MImM

MImM is an acronym that can refer to several concepts depending on the context. In scientific literature, it most commonly denotes molecularly imprinted membranes, a class of polymeric membranes that incorporate specific molecular recognition sites designed for target molecules.

Molecular imprinting creates these recognition cavities by polymerizing functional monomers in the presence of a template molecule, followed by removal of the template. The resulting cavities are complementary in size, shape, and functional groups to the target. When integrated into a membrane, these sites enable selective permeation or binding of the target, facilitating separation, sensing, or catalysis.

Applications of molecularly imprinted membranes include selective separation of pharmaceutical compounds and environmental contaminants, chiral separations, and sensing or detection of specific analytes. They are also used in sample preparation for analytical chemistry. Variants of MImMs include surface-imprinted membranes and composite membranes that incorporate inorganic nanoparticles or conducting polymers to improve stability, selectivity, and mechanical properties.

Advantages of MImMs include high selectivity, the ability to tailor recognition properties for specific targets, and good chemical and thermal stability. Limitations can include template leakage, non-specific binding, and slower mass transfer compared with non-imprinted membranes. Research efforts aim to mitigate these issues through approaches such as surface imprinting, nanoengineering, and multi-template imprinting, as well as integration with other membrane technologies.

Because MImM can stand for different concepts in other domains, readers should verify the intended meaning from the source context.
