Beilstein J. Nanotechnol. 2024, 15, 1376–1389, doi:10.3762/bjnano.15.111
- biomimetic approach to surface passivation involves a series of surface coatings based on the slick surfaces of carnivorous pitcher plants (Nepenthes), termed slippery liquid-infused porous surfaces (SLIPS) [4]. When wetted, the slippery surfaces on the plant cause prey to slide into the bottom of the
