Paragraph starter

Nanoimprint lithography (NIL) offers a high-throughput, cost-effective method for fabricating nanostructures by employing direct mechanical deformation of resist materials, thereby circumventing the resolution limits imposed by optical diffraction or beam scattering inherent in conventional lithographic approaches. The success of NIL is critically dependent on the selection of appropriate materials for both the imprinting mold and the resist, as well as careful consideration of surface properties to ensure reliable and precise replication of nanoscale features.
