Hydrogel microwells with light-controlled reversible closure
Qifei Ma, David Urban, Stefano Gabetti +8
We present a light-responsive hydrogel nanocomposite engineered into arrays of micrometer-scale wells that can be selectively and sequentially closed and re-opened via laser illumi…

Tunable topological edge modes in Su-Schrieffer-Heeger arrays
G. J. Chaplain, A. S. Gliozzi, B. Davies +4
A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtai…
