A Protocol for the Computational Design of High Affinity Molecularly Imprinted Polymer Synthetic Receptors
Journal Title: Global Journal of Biotechnology and Biomaterial Science - Year 2017, Vol 3, Issue 1
Abstract
Molecularly imprinted polymer (MIP) nanoparticles, commonly referred to as ‘plastic antibodies’ or synthetic receptors, are polymeric materials with strong affinity and selectivity for a particular chemical target. MIPs are regularly produced for use in sensors for monitoring food quality and environmental pollutants, and in the design of robust and affordable replacements for biological receptors, enzymes and antibodies in drug testing and assays. More recently the easy production of MIP nanoparticles has also permitted research relating to possible in vivo applications, primarily in drug delivery systems, toxin sequestration and pathogen inhibition. The strength of the interaction between the target and the polymer binding site is dependent on the particular monomers selected in synthesis of the MIP, and the relative concentrations of these in the pre-polymerization mixture. While computational approaches have been used to aid in MIP design previously, the methods adopted are often slow and simplistic, centring on observations of the template structure with a couple of functional monomers presumed to be appropriate. We present here an automated method of rapidly screening numerous functional monomers and effectively determining appropriate monomer ratios, while accounting for spatial discrimination in selection and dynamic parameters in optimization. Example are then given of effect MIP synthesis resulting from the protocol, and the benefits of this approach over competing methods are discussed.
