Nanofabrication Techniques

Two-photon polymerization is a technique that allows for the creation of complex 3D structures using focused laser beams to induce polymerization of monomers. This method offers precise control over material properties and resolution.

Focused ion/electron beam induced deposition (FIBID) involves using a focused ion or electron beam to remove material from a substrate, allowing for the deposition of thin films or nanoparticles onto its surface. This technique is particularly useful for creating nanoscale structures with high precision.

DNA origami and hierarchical self-assembly are methods that utilize DNA molecules as templates to create complex 3D shapes through controlled folding and assembly processes. These techniques leverage the unique properties of DNA to build intricate nanostructures.

Nanofabrication - Characterization Techniques

Scanning Electron Microscopy (SEM) provides high-resolution images of the fabricated structures, revealing details about their morphology and surface features. Transmission Electron Microscopy (TEM) allows for even greater magnification, enabling the observation of nanoscale features and internal structure.

3D tomography is used to measure the dimensions and volume of the fabricated components with high accuracy. Optical methods, such as laser scanning microscopy, are employed for rapid characterization of the structures' geometry and surface characteristics.

Nanofabrication for Advanced Materials

The fabrication of nanoscale structures using self-assembly techniques offers a route to create materials with tailored properties.

Precise control over material composition and microstructure at the nanometer scale is essential for achieving desired functionalities in advanced materials.

Advanced nanofabrication methods, such as focused ion beam milling and electron beam lithography, are employed to generate complex 3D structures with high precision.
