Synthesis of ester-siloxane multiblock copolymers

DNA multiblock copolymers.

Single stranded (ss) DNA block copolymers were applied to synthesize DNA multiblock architectures by hybridization; these polymeric bioorganic hybrids were characterized by gel electrophoresis and MALDI-TOF mass spectrometry.

Siloxane Copolymers for Nanoimprint Lithography**

Nanoimprint lithography (NIL) is a fabrication technology that offers high-throughput, ultrahigh resolution patterning at great cost savings compared to most competing next-generation radiative lithography methods. As a result of its rapid development in the past decade and its potential for sub-100 nm lithography, NIL has been listed by MIT’s Technology Review as one of ten emerging technologi...

Phase behavior of symmetric linear multiblock copolymers

Molecular-dynamics simulations are used to study the phase behavior of a single linear multiblock copolymer with blocks of Aand B-type monomers under poor solvent conditions, varying the block length N , number of blocks n, and the solvent quality (by variation of the temperature T ). The fraction f of A-type monomers is kept constant and equal to 0.5, and always the lengths of A and B blocks a...

Biodegradable Multiblock Copolymers for Drug Delivery Applications

Microspheres of a hydrophobic and a hydrophilic poly(ether-ester) copolymer were evaluated for their in-vitro and in-vivo biocompatibility and degradation. The microspheres prior to and after sterilization were tested for in-vitro cytotoxicity. The invivo biocompatibility of the poly(ethylene glycol) terephthalate and poly(butylene terephthalate) (PEGT/PBT) microspheres was evaluated subcutaneo...
