With positive photoresists, the opposite occurs; two-photon absorption causes the photoresist polymeric chains to break and become soluble to the development solvent, so the reverse structure is ...

but rather from the extreme nonlinearity of photon avalanching and from a unique structure that dampens vibrations in the particles. In future studies, the researchers hope to study new ...

A recent review in Engineering explores multi-photon 3D nanoprinting. This technology, with its unique 3D processing and ...
