Scalable 3D Nanofabrication via Upconversion

Triplet-Triplet Annihilation Upconversion (TTA-UC) offers a groundbreaking method for volumetric 3D printing at the micro- and nanoscale, applicable to fields like plasmonics, nanophotonics, and biomedicine. Unlike the traditional two-photon absorption process, TTA-UC can be activated by low-power light sources while maintaining the desired quadratic nature for the spatially confined generation of high-energy photons, enabling localized polymerization reactions. Enhanced by advanced resin formulations, sophisticated optical systems, and state-of-the-art deconvolution algorithms, this technology holds significant promise for revolutionizing next-generation micro- and nanoscale fabrication. It uniquely combines high resolution, low power consumption, rapid processing, and scalability, making it a versatile and powerful tool for future developments in various scientific and industrial applications.
