Controllable Ring-Opening Polymerization in Microreactor
‹{è@^²–çE‘O“c@‰p–¾
Masaya MIYAZAKI and Hideaki MAEDA
ƒ—vŽ|„ We used a microfluidic system for polymerization of amino acid N-carboxyanhydride. The microreactor produced polymers with a narrow molecular weight distribution. Also, the Mn of the polymer produced using the microreactor was simply governed by the flow rate. These results indicated that the microreactor is a useful tool for ring-opening polymerization reactions.

ƒ—vŽ|„ Microreactor-assisted activation of titanocenes with methylaluminoxane resulted in an active homogenous polymerization catalyst for 1,3-butadiene. The micro flow system, composed of several types of microreactors, was able to promote several reaction steps like activation, initiation, propagation and termination within one process.

Akihiro ORITA and Junzo OTERA
ƒ—vŽ|„ Compaction of a multi-step organic synthesis is one of the practical technologies for the realization of effective and environmentally benign synthetic processes because the whole procedure can be carried out by using a microreactor. Herein are described the compaction of a synthetic process and the connected organic synthetic steps by use of a microreactor.

Youichi TAKIZAWA and Takanori TAKAHASHI
ƒ—vŽ|„ The twisting ball display has been known as the first developed electronic paper. However, it is extremely difficult to produce the particles suitable for this device. We succeeded in developing a new manufacturing method for Janus beads set in the twisting ball display by applying the droplet formation in microchannel technique.

Folding Manipulation for Functional Biopolymer Design
“ˆ“c@’¼•FEŠÛŽR@Œú
Naohiko SHIMADA and Atsushi MARUYAMA
ƒ—vŽ|„ Folding of biomolecules such as proteins or nucleic acids is crucial for their functions. Recently, design of functional peptides and proteins on the basis of structure prediction has been reported. Nucleic acids are also utilized to design functional materials with well-characterized nano-order structures. Novel materials that change their structures and thereby function upon external stimuli have been also reported. Riboregulators or DNA nanomachines change the structure by external stimuli such as pH change, light irradiation or addition of ligand and subsequently act as smart molecules. Chaperones are proteins that assist biopolymer folding. Artificial chaperons are designed and are applied to control protein and nucleic acid folding and functions.
