Characterization of molecularly imprinted polymers with the Langmuir-Freundlich isotherm.
The ability of the LF isotherm to model MIPs suggests that a unimodal heterogeneous distribution is an accurate approximation of the distribution found in homogeneous and heterogeneous MIPS.
Characterization of the imprint effect and the influence of imprinting conditions on affinity, capacity, and heterogeneity in molecularly imprinted polymers using the Freundlich isotherm-affinity
The origins of the molecular imprinting effect were studied using the newly developed Freundlich isotherm-affinity distribution (FIAD) analysis and MIPs were found to have higher capacities than the corresponding nonimprinted polymers and to be more heterogeneous than NIPs.
Surface-catalyzed transformations of aqueous endosulfan.
Rates of endosulfan hydrolysis over the different surfaces corresponded to their tritium-exchange site-density and suggest a mechanism involving surface coordination prior to nucleophilic attack.
Measurement of the continuous distribution of binding sites in molecularly imprinted polymers
Reported is the first affinity spectrum (AS) [number of binding sites (N) vs. association constant (K)] for a non-covalently imprinted polymer. The AS method yields the distribution of sites over
Recognition Directed Site-Selective Chemical Modification of Molecularly Imprinted Polymers
Demonstrated is the site-selective chemical modification (SSCM) of molecularly imprinted polymers (MIPs). In this strategy, MIPs are selectively chemically modified to improve the ratio of
Steps to demarcate the effects of chromophore aggregation and planarization in poly(phenyleneethynylene)s. 1. Rotationally interrupted conjugation in the excited states of
A series of photophysical measurements and semiempirical calculations were carried out with 1,4-bis(phenylethynyl)benzene in search of evidence on the effects of phenyl group rotation and chromophore
Importance of Functional Monomer Dimerization in the Molecular Imprinting Process
We examined the influence of functional monomer dimerization on the efficiency of the molecular imprinting process. Specifically, the influence of methacrylic acid (MAA) dimerization on the binding
