This audiobook walks through the full mathematical path behind an enzyme-based removal cartridge, in plain language and without heavy formulas. Chapters: Defining the Problem: the three numbers every removal device depends on, and choosing between free and immobilized enzymes Enzyme Kinetics Fundamentals: Michaelis-Menten saturation, helper molecules like ATP, cofactor regeneration and feedback inhibition Reaction-Diffusion in Immobilized Systems: the Thiele modulus idea, the effectiveness factor, and why bead size and porosity matter Scaffold, Reactor and Flow Design: channel geometry, pressure drop, and total coated wall area System-Level Modelling: batch vs continuous operation in a real room or shed, and designing for the worst realistic case Validation, Sensitivity and Design Workflow: finding which parameters matter, what limits your design, and how to tell whether a model can be trusted It’s useful for iGEM teams, bioprocess students and anyone getting into biochemical modelling. The specific numbers change from project to project, but the method stays the same.
