Innovative Two-Photon Lithography Method Sets Milestone in 3D Printing of Nanostructures.
Additive manufacturing, commonly known as 3D printing, reaches a new pinnacle with a groundbreaking method for producing Nickel Nanopillars. A research team led by Whenxin Zhang from Lund University in Sweden has introduced an innovative technique based on Two-Photon Lithography that could revolutionize the production of nanostructures.
The resulting nanopillars not only exhibit superior robustness compared to conventional methods but also open up promising applications in areas such as catalysis, photonics, and nanorobotics.
The challenges of conventional nanofabrication, such as dealloying and templated electrodeposition, are overcome by employing a laser-based lithography process—Two-Photon Absorption. This method allows for precise work with minimal impact on the surrounding material.
The process begins with the 3D printing of nanopillars in a hydrogel polymer using Two-Photon Absorption. Subsequently, the structured polymer hydrogel is immersed in a Nickel(II) nitrate solution and, after drying, burned in an oven, leaving behind only porous Nickel Nanopillars.
Tests demonstrate that these nanopillars exhibit superior stability compared to similar structures produced by traditional methods. This groundbreaking method not only promises advancements in the development of advanced materials but also opens new perspectives for innovative technologies. From improved catalysts to advanced photonic devices and revolutionary approaches in nanorobotics, the implications of this discovery are extensive and promising.
