제목 Diverse Applications of 3D Nano/Micro Structures Fabricated by Two-Photon-Initiated Polymerization
초록 The emergence of 3D printing technology in the past decade has set off a huge paradigm shift in manufacturing, which is termed as the fourth industrial revolution. In this context, two-photon stereolithography is poised to change the manufacturing at nano/micro scale. Generally, two-photon stereolithography is based on a photopolymerization reaction directly or indirectly initiated by a nonlinear optical molecule capable of simultaneously absorbing two-photons. When a near-infrared ultrashort-pulsed laser is closely focused into a volume of photoactive chemical medium (photoresist), real 3D microstructures can be fabricated using a layer-by-layer accumulating technique. In this lecture, high resolution patterns of polymers, ceramics, noble metals and semiconductors incorporated microstructures fabricated by two-photon-initiated polymerization will be presented. The 3D microstructures containing noble metals or semiconducting quantum dots are of great interest for applications in optoelectronics, photonics and biophotonics due to their ability to change the dielectric properties and refractive index of polymeric structures. In addition, recent developments of novel 3D cancer cell chips for the in vitro 3D cell growth simulation of tumor cells and the activity detection of anticancer drugs is also reported.
