Abstract

Typically, conventional micro-nano fabrication methods are applied to flat surfaces, ensuring precise alignment and resolution at the nanoscale. Nevertheless, when dealing with curved or multi-oriented substrates, the task becomes considerably more intricate, necessitating complex equipment for sample positioning, lithographic alignment, and focusing. This often results in significantly reduced fabrication capabilities compared to standard processes. Recently, our group introduced a straight method to handle micro-structures fabricated by two photon lithography and conformably place them on curved surface target objects by exploiting Van der Walls adhesion of ultra-thin polymeric film used as temporary freestanding support. In this invited lecture, we will review the most recent results of our group with this approach applied to the field of optical meta-surfaces and sensors, highlighting the future directions and the possible extension of the technology to other fields.
