2-photon lithography

{
  "id": "MLC-T-CHM-000014",
  "term": "2-photon lithography",
  "field": "Chemistry",
  "definition": "A high-resolution additive manufacturing technique that uses a focused femtosecond laser to induce a two-photon absorption process in a photoresist. This localized absorption initiates polymerization only at the focal point, allowing for the creation of complex three-dimensional micro- and nanostructures. The technique achieves resolutions below the diffraction limit of light, typically in the range of 100 to 200 nanometers.",
