Temperature can control a lock-and-key self-assembly mechanism
A group of Lund University researchers including Peter Schurtenberger have published a paper demonstrating that they can use oppositely charged thermoresponsive particles with complementary shapes, such as spherical and bowl-shaped particles, to implement an externally controllable lock-and-key self-assembly mechanism. The goal is to have the particles self-organize in order to make complex structures.
