  1. Note: Values were experimentally determined. Errors represent standard deviation. Methodology can be found in the additional files. Sulfamethazine data was performed using method 1 and tylosin data with method 2. Sulfamethazine batch experiments were performed with concentrations of 1, 3, 5, 10, 20, 30, 50, 100, and 300 ng/mL, and tylosin batch experiments were performed with concentrations of 1, 5, 10, 100, 200, 500, and ng/mL.
