Nepenthes pitcher plant inspired bio-polymer embedded porous surfaces for oil aquaplaning [PDF]

Scientific Reports
The Nepenthes pitcher plant has inspired surfaces employing a liquid barrier that shields the surface from contaminants. However, such liquid-infused oil-repellent surfaces employ toxic fluorocarbons or unstable polar liquids.

Inhalationally Administered Semifluorinated Alkanes (SFAs) as Drug Carriers in an Experimental Model of Acute Respiratory Distress Syndrome

Pharmaceutics, 2021
Aerosol therapy in patients suffering from acute respiratory distress syndrome (ARDS) has so far failed in improving patients’ outcomes. This might be because dependent lung areas cannot be reached by conventional aerosols.
