Here, we introduce a microfluidic platform in which a collagen-coated liquid–liquid interface formed between perfluorocarbon (FC-43) and culture medium serves as a substrate for epithelial cell adhesion. By culturing

Importantly, culturing cells at a liquid–liquid interface provides a unique opportunity to decouple biochemical signaling from substrate-imposed mechanical constraints, thereby enabling more physiologically relevant

Like the pitcher plant surfaces, SLIPS can repel adhesion through the formation of a liquid–liquid interface, unlike more standard surface passivation techniques that consist of a solid–liquid interface [16]. Within a SLIPS coating, a lubricant

• -octanol solution was added dropwise to the zinc nitrate solution. The mixture was kept at 80 °C in an oil bath for 12 h to form a ZIF-8 free-standing thin film on the liquid–liquid interface. After the reaction, fragments of the ZIF-8 thin film were dispersed in methanol to remove solvents and unreacted

• decreased to 2 μm when the reaction temperature increased to 120 °C (Figure 3f). The thinner membrane thickness can also be attributed to the disturbed liquid–liquid interface during synthesis. The growth of ZIF-8 crystals was also investigated regarding different reaction times. The SEM images showed that

• reaction temperature led to higher crystallinity. A further increase of the reaction temperature to 120 °C caused a decrease of the separation factor to 1.77, which was due to the unstable liquid–liquid interface under boiling. In addition, the elevated temperature increased water/1-octanol solubility and
