Journal ArticleDOI
Writing Self‐Erasing Images using Metastable Nanoparticle “Inks”
TL;DR: A conceptually differentSelf-erasing material in which both the “writing” and self-erasure of color images are controlled by the dynamic non-equilibrium aggregation of photoresponsive metal nanoparticles embedded in thin, flexible organogel films.
Journal ArticleDOI
Maze Solving by Chemotactic Droplets
TL;DR: Droplets emitting surface-active chemicals exhibit chemotaxis toward low-pH regions and navigate through a complex maze to seek a source of acid placed at one of the maze's exits to find the shortest path through the maze.
Journal ArticleDOI
Contact Electrification between Identical Materials
TL;DR: A theoretical model is presented that explains these phenomena by the inherent, molecular-scale fluctuations in the composition of the seemingly identical contacting surfaces.
Journal ArticleDOI
Metal nanoparticles functionalized with molecular and supramolecular switches.
Rafal Klajn,Lei Fang,Ali Coskun,Mark A. Olson,Paul J. Wesson,J. Fraser Stoddart,Bartosz A. Grzybowski +6 more
TL;DR: Weakly protected metal nanoparticles are used as precursors for the preparation of catenane- and pseudorotaxane-decorated NPs of various compositions (gold, palladium, platinum).
Journal ArticleDOI
Dynamic hook-and-eye nanoparticle sponges
Rafal Klajn,Mark A. Olson,Paul J. Wesson,Lei Fang,Ali Coskun,Ali Trabolsi,Siowling Soh,J. Fraser Stoddart,Bartosz A. Grzybowski +8 more
TL;DR: Polymers that capture and release functionalized nanoparticles selectively during redox-controlled aggregation and disaggregation, respectively are described.
