“…The resulting high-speed particle stream remained focused over a distance of 2 mm from the nozzle to the substrate without compromising the resolution. Once the chip was fabricated, photonic curing was used to rapidly and efficiently convert the graphene ink solution into high-quality thin-film electrodes . Samples were passed through a Novacentrix Pulseforge 3300 machine to expose graphene to the incident energy.…”

An aerosol jet printing-enabled dual-function biosensor for the sensitive detection of pathogens using SARS-CoV-2 RNA as an example has been developed. A CRISPR-Cas13:guide-RNA complex is activated in the presence of a target RNA, leading to the collateral trans-cleavage of ssRNA probes that contain a horseradish peroxidase (HRP) tag. This, in turn, catalyzes the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) by HRP, resulting in a color change and electrochemical signal change. The colorimetric and electrochemical sensing protocol does not require complicated target amplification and probe immobilization and exhibits a detection sensitivity in the femtomolar range. Additionally, our biosensor demonstrates a wide dynamic range of 5 orders of magnitude. This low-cost aerosol inkjet printing technique allows for an amplification-free and integrated dual-function biosensor platform, which operates at physiological temperature and is designed for simple, rapid, and accurate point-of-care (POC) diagnostics in either low-resource settings or hospitals.

“…Therefore, in our present work, we intended to use indium-free pure ZnO as the semiconductor in order to reduce the cost of the device and demonstrate the mechanical flexibility and optical transparency of the device. In addition, unlike most of the previous works in which only the semiconducting layers were photonic cured, in our work, the ZrO 2 -based gate insulating layer was also obtained by photonic curing. , This not only reduced the operating voltage and improved the device performance but also enabled us to fabricate the devices on a flexible substrate at a significantly lower cost and save important processing time. Therefore, it can be stated that for devices such as TFTs in which multiple layers are used and all the layers can be made of MOs, this work can be treated as a stepping stone toward realizing all photonic cured, low-voltage, high-performance, flexible, and transparent TFTs opening the door for commercial production of next-generation flexible and transparent electronics.…”

Flash light-based photonic curing has recently emerged as a promising technique for low-cost and ultrafast production of flexible electronics. In this work, we demonstrate photonic curing-based low-cost fabrication of ZrO 2based high-k dielectric and ZnO-based semiconducting layers for low-voltage, high-performance, flexible, and transparent thin-film transistors (TFTs). Such metal oxide-based devices are extremely important to realize next-generation technologies with high power efficiency, optical transparency,mecahnical flexibility, high reliability, and environmental stability. In the current work, photonic cured ZrO 2 and ZnO layers were obtained by exposing their spin-coated precursor solutions to the high-energy pulsed light of a xenon flash lamp. The numbers of applied pulses were varied for optimization. Hence, the optimally cured ZrO 2 film exhibited excellent dielectric property with high areal capacitance of ∼485 nFcm −2 , low leakage current density of 10 −4 A cm −2 , and high breakdown strength of ∼2.3 MV cm −1 which further enabled the low-voltage operation (< 3 V) for the fabricated TFTs. On the other hand, the optimally cured ZnO layer resulted in the high performance for the TFTs with field-effect mobility of 3.4 ± 0.1 cm 2 V −1 s −1 , on−off ratio of 3.3 ± 0.8 × 10 5 , and threshold voltage of 0.8 ± 0.03 V. The mechanical flexibility of these devices was demonstrated by showing their operational stability under mechancial bending and after continuous bending cycles. These devices also exhibited optical transparency up to 80% in the visible wavelength range. To explain the behavior of these photonic cured layers and devices under different process conditions, several microscopic and spectroscopic studies were performed. Finally, the ultraviolet−visible absorption spectroscopy and a finite element simulation study also showed the viability of photonic curing to successfully fabricate solution-derived ZnO and ZrO 2 layers on a flexible substrate.
