Rapid degradation inducing overdose toxicity remains challenging in porous biodegradable bone scaffolds. Here the authors present multiscale architecture design on ZnLi scaffolds with 90% porosity orchestrates immune responses and subsequent bone regeneration.

Manual processes to produce ocular prostheses are time-consuming and yield varying quality. Here, authors present an automatic digital end-to-end process for custom ocular prostheses. It creates shape and appearance from image data of an OCT device and produces them using a full-colour 3D printer.

The proper axial length of the eye is crucial for achieving emmetropia. Here, authors introduce a wireless battery-free eye modulation patch designed to correct high myopia and prevent relapse.

Cellular encapsulation holds promise for immunosuppression-free pancreatic islet transplantation. However, long-term graft survival remains a challenge, especially at the subcutaneous site. We harnessed temporary, controlled, inflammation-induced neovascularization to create a modified subcutaneous cavity that supports long-term survival and function of a customized islet encapsulation device without immunosuppression.

An article in Nature Communications reports a metamaterial-based textile that can be worn as clothing to enable direct implant-to-implant wireless networking at the scale of the human body.

Wearable electronics could enable us to optimize every aspect of our personal health and performance. They might also have important ramifications for clinical use and theranostics.

Lokwani et al. discuss the necessary considerations when performing spectral cytometry on highly autofluorescent samples to extract phenotypic information from autofluorescence spectra and perform accurate quantification of fluorescent labels.

The development of microelectromechanical systems that decompose after use expands the toolbox of transient electronics, a technology that could help reduce electronic waste.

Porcine dermal collagen was chemically and photochemically bioengineered into an implantable tissue mimicking the human corneal extracellular matrix. The implant presents a simpler and safer method than donor cornea transplantation while delivering equivalent outcomes, and has restored vision to people with advanced keratoconus in resource-limited regions, where the burden of blindness is highest.
