The current–voltage characteristics I(V) of model organic devices are studied under ultra-high-vacuum conditions. Active materials are N,N8-bis-(1-naphthyl)-N,N8-diphenyl1-1,1-biphenyl1-4,48-diamine ~a-NPD! and pentacene, electrode materials are polycrystalline Au and the conductive polymer poly~3,4-ethylenedioxythiophene!/poly~styrenesulfonate! ~PEDOT/ PSS!. Despite a similar work function of ...

[Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)] (PEDOT:PSS, Baytron P) composite films were prepared under various conditions and their conductivities were studied by the current-sensing atomic force microscopy (CS-AFM) technique. Topographic and current images of pristine and additive-treated PEDOT:PSS as well as electrochemically synthesized PEDOT films were obtained in nanoscale us...

This paper presents long-term stable multichannel recording of neural activity using novel intracortical floating probes implanted chronically in rat cortex. The novel flexible probe design approach allows recording of action potentials for at least 38 days after implantation. Furthermore the capability of the PEDOT: PSS coated microelectrodes for electrical stimulation is characterized in vitr...

The sensitive detection of cancer biomarkers in urine could revolutionize cancer diagnosis and treatment. Such detectors must be inexpensive, easy to interpret, and sensitive. This report describes a bioaffinity matrix of viruses integrated into PEDOT films for electrochemical sensing of prostate-specific membrane antigen (PSMA), a prostate cancer biomarker. High sensitivity to PSMA resulted fr...

Polyphenol compounds, such as caffeic acid, are important substrates of oxidation in beverages such as wine, and more rapid and sensitive methods of analysis are being sought. The conducting polymer poly-3,4-ethylenedioxythiophene (PEDOT) provides good separation of caffeic acid from antioxidant additives in wines, and produces a clear anodic peak that can be used to quantify caffeic acid and r...

Chemical warfare agents (CWA) continue to present a threat to civilian populations and military personnel in operational areas all over the world. Reliable measurements of CWAs are critical to contamination detection, avoidance, and remediation. The current deployed systems in United States and foreign militaries, as well as those in the private sector offer accurate detection of CWAs, but are ...

In this paper, we demonstrate the preparation of a flexible poly (3,4-ethylenedioxythiophene) -poly (styrenesulfonate)/reduced graphene oxide (PEDOT-PSS/RGO) film with a layered structure via a simple vacuum filtered method as a high performance electrochemical electrode. The PEDOT-PSS/RGO films are characterized by scanning electron microscopy (SEM), X-ray diffraction, Raman spectroscopy, and ...

Graft copolymers between conducting PEDOT and biodegradable PCL were synthesized investigated for 3D printing scaffolds patterning of muscle cells.

Conductive polymers are nowadays attracting great attention for their peculiar mechanical, electrical and optical proprieties. In particular, PEDOT can be used in a wide range of innovative applications, from electroluminescent devices to photovoltaics. this work, the electrochemical deposition 3,4 ethylenedioxythiophene (EDOT) was performed on various substrates (ITO, thin films gold palladium...
