Damage Microenvironment Guided Responsive Smart Hydrogel Design for Self‐Regenerative Repair in Chronic Wound Healing

Advanced Materials Interfaces, EarlyView.
Chronic wounds remain a major therapeutic challenge, with VEGF applications hindered by rapid degradation and systemic side effects. Here, a dual‐responsive chitosan–gelatin hydrogel is reported, functionalized with dopamine, glutathione, and MMP‐sensitive motifs, enabling spatiotemporally controlled VEGF release and enhanced biocompatibility, thereby ...

Smart Sampling Capsule for Capture and Detection of Enteric Pathogens in the Small Intestine

Advanced Materials Technologies, EarlyView.
An ingestible smart sampling capsule for capturing asymptomatic enteric pathogens at their primary sites of interaction within the small intestine. This capability enables non‐invasive detection of early pathogen colonization within the gut environment prior to fecal shedding, providing a robust approach for pathogen surveillance and microbiome studies.
