Nanoparticles obtained from the sundew adhesive. (a) AFM images of the nanofibres and the nanoparticles obtained in sundew adhesive. Left panel, external tensile force was applied on the sundew adhesive prior to the AFM measurements. Size for the left image is 20 × 20 µm and the scale bar for the right image represents 2 µm. (b,c) Mean size and zeta potential of the obtained nanoparticles characterized by DLS and ELS, respectively. The average size for the obtained nanoparticles was 231.9 ± 14.8 nm in diameter and the zeta potential was −23.9 ± 1.7 mV. (Online version in colour.)
