Growth systems for saliva/plaque biofilms. a HA discs placed in wells of a 12 well plate with 2 mL of medium. b Dual chamber growth system. To make the chamber the glass microscope slide was replaced with a planar optode (yellowish amber) which was glued to the chambers with silicone. Two mL of medium was held in each well. c Petri plate growth system. The optode was fixed to the bottom of the Petri plate using electrical tape to prevent the seepage of medium underneath the optode. The optode was submerged under 5 mL of growth medium
