Incorporation of a ‘liquid diode’ into a wearable electronic platform enhances comfort and stability by shunting away sweat as it accumulates.

3D-printed glass holds great potential. However, it is challenging to control both the dimension and the resolution of the printed material. Here, authors present a one-photon 3D printing approach to produce high-performance fused silica glass with sub-micron resolution and millimetric dimensions.

Nanofluidic devices with a large entrance asymmetry can function as memristive switches—operating on the second timescale and with a conductance ratio of up to sixty—and can be assembled into basic logic circuits.

Functional features in the spatiotemporal regulation of blood chemistry are not much explored. Here authors show vascular network-inspired fluidics, functionalizable for different region-specific trans-wall transport to regulate fluids over space and time.

Building liquid devices from solid enclosing walls can be costly and lack reconfigurability. Now the rapid construction and reconfiguration of diverse liquid devices is demonstrated through assembly and disassembly of droplet arrays in a pillared substrate.

Liquid metals are promising multifunctional materials, but their single-colour physical appearance limits their applicability. There are several methods to endow liquid metals with colour and fluorescence, and although breakthroughs have been made in controlling their optical and interfacial properties, more work is needed to refine the synthetic strategies, better understand the coloration effects and enable the applications of colourful liquid metals.

An article in Advanced Healthcare Materials reports a tumour-on-a-chip platform for the high throughput-screening of cancer drugs.
