（1）Anti-biofouling: Utilization of a variety of structures, which repel life forms purely due to surface minimization, unfavorable settlement sites as well as light-life form interaction due to photocatalytic properties of the surface. This will be achieved by means of Oswald ripened metal-oxide surfaces on structured templates and subsequent analyzation of the interaction of the structures and life forms with a recently home-build 3D microscope. This research is intended with the collaboration of HIT Weihai campus. （2）Drug delivery in collaboration with Prof. Qiang He: I intend to Utilize the same 3D microscope, and optical tweezers, which I currently build to detect and analyze the 3D movement and control of drug delivery systems.
