    Behaviour of uniformly dimpled colloidal particles by Ivell, S

    Published 2014
    “…Finally, the depletion induced force between lock and key particles at contact is directly measured using optical tweezers. The dependence of the force due to depletion upon the overlap volume between the particles is illustrated, and we find that the strongest force is produced when the key is held within the cavity of the dimpled lock, demonstrating semiquantitative agreement with theoretical predictions.…”

    Ice rule breakdown and frustrated antiferrotoroidicity in an artificial colloidal Cairo ice by Carolina Rodríguez-Gallo, Antonio Ortiz-Ambriz, Cristiano Nisoli, Pietro Tierno

    Published 2023-01-01
    “…We realize this particle ice by confining field tunable paramagnetic colloidal particles within a lattice of topographic double wells at a one to one filling using optical tweezers. By raising the interaction strength via an applied magnetic field, we find that the ice rule breaks down, and positive monopoles with charge $q = +2$ accumulate in the z  = 4 vertices and are screened by negative ones ( $q = -1$ ) in the z  = 3. …”
