Contributions of lunate cells and wax crystals to the surface anisotropy of Nepenthes slippery zone.

ABSTRACT: Nepenthes slippery zone presents surface anisotropy depending on its specialized structures. Herein, via macro-micro-nano scaled experiments, we analysed the contributions of lunate cells and wax crystals to this anisotropy. Macroscopic climbing of insects showed large displacements (triple body length within 3 s) and high velocities (6.16-20.47 mm s^-1) in the inverted-fixed (towards digestive zone) slippery zone, but failed to climb forward in the normal-fixed (towards peristome) one. Friction force of insect claws sliding across inverted-fixed lunate cells was about 2.4 times of that sliding across the normal-fixed ones, whereas showed unobvious differences (1.06-1.11 times) between the inverted- and normal-fixed wax crystals. Innovative results from atomic force micros
