A schematic diagram of the optical sorting system described by MacDonald et al. [140]. Chamber A contains buffer solution. Chamber B holds mixed particles. After passing through the optical lattice, selected particles are deflected into chamber C, while other particles flow straight into chamber D. The optimum lattice for fractionation was a body-centered tetragonal (b.c.t.) lattice. FC denotes the fractionation chamber
