Abstract: A novel protocol for use of molecularly imprinted polymer (MIP) in analysis of melamine is presented. Design of polymer for melamine has been achieved using a combination of computational techniques and laboratory trials, the former greatly reducing the duration of the latter. The compatibility and concerted effect of monomers and solvents were also investigated and discussed. Two novel open source tools were presented which are: the online polymer calculator from mipdatabase.com and the application of the Gromacs modelling suite to determine the ideal stoichiometric ratio between template and functional monomer. The MIP binding was characterised for several structural analogues at 1-100 μM concentrations. The use of DVB as cross-linking polymer and itaconic acid as functional monomer allowed synthesis of MIP with imprint factor for melamine IF=2.25. This polymer was used in HPLC for the rapid detection of melamine in spiked milk samples with an experimental run taking 7-8 minutes. This approach demonstrated the power of virtual tools in accelerated design of MIPs for practical applications.
