In summary, nanowired human cardiac organoids significantly augment the therapeutic potential of hPSC-CMs for heart repair. While cardiac organoids have been used for cardiac tissue engineering applications, this study reveals e-SiNWs as a class of biocompatible, conductive nanomaterials that facilitate contractile and noncontractile benefits in hPSC-CM transplantation. Given the emerging clinical applications of hPSC-CMs to treat infarcted hearts, these results have direct translational impacts for conductive nanomaterials in cardiac cell therapy and implications in other conductive tissues (e.g., skeletal muscle and neuronal tissues).

In this work, we show that the periplasm, an underappreciated subcellular region in materials research, can offer a nongenetic pathway for biomineralization of metastable semiconductor nanoclusters. Under light stimulation, the metastable semiconductor nanoclusters could couple with the electron transport chain to increase ATP levels and enhance malate production in the living hybrids. Using the E. coli strain as a model, the current system to develop periplasmic biointerface for enhanced solar-to-chemical production might be extended to other bacterial cells to potentially endow additional sustainability level to the bioremediation applications

We designed a soil-inspired chemical system that consists of nanostructured minerals, starch granules and liquid metals. The soil-inspired material possesses chemical, optical and mechanical responsiveness to yield write–erase functions in electrical performance. The composite can also modulate bacterial growth both in vitro and in vivo, such as enriches gut bacteria diversity, rectifies tetracycline-induced gut microbiome dysbiosis and ameliorates dextran sulfate sodium-induced rodent colitis symptoms within rodent models.

In this work, we showed that a porosity-based heterojunction, a largely overlooked system in materials science, can yield an efficient photoelectrochemical response from the semiconductor surface.

In this work, we identified several soft- hard composite designs in naturally occurring systems, and we use these designs to categorize the existing bioelectric interfaces and to suggest future opportunities in bioelectric studies.

In this review, we systematically summarize the attributes, fabrication methods, and applications of gallium-based liquid metal particles. Existing challenges and future opportunities regarding liquid metal particles are discussed herein.

We designed a liquid metal based composite that can change from non-conductive states to fully conductive states with mechanical pressure. Therefore, we can simply use a pen to create arbitrary conductive circuits on a soft substrate.

We presented a completely soft, stretchable silicone composite doped with thermochromic pigments and innervated with liquid metal. The ability to deform the liquid metal couples geometric changes to Joule heating, thus enabling tunable thermo-mechanochromic sensing of touch and strain.

We developed a super facile way to pattern liquid metal into complicated microstructures with branches and dead-ends. The process only took less than 1 minute.

We described here a light-fueled liquid-metal transformer for effective endosomal escape-facilitated cargo delivery via a chemical-mechanical process. Such liquid metal transformer could absorb and convert photoenergy to drive the simultaneous phase separation and morphological transformation from nanospheres to hollow nanorods to promote endosomal escape of payloads.
