Molecular imprinting inside dendrimers.
Synthetic hosts capable of binding porphyrins have been produced by a mixed-covalent-noncovalent imprinting process wherein a single binding site is created within cross-linked dendrimers. Two synthetic hosts were prepared, using as templates 5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin and 5,10,15,20-tetrakis(3,5-dihydroxyphenyl)porphyrin. These two templates were esterified with, respectivel...
متن کاملMolecular imprinting within hydrogels.
Hydrogels have been used primarily in the pharmaceutical field as carriers for delivery of various drugs, peptides and proteins. These systems have included stimuli-responsive gels that exhibit reversible swelling behavior and hence can show modulated release in response to external stimuli such as pH, temperature, ionic strength, electric field, or specific analyte concentration gradients. The...
متن کاملMolecular Genetics of Genomic Imprinting
Keywords Androgenetic Embryo An embryo with two paternal genomes, and no maternal genome, produced by nuclear transplantation. Chromatin DNA packaged around nucleosomes. The degree of packaging differs between active (euchromatic) and inactive (heterochromatic) chromosomal regions.
متن کاملDynamic studies of molecular imprinting polymerizations
Mechanisms of interaction of a three-dimensional polymer with solutes are of interest in the development and function of synthetic biomimetic polymers. We have investigated the effects of template/monomer interactions and template concentration on conversion and polymerization rates of a molecularly imprinted polymer. Copolymers of 2-hydroxyethyl methacrylate (HEMA) and poly(ethylene glycol) di...
متن کاملMolecular mechanisms of memory in imprinting
Converging evidence implicates the intermediate and medial mesopallium (IMM) of the domestic chick forebrain in memory for a visual imprinting stimulus. During and after imprinting training, neuronal responsiveness in the IMM to the familiar stimulus exhibits a distinct temporal profile, suggesting several memory phases. We discuss the temporal progression of learning-related biochemical change...
