1. A cell mimic composition, comprising;
a) a population of polymer particles; and
b) an aqueous solution;
wherein the polymer particles are suspended in the aqueous solution; and
wherein, the polymer particles exhibit an optical-scatter property that is substantially similar to a corresponding optical-scatter property of a natural biological cell counterpart.
