Inkjet Printed Fet for Biosensing Applications
نویسندگان
چکیده
The developed bio-field effect transistor (BioFET) consists in nano-silver ink printed source and drain electrodes, a polymeric organic semiconductor, dielectric layer based on methyl methacrylate (MMA) and finally the reference electrode of silver-silver chloride ink. The thickness of the dielectric layer was optimized and characterized by Scanning Electron Microscopy (SEM) and by electrical measurements to characterize the dielectric breakdown and the semiconductor dielectric interface. The electrical characterization was also performed using different electrolytic solutions. Finally some preliminary results about the FET functionalization onto dielectric layer so as to obtain a BioFET are shown.

متن کاملWater Fast of Inkjet Print by Using Acrylic /Nano-Silver Ink
A colour ink jet printing with improved water fastness property was produced by using of special component in the ink’s formulation. In this study, the water fastness of ink jet prints which used acrylic/nano-silver resin nano-composite ink instead of conventional resin in ink’s formulation was examined. The nano composite resin was prepared via miniemulsion polymerization of acrylate monomers ...
متن کاملSolution‐Processed Vertically Stacked Complementary Organic Circuits with Inkjet‐Printed Routing
The fabrication and measurements of solution-processed vertically stacked complementary organic field-effect transistors (FETs) with a high static noise margin (SNM) are reported. In the device structure, a bottom-gate p-type organic FET (PFET) is vertically integrated on a top-gate n-type organic FET (NFET) with the gate shared in-between. A new strategy has been proposed to maximize the SNM b...
متن کاملInkjet printed flexible antenna on textile for wearable applications
We report a direct write inkjet printing technique for fabricating a flexible antenna on textile for use in smart textile applications such as wearable systems (Rienzo et al. 2006). The complete antenna was deposited entirely using inkjet printing. The inkjet printed antenna is based on a half wavelength dipole antenna offering a planar structure and acceptable size. The printable silver nanopa...
متن کاملJet-printed electrodes and semiconducting oligomers for elaboration of organic thin-film transistors
A new oligomer of bithiophene and substituted fluorene has been successfully synthesized, exhibiting good FET performance. Our results show that devices can be obtained from inkjetted OTFTs and elaborated by direct writing without any particular pre-patterning or self-alignment techniques. We have also demonstrated the possibility to fabricate inexpensive OTFTs by direct writing paving the way ...
