We are interested in developing chemistry that introduces life-like behavior in synthetic matter: from molecular building blocks to function at mesoscale.

Just out in Small @AdvSciNews . This time, we got inspired by an intriguing analogy to morphogenesis of “French flag”-patterns in nature. We demonstrate positional information-based self-organization of swarms of our surfactant microdroplets, which adapt..

Very proud to be part of this fantastic collaboration with @cnadirkaplan, published in @PhysRevLett! Diffusiophoretic Fast Swelling of Chemically Responsive Hydrogels. #hydrogels #actuators #responsivematter #nonequilibrium
We propose that the well-known concept of colloidal diffusiophoresis can also be manifested in hydrogels, offering a way to speed up gel deformations (that can otherwise be really slooow).

Hence, selective adhesion of filaments to the droplet’s front causes it to orbit around a stationary center droplet.

Just out in @ACS_Langmuir: our latest paper with more mechanistic insight into the self-organization of our amphiphile filaments and droplets at an air-water interface – emerging from Marangoni and elastocapillary effects.
