“…Among low-dimensional materials, perovskite nanocrystals have attracted particular attention in optoelectronic detection applications due to their high absorption cross section, long carrier diffusion length, and tunable optical properties. Austin et al 100 added perovskite nanocrystals at a concentration of 5 mg mL −1 to a mixed solvent of low-boiling hexane and highboiling cyclohexanone and terpineol (1:3:1 v/v) as an ink formulation for inkjet printing CsPbX 3 (X is Br or I) and used these nanocrystals as photosensitive layers in graphene photodetectors, depositing them on chemical vapor deposition-grown single-layer graphene and inkjet-printed graphene (iGr) devices. Subsequently, a fully printed CsPb(Br/I) 3 /iGr photodetector was realized by inkjet printing graphene, perovskite nanocrystals, and Au electrodes (Au nanoparticle ink), with a maximum response of 20 A W −1 .…”

Inkjet printing (IJP) as an emerging technology is expected to achieve a new generation of printable, low-cost, large-area, and high-performance perovskite optoelectronic devices. However, the coffee ring effect generated during inkjet printing and mutual solubility issues often lead to poor crystallization and uneven film thickness of printed perovskite films, thus deteriorating device performance. This mini review introduces classification and principles of IJP technology and printability of ink and then highlights several key strategies for achieving uniform high-quality perovskite films with inkjet printing. These strategies consist of developing stable ink formulations, improving substrate wettability, controlling droplet deposition, utilizing film pre- or post-treatment techniques, and so on. Finally, regarding the forefront and hotspots in the current research fields, this review summarizes the application progress of inkjet-printed perovskites in the optoelectronic fields of solar cells, lighting and display, and photodetectors and the optical fields consisting of anticounterfeiting and down-conversion films of light-emitting diodes (LEDs) or organic LEDs, and the review looks forward to the bright future of IJP technology for achieving different types of emerging perovskite optoelectronic and optical applications.

“…[21,22] Most of the reported nanomaterial-based inks are responsive to physical stimuli, such as pressure, [23][24][25] temperature, [26,27] or light. [28,29] The inks responsive to chemical stimuli are typically limited to gas, [30,31] pH, [32,33] and humidity [32,34] detection. To date, responsiveness to more complex chemical stimuli, such as clinically or environmentally relevant analytes, is typically achieved by post-functionalization of the printed devices.…”

Hundreds of new electrochemical sensors are reported in literature every year. However, only a few of them makes it to the market. Manufacturability, or rather the lack of it, is the parameter that dictates if new sensing technologies will remain forever in the laboratory in which they are conceived. Inkjet printing is a low‐cost and versatile technique that can facilitate the transfer of nanomaterial‐based sensors to the market. Herein, an electroactive and self‐assembling inkjet‐printable ink based on protein‐nanomaterial composites and exfoliated graphene is reported. The consensus tetratricopeptide proteins (CTPRs), used to formulate this ink, are engineered to template and coordinate electroactive metallic nanoclusters (NCs), and to self‐assemble upon drying, forming stable films. The authors demonstrate that, by incorporating graphene in the ink formulation, it is possible to dramatically improve the electrocatalytic properties of the ink, obtaining an efficient hybrid material for hydrogen peroxide (H2O2) detection. Using this bio‐ink, the authors manufactured disposable and environmentally sustainable electrochemical paper‐based analytical devices (ePADs) to detect H2O2, outperforming commercial screen‐printed platforms. Furthermore, it is demonstrated that oxidoreductase enzymes can be included in the formulation, to fully inkjet‐print enzymatic amperometric biosensors ready to use.
