(a) Confocal laser scanning micrograph of hexadecane droplets stabilized by bacterial cellulose nanocrystals (BCN) with double staining (oil stained with BODIPY564/570 and BCN stained with calcofluor white). (b,c) Scanning electron micrographs of styrene-polymerized Pickering emulsion stabilized by BCN. (d) Confocal laser scanning micrograph of citrus oil droplets stabilized by regenerated cellulose with double straining (oil stained with Nile red and cellulose shell stained with calcofluor white). (e,f) Scanning electron micrographs of styrene-polymerized emulsion stabilized by cellulose regenerated from an 85 wt% phosphoric acid solution. (g) Fluorescence microscope image of double stained cellulose-coated emulsion droplets of n-hexadecane/toluene (1/1) (oil mixture stained with Nile red and cellulose shell stained with calcofluor white). (h) Cryo-SEM image of the fractured surface of an empty cellulose-shell of an emulsion prepared from a molecular solution of cellulose in 1-ethyl-3-methylimidazolium acetate (EMIMAc).
