“…[36] The resulting graphene screen printing paste has shown high printing definition and good conductive properties. To investigate the influence of post-processing methods on the morphology and conductive properties of the graphene conductors, a line was stencil printed (Figure 1a) across resistivity/temperature probes [33] (Figure 1b). Details on the setup and it is operating principle can be found in Abbel et al [33] Here, stencil printing is used as a simplified version of screen printing enabling fast sample preparation with fair printing definition.…”

“…These methods include Joule heating, [31] microwave irradiation, [12] infra-red heating, [32] and photonic flash annealing. [6,[33][34][35] The latter is a contactless, highly controllable method compatible with highspeed R2R processing and, since it is based on the light absorption, holds great promise for graphene applications.…”

This paper describes a combination of photonic annealing and compression rolling to improve the conductive properties of printed binder‐based graphene inks. High‐density light pulses result in temperatures up to 500 °C that along with a decrease of resistivity lead to layer expansion. The structural integrity of the printed layers is restored using compression rolling resulting in smooth, dense, and highly conductive graphene films. The layers exhibit a sheet resistance of less than 1.4 Ω □−1 normalized to 25 µm thickness. The proposed approach can potentially be used in a roll‐to‐roll manner with common substrates, such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and paper, paving thereby the road toward high‐volume graphene‐printed electronics.

“…The silver nanoparticle (NP) ink was converted into conductive and well-adhered traces within fractions of a second by the photonic flash sintering. The principle of this technique is the selective heating of the Ag nanoparticles by the absorption of the emitted light for which the substrate is transparent [56,57]. Just after, CNT patterns that only slightly overlapped with Ag for the electrical connection were printed forming the CNT working and counter electrodes (Step II).…”

Herein, we present the large-scale fabrication of multiplexed three-electrode sensors used in a point-of-care device platform that couples a magnetic bead-based immunoassay strategy with amperometric detection for rapid and highly sensitive analysis. The multiplexed sensors consisted of eight independent electrochemical cells, each with a carbon nanotube (CNT) working electrode, CNT counter electrode and a silver-silver chloride quasi-reference electrode. The microchips were fabricated on flexible polyethylene terephthalate (PET) sheets by sequential multilayer inkjet printing (IJP) of silver, CNT and insulator inks that were either simultaneously or subsequently post-processed (e.g. through UV photo-polymerization or photonic curing). Finally, plastic wells were mounted on top of the inkjet-printed patterns to obtain an eight-well microtiter plate where each well had a solution capacity of 50 μL. Due to the high precision of the IJP process, the microtiter plates showed high reproducibility among the individual electrochemical cells (1-2% of deviation). Furthermore, the microchips can be reusable for at least up to 20 times as demonstrated herein. In a customized multichannel potentiostat with eight implemented magnets matching the positions of the working electrodes, the electrochemical readout of magnetic bead based sandwich and competitive immunoassays was successfully realized for the detection of thyroid-stimulating hormone (TSH) and atrazine (ATR) in aqueous and urine samples, respectively. The achieved limits of detection for ATR (i.e. 0.01 μg/L) and TSH (i.e. 0.5 μIU/mL) demonstrated the potential of the IJP microtiter plates for the environmental and biological quantification of analytes in a very reliable high throughput platform. This work shows that IJP has certainly reached the status of a batch production tool for electroanalytical sensing platforms.
