Quantum Mechanics and Molecular Dynamics Simulations
QM/MM simulation of polymer imprinting process
Tri-O-acetiladenosine molecule with five attached monomers of metacrylic acid.
Computer technologies and existing simulation methods make it possible to reduce the research costs for selecting imprinting parameters and estimate their optimal magnitudes in terms of such physicochemical criteria as template-monomer bond energy both in vacuum and solution, geometry and topology of the spatial structure of the pre-polymerization complex and the imprinted polymer, and their temperature dependencies.
The optimized geometrical structure and energy of the pre- polymerization complexes of tri-O-acetyladenosine (template) with three different monomers—methacrylic ac- id, 3-vinyl benzoic acid and acrylamide in vacuum were calculated using hybrid quantum mechanical/molecular me- chanical (QM/MM) approach.
