Region-dependent volumetric oscillation of self-oscillating gels with gradient transducers

Abstract: Heartbeats with different ventricular contraction vary with heart regions, which can be described as anisotropy. Herein, we report self-oscillating gels which exhibit region-dependent anisotropic volumetric oscillation behavior similar to that...

“…The additional option is to locally control the amount of conjugated Ru(bpy) 3 in the C-SOGs, which can critically impact the propagating behavior of the BZ chemical wave. 28,31,39 In every case, we strongly believe that the C-SOG system in this study has definite potential as an experimental model for CMFs.…”

“…25–27 Since the current Ru(bpy) 3 –NHS concentration ( i.e. , 70 mM) could lead all primary amine groups to saturatedly react with Ru(bpy) 3 –NHS molecules, 25,27,28 the C-SOGs with a thicker layer can imply that more Ru(bpy) 3 might be conjugated than the C-SOGs with a thinner layer. Therefore, the equilibrated thickness difference between the redox states could depend on the gel layer thickness.…”

“…[11][12][13][14][15][16] From this viewpoint, the SOGs are promising candidates that exhibit autonomous shape deformation. Even though the SOGs have been used to realize various biological functions, including cilia movement, 17 intestines-like peristalsis, 18 and the distinguished beating between the two heart ventricles, 19 cardiomyocyte-like anisotropic beating has not been developed yet. Cardiomyocytes beat more in the longitudinal direction versus the transverse direction.…”

“…In this study, we realized the controllable SOG system featuring cardiomyocyte-like anisotropic deformations during the BZ reaction. Anisotropically deforming gel systems have been fabricated by realizing a concentration gradient of crosslinker 17 or catalyst, 19,22 and 3D printing of a heterogeneous gel composite. 23,24 In this study, we utilized a spatially patterned secondary interpenetrating polymer network (IPN) at both ends of the sheet-based SOGS to make cardiomyocyte-like anisotropic deformation (Fig.…”
