Pair Potential of Charged Colloidal Stars
Pair Potential of Charged Colloidal Stars
We report on the construction of colloidal stars: $1\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$ polystyrene beads grafted with a dense brush of $1\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$ long and 10 nm wide charged semiflexible filamentous viruses. The pair interaction potentials of colloidal stars are measured using an experimental implementation of umbrella sampling, a technique originally …
