Purification of synthetic oligodeoxynucleotides (ODNs) is simply achieved by capping failure sequences with a polymerizable phosphoramidite followed by polymerization. In this article, the reduction of the amount of polymerization monomer to drastically increase ODN extraction efficiency, the use of a centrifugal filterunit to ease the extraction process and the notification of using fresh phos...

Two poly(3-hexylthiophene) (P3HT) macromers containing a donor polymer with a polymerizable methacrylate (MA) end group, P3HT-CH2-MA and P3HT-(CH2)2-MA, have been synthesized, and P3HT-(CH2)2-MA has been successfully homopolymerized and copolymerized with methyl methacrylate (MMA) into stereoregular brush polymers and graft copolymers, respectively, using chiral ansa-zirconocene catalysts. Macr...

This study investigated the influence of different silica fillers on the flexural strength of experimentally filled resins. Hydrophilic (non-silanated) silica, hydrophobic silica modified by organofunctional silane, and silica modified by organofunctional silane that additionally contains polymerizable carbon double bonds were assigned into further subgroups: the first subgroup was electron bea...

Conjugated polymer/silica nanocomposites with hexagonal, cubic, or lamellar mesoscopic order were synthesized by self-assembly using polymerizable amphiphilic diacetylene molecules as both structure-directing agents and monomers. The self-assembly procedure is rapid and incorporates the organic monomers uniformly within a highly ordered, inorganic environment. By tailoring the size of the oligo...

Tubulin binding cofactor C (TBCC) is essential for the proper folding of aand b-tubulins into microtubule polymerizable heterodimers. Because microtubules are considered major targets in the treatment of breast cancer, we investigated the influence of TBCC silencing on tubulin pools, microtubule dynamics, and cell cycle distribution of breast cancer cells by developing a variant MCF7 cells with...

A novel dithiocarbamate chain transfer agent (CTA1) with a directly polymerizable Z-group was synthesized for use in reversible addition–fragmentation chain transfer polymerization (RAFT). This CTA effectively mediated RAFT polymerization of styrenic and acrylic monomers with dispersities (Đ) < 1.08. Utilizing the polymerizable Z-group on the ω-chain end that is inherited from the RAFT process,...
