Abstract

Two-Photon stereolithography is considered to be a promising technique for 3D microfabrication. In particular, microstructures containing noble metals or semiconducting quantum dot nanocrystals are of interest for applications in optoelectronics, photonics and biophotonics. Quantum size effects become relevant in noble metal nanoparticles. Because of this there are many issues regarding the use of photo-lithography in fabricating noble metal containing microstructures including undesirable optical and thermal effects. Realizing well defined ordered structures containing noble metals and quantum dots are hence a challenge in the realm of microfabrication. In this lecture, 3D organic-inorganic hybrid structures achieving by the different approaches will be presented. In addition, recent developments of novel 3D cancer cell chips using a three-floor hierarchical 3D pyramid structure for the in vitro 3D cell growth simulation of tumor cells and detection of anticancer drugs is also reported.
