Fig. 7From: Use of an oxygen planar optode to assess the effect of high velocity microsprays on oxygen penetration in a human dental biofilms in-vitroDissolved oxygen profile across the HVM treated area in the Petri plate biofilm. Top panels are a time series showing the oxygen distribution represented as a color heat map. The graph below shows the DO concentration across the HVM cleared area at the various time points. The biofilm was exposed to HVM treatment at 6 days and again at 7 days. The diameter of the HVM cleared area was approximately 1 cmBack to article page
