Liquid marbles are liquid droplets stabilized by solid particles adsorbed to the gas-liquid interface. Theliquid marble technology makes it possible to treat the liquid as a non-sticky powder. In nature, certain kindof aphids, small sap-sucking insects, fabricate liquid marbles utilizing honeydew as an inner liquid and waxparticles as a stabilizer, and treat the sticky liquid as non-wetting materials. Recently, we developed pressuresensitiveadhesive powder consisting of liquid marbles with an adhesive polymer core and a hard nanoparticleshell morphology based on the liquid marble engineering. The pressure-sensitive adhesive powder showsno adhesion in its original form, and shows its adhesive nature only after application of shear stress. In thisreview article, we introduce liquid marbles fabricated by aphids. Then, we describe fabrication, structure andadhesive property of the pressure-sensitive adhesive powder.
