An AFM cantilever is an exceptional tool for measuring friction and adhesion forces at the nanoscale. We have recently shown the possibility of fixing microscopic liquid droplets on the end of a tipless AFM cantilever, which was used to measure friction forces of a Teflon surface (D. Cortes et al., Physical Review Letters 135, 048203, 2025). In this new work, we have set out to extend this approach by fixing microscopic liquid marbles at the end of an AFM cantilever. Liquid marbles are prepared from hydrophobic nanoparticles of CaCO3. We first spray a mixture of water glycerol over a powder of these CaCO3 nanoparticles, which creates a collection of microscopic liquid marbles. Afterwards, we attach these droplets to a hydrophobic tipless AFM cantilever with a hydrophilic sticky point. With this system we explore liquid marble friction, adhesion and stability.
