  • Temperature-responsive janus hydrogel microparticles by centrifuge-based microfluidic device

抄録

This paper describes temperature responsive janus hydrogel micro particles that can encapsulate various materials. Using a centrifuge based microfluidic device we fabricated the micro particles. The micro particles were made from sodium alginate and poly (N-Isopropylacrylamid) (pNIPAM) so they were able to shrink when the temperature rises. We measured the shrinkage ratio of the particles and it was about 0.91. Furthermore we measured the strength of fluorescence of the janus particle and confirmed that it was compartmentalized. We believe that our micro particles could be applied to actuators for soft robots and sustain release of drug for drug delivery system.
