Advanced Healthcare Materials, EarlyView.A water‐activated phospholipid phase‐separation gel is repurposed as a drug‐free surgical barrier for postoperative adhesion prevention. Propylene glycol promotes rapid lamellar gel reinforcement, prolonged local retention, and tissue coverage, while phosphatidylcholine‐mediated immunomodulation suppresses inflammatory and fibrotic responses. This dual‐

Biomimetic water-based lubrication: an exploration into vesicle lubrication
, 2023 The replacement of oil-based lubricants with water-based lubricants has been a desirable yet unrealised ambition in Tribology. The use of bio-lubricants has been previously explored; however limited advances have been achieved. Most work has focused on traditional mechanisms, with biomolecules being used to form friction reducing surface films. However,
