We used periodic mesoporous silica particles for molecular imprinting. The imprinted silica particles showed fast kinetic binding for the template due to their nanosized wall thickness and high surface area.

Many efforts have been made to produce artificial materials with biomimetic properties for applications in binding assays. Among these efforts, the technique of molecular imprinting has received much attention because of the high selectivity obtainable for molecules of interest, robustness of the produced polymers, simple and short synthesis, and excellent cost efficiency. In this review, progr...

A cluster of imprinted genes on human chromosome 15q11-q13 (the PWS/AS domain) and its ortholog on mouse chromosome 7c is believed to be regulated by an imprinting control center. Although minideletions in this region in Angelman syndrome (AS) and Prader-Willi syndrome (PWS) patients revealed that two elements, shortest deletion regions of overlap in AS families and PWS families (AS-SRO and PWS...

Imprinting of cholesteric textures in a polymer network is a method of preserving a macroscopically chiral phase in a system with no molecular chirality. By modifying the elastic properties of the network, the resulting stored helical twist can be manipulated within a wide range since the imprinting efficiency depends on the balance between the elastic constants and twisting power at network fo...

Abuse and residues of antibiotics cause great harm to organisms the environment. Appropriate sample pretreatment is usually required for sensitive determination, because low content presence a variety in complicated matrices. Molecular-imprinting-based solid-phase extraction (MISPE) has been widely used antibiotics, using molecularly imprinted polymers (MIPs) as adsorbents. Herein, we comprehen...

A new interfacial nano and molecular imprinting approach is developed to prepare spherical molecularly imprinted polymers with well-controlled hierarchical structures. This method is based on Pickering emulsion polymerization using template-modified colloidal particles. The interfacial imprinting is carried out in particle-stabilized oil-in-water emulsions, where the molecular template is prese...

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.

Imprinted genes are expressed predominantly from either their paternal or their maternal allele. To date, all imprinted genes identified in plants are expressed in the endosperm. In Arabidopsis thaliana, maternal imprinting has been clearly demonstrated for the Polycomb group gene MEDEA (MEA) and for FWA. Direct repeats upstream of FWA are subject to DNA methylation. However, it is still not cl...

The determination of brominated flame retardants is of great importance, but remains a challenge. Particularly, universal and facile approaches are limited. Here we report a new general approach, combining molecular imprinting and electrospinning, for the efficient and facile imprinting sensor of 2,4,6-tribromophenol (TBP), which was used as a “novel” brominated flame retardant. With TBP as the...
