Smart gating membrane based on polyzwitterion-modified SiO2 nanoparticles for water treatment and in-situ multi-modal detection

Revolutionizing targeting precision: microfluidics-enabled smart microcapsules for tailored delivery and controlled release

“…Depending on whether the gate materials are incorporated after or during membrane formation, the fabrication approaches for smart gates can be classified into two classifications: “grafting” techniques and “blending” techniques. Although a concentrated effort has been made to highlight smart gating membranes by bulk grafting or blending, 259–261 only few articles have focused on microfluidics-assisted smart gating membranes for controlled release. One point that needs to be clarified in advance is that porous microcapsules are not the focus of this section although they may be referred to as smart gating porous particles in other papers.…”

The design of multi-functional ionic hydrogels with anti-freezing, temperature response and luminescence properties

“…At the same time, some designs of the chemical structure of zwitterionic monomers also enable them to have richer functions. Wang et al 25 synthesized a polyzwitterion 2-(1-(4-vinylbenzyl) pyridin-1-ium-4-yl) ethane-1-sulfonate (PVPES), which contained a pyridine group and exhibits strong aggregation-induced emission (AIE). 26 This zwitterionic polymer which follows the AIE mechanism shows good application prospects in the detection of heavy metal ions and pH values.…”
