The amphiphilic nature of silk fibroin makes it a natural surfactant. Here it is shown to mediate interface interactions, enabling the wetting of hydrophobic surfaces with aqueous solutions and facilitating water-processed nanodevice fabrication without previous surface modification.

Electrical stimulation of astrocytes using electrodes coated with graphene oxide and reduced graphene oxide can be used to trigger specific calcium signals.

Wearable contact lens can be used for health monitoring applications such as intraocular pressure for glaucoma and postoperative myopia. Here, Liu et al. report a neuroprosthetic contact lens-enabled sensorimotor system with a sensitivity of 12.52 mV mmHg−1 for point-of-care monitoring and real-time display.

Infarted myocardium hampers the synchronous electroactivity of the cardiac tissue. Here, the authors showcase a battery-free conductive cardiac patch made of reduced graphene and its therapeutic efficacy for cardiac repair.

The utility of wet-tissue adhesives has been impeded by the suboptimal adhesive strength. Here the authors report a composite patch integrated with BP nanosheets that improve the wet-tissue adhesion by enhancing the water absorption and mechanical properties of the patch and demonstrate the uses of the patch in hemostasis, physical-activity monitoring and tumour-recurrence prevention.

A flexible, biodegradable and self-powered electronic bandage is designed to deliver dual-mode electrical stimulation, which can synergistically accelerate local intestinal wound healing. This approach also shows promise for reducing postoperative complications and could have broad potential for application in other tissues and organs.

Using fluorinated elastomers in the fabrication of soft neural probes is shown to enhance spatiotemporal recording capability at single-neuron resolution within the central nervous system of rodents. Other soft encapsulation materials could be similarly engineered for high-resolution, long-lasting bioelectronics.

Miniaturized power sources consisting of a few droplets can generate enough power to modulate neuronal activity.

An article in Science reports a co-polymer with both semiconducting and adhesive properties, which can effectively stick an organic electrochemical transistor (OECT)-based sensor to living tissues.
