Hyperbranched polymers and Haag type dendrimers for the molecular imprinting of polymers
A molecularly imprinted polymer was synthesized using both hyperbranched polyglycerol and Haag type polyether dendrons with estradiol as a core. The attachment of the polyether dendron created a dendrimer that had 64 allyl groups available for crosslinking. Completion of the crosslinking of the …

Novel Building Blocks for Molecular Imprinting: Pyridine-Based Binding Monomers and Bio-Renewable Cross-Linkers
Molecular imprinting refers to the creation of synthetic materials with built-in memory for a selected target (atom, ion, molecule, complex or a molecular, ionic or macromolecular assembly, including micro-organisms) used as a template to direct the synthesis of the material, a Molecularly …

Integrating nanostructured artificial receptors with whispering gallery mode optical microresonators via inorganic molecular imprinting techniques
… Fortunately, biomimetic chemistries, such as molecular imprinting, allow for the design of artificial receptors with very high selectivity for the target. Here, we perform a proof-of-concept study to show how artificial receptors may be created from inorganic silanes using the molecular …

Synthesis of Organic and Water Soluble Cored Dendrimers With Internal Cross -Links
"Dendrimers also have been shown to behave as unimolecular micelles and nanocontainers. However, the capacity of the dendrimers for guest solubilization is limited. Thus, the generatinn of novel, water soluble dendrimers as potential nanocontainers with larger capacities is desired. It was hoped …
