Inkjet printing is an excellent printing technique and an attractive alternative to conventional technologies for the production of flexible, low-cost microelectronic devices. Among many parameters that have a significant impact on the correctness of the printing process, the most important is ink viscosity. During the printing process, the ink is influenced by different strains and forces, which significantly change the printing results. The authors present a model and calculations referring to the shear rate of ink in an inkjet printer nozzle. Supporting experiments were conducted, proving the model assumptions for two different ink formulations: initial ink and with the addition of a dispersing agent. The most important findings are summarized by the process window regime of parameters, which is much broader for the inks with a dispersing agent. Such inks exhibit preferable viscosity, better print-ability, and higher path quality with lower resistivity. Presented results allow stating that proper, stable graphene inks adjusted for inkjet technique rheology must contain modifiers such as dispersing agents to be effectively printed.

A comparison study on deposition temperature between 40oC and 60oC using new route coating which is inkjet printing technique have been studied in this research paper. The FTO material were prepared by a common mixture technique between precursor solution of SnCl4.5H2O and NH4F as a doping agent. The prepared samples were coated on the glass substrate sized 20mm x 25mm and were calcined at 450oC. The samples were characterized using XRD, XPS, VP-SEM and UV-VIS. From the VP-SEM, the result show the different surface morphology between the two deposition temperatures. Samples prepared at 60oC shows a lot existence some kind of crystal shape on the substrate compared to films deposited at 40oC. Surface studies using XPS technique shows the existence of elements such as Sn, O and F. Detail analysis of these elements shows that Sn 3d5/2 form as Sn-O, O1s as oxygen linkage and F1s as Sn-F. The XPS and XRD results also shows that no significant changes on chemical stoichiometry for both deposition temperatures. The optimum optical properties with lower resistivity were found for thin films deposited at 40oC with 91 %T and 16 Ω/□.

All-printed electronics as a mean of fast processing and achieving ultra-low-cost electronic devices has attracted great interest in recent years. Inkjet printing has excelled as the most promising technique by which the circuit components can be directly drawn on the specific area in one step. Furthermore, the low temperature reduction processes can be achieved by exploit the low-melting point characteristic of nanometallic particles. The inkjet printing technique to deposit silver nanoparticles (3.39±1.21 nm) capped by saturated 3-Mercaptopropionic acid onto silicon substrate was studied. The silver patterns were tested for its functionality as circuit components like conductor, resistor and capacitor. All components can be produced simply by thermal annealing of an inkjet printed patterns under an atmosphere of 90% N2-10% H2 at 300°C for 1 hr.

Fluorine doped tin oxide (FTO) thin films have been developed as alternatives to ITO for thin film transparent electrode applications. In this works, the FTO thin films were deposited using inkjet printing technique since the technique is a promising deposition method to fabricate low-cost devices. The FTO precursor was prepared by reacting SnCl4•5H2O and NH4F at 60oC in a sealed container. The thin films were deposited on glass substrates at 40oC with variations of printing layers. The optical and electrical properties of the films were affected by the number of printed layers. It was observed the four layers film has the optimum optical transmittance and sheet resistance which were 96 %T and 16.4 Ω/□ respectively.

Abstract Recently, the three-dimensional (3D) printing technique has attracted much attention for creating objects of arbitrary shape and manufacturing. For the first time, in this work, we present the fabrication of an inkjet printed low-cost 3D temperature sensor on a 3D-shaped thermoplastic substrate suitable for packaging, flexible electronics, and other printed applications. The design, fabrication, and testing of a 3D printed temperature sensor are presented. The sensor pattern is designed using a computer-aided design program and fabricated by drop-on-demand inkjet printing using a magnetostrictive inkjet printhead at room temperature. The sensor pattern is printed using commercially available conductive silver nanoparticle ink. A moving speed of 90 mm/min is chosen to print the sensor pattern. The inkjet printed temperature sensor is demonstrated, and it is characterized by good electrical properties, exhibiting good sensitivity and linearity. The results indicate that 3D inkjet printing technology may have great potential for applications in sensor fabrication.

Abstract Background HIV remains one of the most important health issues worldwide, with almost 40 million people living with HIV. Although patients develop antibodies against the virus, its high mutation rate allows evasion of immune responses. Some patients, however, produce antibodies that are able to bind to, and neutralise different strains of HIV. One such ‘broadly neutralising’ antibody is ‘N6’. Identified in 2016, N6 can neutralise 98% of HIV-1 isolates with a median IC50 of 0.066 µg/mL. This neutralisation breadth makes N6 a very promising therapeutic candidate. Results N6 was expressed in a glycoengineered line of N. benthamiana plants (pN6) and compared to the mammalian cell-expressed equivalent (mN6). Expression at 49 mg/kg (fresh leaf tissue) was achieved in plants, although extraction and purification are more challenging than for most plant-expressed antibodies. N-glycoanalysis demonstrated the absence of xylosylation and a reduction in α(1,3)-fucosylation that are typically found in plant glycoproteins. The N6 light chain contains a potential N-glycosylation site, which was modified and displayed more α(1,3)-fucose than the heavy chain. The binding kinetics of pN6 and mN6, measured by surface plasmon resonance, were similar for HIV gp120. pN6 had a tenfold higher affinity for FcγRIIIa, which was reflected in an antibody-dependent cellular cytotoxicity assay, where pN6 induced a more potent response from effector cells than that of mN6. pN6 demonstrated the same potency and breadth of neutralisation as mN6, against a panel of HIV strains. Conclusions The successful expression of N6 in tobacco supports the prospect of developing a low-cost, low-tech production platform for a monoclonal antibody cocktail to control HIV in low-to middle income countries.

Collagen is a major component of the extracellular matrix (ECM) that modulates cell adhesion, growth, and migration, and has been utilised in tissue engineering applications. However, the common terrestrial sources of collagen carry the risk of zoonotic disease transmission and there are religious barriers to the use of bovine and porcine products in many cultures. Marine based collagens offer an attractive alternative and have so far been under-utilized for use as biomaterials for tissue engineering. Marine collagen can be extracted from fish waste products, therefore industry by-products offer an economical and environmentally sustainable source of collagen. In a handful of studies, marine collagen has successfully been methacrylated to form collagen methacrylate (ColMA). Our work included the extraction, characterization and methacrylation of Red Snapper collagen, optimisation of conditions for neural cell seeding and encapsulation using the unmodified collagen, thermally cross-linked, and the methacrylated collagen with UV-induced cross-linking. Finally, the 3D co-axial printing of neural and skeletal muscle cell cultures as a model for neuromuscular junction (NMJ) formation was investigated. Overall, the results of this study show great potential for a novel NMJ in vitro 3D bioprinted model that, with further development, could provide a low-cost, customizable, scalable and quick-to-print platform for drug screening and to study neuromuscular junction physiology and pathogenesis.
