Surfactants are commonly utilized with microspheres composed of hydrophobic polymer matrices such as polystyrene to facilitate bead wetting and to deter or treat aggregation. Common concentrations are ~0.1% for uncoated polymer beads and ~0.01% in the storage buffer of coated polymer, magnetic, and silica beads.
Triton® X-100 and Tween® 20 are nonionic surfactants used in the storage buffers of coated bead suspensions, while Sodium Dodecyl Sulfate (SDS) is an anionic surfactant that decreases hydrophobicity and participates in charge stabilization of the suspension.
