| Popis: | 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(N-isopropylacrylamide)-r-(N-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. |
