4D Materials of Tough and Rapid Thermoresponsive Hydrogel by PET‐RAFT Polymerization

Journal of Applied Polymer Science, EarlyView.
NIPAm‐containing bilayer hydrogels using a novel hydrogel formation method utilizing oxygen‐tolerant PET‐RAFT polymerization to investigate their temperature‐responsive behavior. The material properties strongly depend on NIPAm concentration and polymer density. Finally, we demonstrated a model gripper with optimized compositions.

Process Optimization of Solution Blow Spinning for Poly (N‐Isopropylacrylamide) Fibers

Journal of Applied Polymer Science, EarlyView.
Solution blow spinning has emerged as a safe and scalable technique for fabricating thermoresponsive PNIPAM fibers. The influence of key parameters on jet stability and fiber uniformity is determined through both rheological analysis and statistical process optimization. A Box–Behnken design reveals an optimized window for producing PNIPAM fibers below

Hemozoin-catalyzed precipitation polymerization as an assay for malaria diagnosis

Nature Communications, 2019
Methods to diagnose malaria are of interest but can be costly or not sensitive enough to detect low levels of parasitemia. Here the authors report an ultrasensitive method by using hemozoin (a biomarker of all Plasmodium species) to catalyse the ...
