The calibration curve of the relationship between bacterial concentration and OD values were constructed using linear regression. PMMA-CNCs-Ag and bacteria were co-cultured for 24 h, followed by the measurement of the OD value of the bacterial solutions. The corresponding bacterial concentration was ...
