1. A Janus particle, the Janus particle comprising (a) a single hydrophilic lobe derived from one or more natural or naturally-derived hydrophilic species; and (b) a single hydrophobic lobe derived from one or more natural or naturally-derived hydrophobic species, each of the single hydrophilic lobe and the single hydrophobic lobe having a rounded surface, and one of the single hydrophilic lobe and the single hydrophobic lobe cupped over the rounded surface of the other of the single hydrophilic lobe and the single hydrophobic lobe,
wherein the natural or naturally-derived hydrophilic species comprises a polysaccharide or a peptide, and
wherein the natural or naturally-derived hydrophobic species comprises a glyceride, a resin, or a wax.
