Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

open access: yesAdvanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...
