In our lab, we study how chemical and physical information can be incorporated into nano and microscale systems, and what is the relationship between information, structure and function. 

Our research interests include:
  • Stimuli responsive micro and nanosystems
  • 1-D to 3-D folding in the nanoscale
  • Reversible self-assembly
  • Chemical reactions in confined environments 
  • Multi-compartmental organic and inorganic nanoparticles
  • Chemical information in micro and nanoscale systems

One of the frustrating things in science is when Mother Nature decides to shove in and literally break down your perfect fibers. That’s what happened to Nicole Edelstein-Perdo, my joint student with Prof. Roey Amir, but she showed Mother Nature and published a great paper about it!
Congrats Nicole and the team for an exciting paper, in collaboration with Roey Amir’s and Roy Beck Barkai’s groups at Tel Aviv University, just published in Chemistry of Materials.

Together with the Markovich Lab, we present the transformation of thin polymer fibres and fabrics into conductive materials by in situ growth of a thin, optically transparent gold–silver nanowire (NW) mesh directly on the surface of polymer fibres. we show that the NW network morphology depends on the diameter of the polymer fibres, where at small diameters (1–2 μm), the NWs form a randomly oriented network, but for diameters above several micrometers, the NWs wrap around the fibres transversally. This phenomenon is associated with the stiffness of the surfactant templates used for the NW formation. The approach demonstrated in this work can be extended to other polymeric fibres and could be useful for various smart electronic textile applications.

We present the fabrication of highly-ordered 2D networks hierarchically constructed of thermoresponsive mesoscale polymeric fibers, which can exhibit morphing with microscale resolution. The morphing of such networks strongly dependson two intrinsic length scales - the fiber diameter and mesh size. Depending on these parameters, such fiber-networks exhibit one of two thermally driven morphing behaviors: i)the fibers stay straight, and the network preserves its ordered morphology; or ii) the fibers buckle and the network becomes messy and highly disordered. Notably, in both cases, the networks display memory and regain their original ordered morphology upon shrinking.

We demonstrate a general scheme for fabricating freestanding Metal–organic frameworks (MOFs)-embedded polymeric fibers, in which the fibers themselves act as microreactors for the in situ growth of the MOF crystals. We demonstrate that immobilizing enzymes  on such MOF-polymer fibers improves their performance and enhances the enzyme's stability.
