We present a novel technology for printing nanomaterials on a submicron scale . The XTPL approach is based on a guided assembly of nanoparticles using the dielectrophoretic attraction . The printing process is sketched in Fig. 1: The printing head deposits an ink, i.e.,nanoparticles in a liquid solution, on a non-conductive substrate, such as glass or flexible foil.Afterwards an external alternating electric field causes nanoparticles to assemble and form a line.
SEM images of example lines are shown in Fig. 2. The feature size of the printed
structures is in the range from 100 nm to 3 µm. The properties of the lines are tuned by changing
1) amplitude, shape, and frequency of the electrical signal; 2) physicochemical properties of the inks; 3) shape and size distribution of nanoparticles.There is a wide range of possible applications of the XTPL approach. One of the most promising is the fabrication of biosensors and lab-on-chip devices. In this regard, the surface of nanoparticles can be functionalized to provide both optical and electrical sensing.

Aneta Wiatrowska has been with XTPL since September 2016 and is currently holding the position of Technology Director. She is responsible for R&D department related to the printing of ultra-thin conductive lines. The team under her management – consisting of Application Laboratory, Pre-Post Laboratory, Numerical Simulation Laboratory and Advanced Characterization Laboratory – develops globally innovative technology protected by international patent applications, that has all the features of so called disruptive technology.
In the years 2013-2015 she participated in a prestigious post-PhD scholarship under the EU Marie Curie (LUMINET) project at the Philips Research Center in Eindhoven, the Netherlands,where she worked primarily on the synthesis, protection and characterization of hygroscopic lutoid iodides, Lul3 doped with lanthanum and synthesis and characterization of scintillation nanoparticles and production of polyurethane based composites containing previously synthesized scintillation nanoparticles. Earlier in 2013, she honored her doctoral dissertation
at the Faculty of Chemistry at the University of Wroclaw, where she worked for 4 years on new X-ray memories and was a contractor for 4 EU-funded research and development projects:
– Sintered Nanoceramics Scintillators – characteristic of new materials under synchrotron radiation at Superlumi Station at DESY, Germany;
– New efficient phosphors for lighting and solar concentrators;
– Detectors and converters of electromagnetic radiation for digital medical diagnosis and security;
– Innovation challenge within the area of scintillators;
She has two patent applications (PHILIPS 2014P00722EP & PHILIPS 2014P00721EP) and two patents (PCT / PL2012 / 050002,10.01.2012 and PCT / PL2014 / 050001, 18.12.2014).
XTPL is a company developing technology enabling ultra-precise printing of nanomaterials. Pioneering printing system designed by XTPL makes it possible to precisely apply to the printing surface a special ink formulated for this purpose in the company’s laboratories.
Under the influence of an external electric field nanoparticles in the ink create conductive lines according to the specified parameters. As Company Logo such, the thickness of the individual lines (even 100nm), their length and the distance between them all vary depending on a specific application. The solution will revolutionize many industry sectors i.e.printed & flexible electronics, solar cells.
