We present here an electrochemical sensor microsystem for the monitoring of pH. The all-polymeric device is comprised of a cyclic olefin copolymer substrate, a 200 nm-thin patterned layer of conductive polymer (PEDOT), and a 70 nm electropolymerized layer of a pH sensitive conductive polymer (polyaniline). The patterning of the fluidic (microfluidic channels) and conductive (wiring and electrod...

The novelty of this paper lies in the development of a multistep process for the manufacturing of plasma millireactors operating at atmospheric pressure. The fabrication process relies on the integration of metallic electrodes over a cyclic olefin copolymer chip by a combination of photopatterning and sputtering. The developed plasma millireactors were successfully tested by creating air discha...

Olefin metathesis polymerization, in particularly ring-opening metathesis polymerization (ROMP), has been a popular topic of modern research. Two other types are acyclic diene metathesis polymerization (ADMET) and cyclopolymerization of diynes. To date, there has been no report on a metathesis polymerization utilizing more than one metathesis process. Herein, the concept of multiple olefin meta...

Cyclic olefin copolymer (COC) is a novel type of thermoplastic polymer gaining the attention scientific community in electronic, optoelectronic, biomedicine and packaging applications. Despite benefits use COC such as undoubted optical transparency, chemical stability, good water–vapor barrier biocompatibility, its original hydrophobicity restricts wider applicability optimization performances....

We report the use of a terahertz (THz) transparent material, cyclic olefin copolymer (COC or TOPAS), for fabricating hollow-core antiresonant fiber that provides an electromagnetic wave guidance in THz regime. A novel fabrication technique to realize polymer optical (HC-ARPF) is proposed and demonstrated. The directly extruded single-step procedure using conventional fused deposition modeling 3...
