diode behavior and reporting lifetime comparable with literature reports for spincoated devices [25]. Moreover, microcapacitors with controlled electrical capacity
in the pF-nF range have been reported using LIFT, where micrometric-sized pixels
of hybrid organic–inorganic thin films (Ag/parylene-C) have been transferred [74].
In the same context, Rapp et al. [72], have demonstrated multilayer capacitor pixels
using picosecond LIFT along with a smart beam shaping technique that included a
double mask setup.
9.4.2 Laser Printing for Chemical Sensors and Biosensors
The ability of LIFT to transfer a wide range of materials has enabled the academic
community to investigate the printing of materials—other than metals—such as polymers [17, 18, 75–79], carbon nanotubes [80], carbon nanotube/polymer nanocomposites [81], oxides [82, 83], and biomaterials [26, 27, 46, 84–106] for the fabrication
