Understanding interfacial slip in nanogaps is crucial for modeling fluid flow mechanical and analytical systems. To quantify length shear stress at the liquid–solid interface, we measured velocity of squeeze as was pressed between solid surfaces. Our results showed that varied with lateral positions gap heights, while had a noticeable threshold beyond which begins, indicating limiting model nanogaps. These insights enhance our understanding phenomena provide foundation their influence on flow.
