Fig. 1: Overview of inspiration and proposed biomimetic concept.

a Natural trichomes of Drosera capensis. b Components of the sugar-based natural deep eutectic solvent used in this study. From left to right: glucose, fructose, sucrose, water, all components mixed (1:1:1:11 mole ratio), and NaDES formed after heating at the same ratio. c Schematic illustration of the proposed trichome biomimetics and trapping mechanism.
