Query: Cost-Effective Methods to Nanopattern Thermally Stable Platforms on
  Kapton HN Flexible Films Using Inkjet Printing Technology to Produce
  Printable Nitrate Sensors, Mercury Aptasensors, Protein Sensors, and Organic
  Thin Film Transistors   Kapton HN films, adopted worldwide due to their superior thermal durability
(up to 400 {\deg}C), allow the high temperature sintering of nanoparticle based
metal inks. By carefully selecting inks and Kapton substrates, outstanding
thermal stability and anti-delaminating features are obtained in both aqueous
and organic solutions and were applied to four novel devices: a solid state ion
selective nitrate sensor, an ssDNA based mercury aptasensor, a low cost protein
sensor, and a long lasting organic thin film transistor (OTFT). Many
experimental studies on parameter combinations were conducted during the
development of the above devices. The results showed that the ion selective
nitrate sensor displayed a linear sensitivity range with a limit of detection
of 2 ppm. The mercury sensor exhibited a linear correlation between the RCT
values and the increasing concentrations of mercury. The protein printed
circuit board (PCB) sensor provided a much simpler method of protein detection.
Finally, the OTFT demonstrated a stable performance with mobility values for
the linear and saturation regimes, and the threshold voltage. These devices
have shown their value and reveal possibilities that could be pursued.
