Dosing rate, not recipe, sets the batch-to-batch spread of a MnO₂ peroxidase mimic
A research poster from the School of Continuous Improvement makes 54 batches of a peroxidase-mimicking manganese oxide nanozyme in three arms of 18, with a logging balance under every receiving flask. Hand-dosed batches span a fourfold range of specific activity that a tightened recipe leaves almost unchanged (CV 31% against 29%), the first-minute permanganate arrival rate explains 71% of that variance, and syringe-pump dosing cuts the spread to a CV of 9%.
