrates
