Device for Carrying Out a Capillary Nanoprinting Method, a Method for Carrying Out Capillary Nanoprinting Using the Device, Products Obtained According to the Method and Use of the Device

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a device and method for capillary nanoprinting, which enables the precise deposition of extremely small volumes of "ink" (such as liquids, solutions, suspensions, or melts) onto surfaces in highly ordered and dense nanostructured patterns. The device is characterized by a monolithic combination of a porous substrate and porous contact elements, allowing ink to be transported via capillary action and deposited as nanodroplets or nanowires. This method allows the formation of regular arrays of nanoscopic dots, wires or coatings with exceptional control over position, size, density, and material composition.

Use CasesContent extracted from patent full text and abstract with AI.

• Fabrication of nanoscale electronic or photonic devices by printing arrays of functional nanodots, nanowires, or coatings.
• High-density nanodroplet lithography for advanced patterning in semiconductor manufacturing.
• Creation of lab-on-a-chip diagnostic platforms for massively parallel biomolecular screenings or single-molecule analysis.
• Manufacture of membranes with highly ordered nanopores for filtration, sensing, or energy applications.
• Controlled assembly of nanoparticles or chemicals on surfaces for catalysis or sensing.
• Direct printing of nanostructured electrodes for batteries or supercapacitors.
• Generation of nanoarray sensors for environmental monitoring or medical diagnostics.

BenefitsContent extracted from patent full text and abstract with AI.

• Allows precise, parallel, and scalable deposition of extremely small droplets (femto- to attoliter), overcoming the limitations of inkjet, electrospray, and conventional lithography.
• Enables high-density patterning (over 130 features per square micrometer) over large areas.
• Flexible with the types of ink/materials, including polymers, metals, oxides, nanoparticles, and biological substances.
• Reduced material waste and improved process efficiency compared to serial techniques.
• Customization for different geometries, substrate curvatures, and operating conditions (including electrical/magnetic field modulation and temperature control).
• Enables new manufacturing techniques in nanodevices, lab-on-chip systems, and nano-lithography with higher reproducibility and resolution than previous methods.
• Compatible with both batch and roll-to-roll (continuous) production modes, aiding industrial scalability.
