Advanced Materials, EarlyView.Inspired by mussel proteins, YDC‐Gel‐Zn is a smart bone glue designed for osteoporotic implants. It adheres strongly to both metal implants and bone for initial fixation. In osteoporosis's inflammatory environment, it sequentially releases zinc ions and therapeutic peptides: the zinc modulates immune cells to reduce inflammation, while the peptides ...

Engineering Aging: Approaches to Model and Deconstruct Biological Complexity
Advanced Materials, EarlyView.The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

Advanced Materials Technologies, EarlyView.Hydrogel‐forming microneedle patches are developed using shape‐preserving PVA‐PVP hydrogels, with and without chitosan, for minimally invasive transdermal protein biomarker sampling. The optimised patches enable efficient interstitial fluid uptake and proteomic analysis, while minimising interference.
