Time kill curves of UPG and 5 mol % cobalt-, zinc-, and copper oxide-doped phosphate glass powders (5 mg/mL), in comparison to the untreated control, alone, and in combination against C. albicans. The combinations investigated were Co + Cu, Co + Zn, and Cu + Zn. Microbial viability is presented as log cfu/mL. Data shown are expressed as mean ± SD (N = 3).
