DRY LAB

Introduction

Introduction

Mathematical modelling and analysis techniques were used throughout the project to gain a better understanding of the events occurring and to inform lab based decision making. Models were created for each of the aspects of the project; aging of fingerprints, the BioSpray and the chromate sensor.

BioSpray

The models for the BioSpray all follow a similar methodology. The law of mass action allows the description of chemical schematics or reaction pathways by equations. Ordinary differential equations (ODEs) were used to describe the binding reactions between the molecules in the BioSpray with their targets in the sample. Each ODE has one independent variable and its derivatives, describing the change of the variable over time. This allows for the investigation of the concentrations of substances left after binding has occurred, allowing for the analysis of the optimum concentration required in the BioSpray.
