Journal ArticleDOI
Nanoscale Forces and Their Uses in Self‐Assembly
TL;DR: This Review provides a critical examination of the various interparticle forces (van der Waals, electrostatic, magnetic, molecular, and entropic) that can be used in nanoscale self-assembly.
Journal ArticleDOI
The Mosaic of Surface Charge in Contact Electrification
Hasan Tarik Baytekin,Alexander Z. Patashinski,Michal Branicki,Bilge Baytekin,Siowling Soh,Bartosz A. Grzybowski +5 more
TL;DR: It is demonstrated that each contact-electrified piece develops a net charge of either positive or negative polarity, and each surface supports a random “mosaic” of oppositely charged regions of nanoscopic dimensions that accommodate significantly more charge per unit area than previously thought.
Journal ArticleDOI
Directing cell motions on micropatterned ratchets
Goher Mahmud,Christopher J. Campbell,Kyle J. M. Bishop,Yulia Komarova,Oleg Y. Chaga,Siowling Soh,Sabil Huda,Kristiana Kandere-Grzybowska,Bartosz A. Grzybowski +8 more
TL;DR: This article demonstrates that random motions of motile cells can be rectified by asymmetric (‘ratchet’) microgeometries and observations that the direction of preferred motion can be different for different species of cell are provided.
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
Drug delivery systems for programmed and on-demand release.
TL;DR: The past and current techniques available for fabricating and remotely controlling drug delivery systems are reviewed and the application of new technologies (e.g. 3D printing) in this field are addressed.
