New concept of micro/nano tools working in water solutuon has been proposed by the author. A real three dimensional micro fabrication process using photo curable polymer named "micro/nano stereolithography "has been also developed by the author's group. The latest version of this process achieved 100 nm in 3D resolution and freely movable micro/nano mechanism are easily fabricated within 20 min. Nano tweezers and nano needle with two degrees of freedom were successfully fabricated without any assembly process. Cell and delicate biological materials can be remotely handled with neither any micro actuators nor lead wire. It was verified that this light-driven micro tool has precise force control with 10 FtN. These light-driven micro tools contribute to cellular biology as well as medical tools. The second application of microstereolithography is the biochemical IC chips for both micro chemical analysis and synthesis. Unlike conventional "lab. on a chip" and "micro total analysis system (micro-TAS), our biochemical IC has micro pumps and active valves in one chip. Users can construct their own micro chemical device by themselves. The advanced biochemical IC chip-set for "on chip cell-free protein synthesis" has been prototyped and verified experimentally. A luminous enzyme of fire fly so called " Luciferase" and useful bio-marker protein "GFP" were synthesized successfully. According to above results, the biomchemical IC chips will be useful to "Order-made medicine" in near future.
