Developing composite materials with optimized mechanics, degradation, and bioactivity for bone regeneration has long been a crucial mission. Herein, a multifunctional Mg/Poly‐l‐lactic acid (Mg/PLLA) composite membrane based on the “materials plain” concept through the accumulative rolling (AR) method is proposed. Results show that at a rolling ratio of 75%, the comprehensive mechanical properties...
Fully integrated wearable electronics that combine the extraordinary feature of incessant and on‐body operation with the distinctive external equipment‐free trait are the ultimate goal of modern wearables. Epidermal sweat and wound exudate, as two noninvasively accessible biofluids on/surrounding the skin, reflect underlying health conditions. However, the design of universal wearable sensors with...
A new methodology to create 3D origami patterns out of Si nanomembranes using pre‐stretched and pre‐patterned polydimethylsiloxane substrates is reported. It is shown this approach is able to mimic paper‐based origami patterns. The combination of origami‐based microscale 3D architectures and stretchable devices will lead to a breakthrough on reconfigurable systems.
Local hypoxia in tumors, as well as the short lifetime and limited action region of 1O2, are undesirable impediments for photodynamic therapy (PDT), leading to a greatly reduced effectiveness. To overcome these adversities, a mitochondria‐targeting, H2O2‐activatable, and O2‐evolving PDT nanoplatform is developed based on FeIII‐doped two‐dimensional C3N4 nanofusiform for highly selective and efficient...
