We develop new technologies for micro/nano-scale machining and surface processing in order to improve the added value of industrial products. Besides mechanical methods, we also use electrical/chemical methods, lasers and ultrasonic vibrations to precisely modify the shapes and surface properties of new materials, such as super hard alloys, optical crystals, semiconductors, glass, diamond, CFRP, and ceramics.

We fabricate thin films with multi-function by controlling surface morphology with nanoscale order. Superhydrophobic coating for house surface, highly durable transparent anti-fouling coatings for windows, anti-“blood adhesion” for medical equipments, anti-reflection films for microscopy, and hemostatic micro capsules are studied in our laboratory.

Novel methods for large-scale and fine synthesis of nanoclusters, super-small particles of sub-bulk size which have unusual and various functionalities, have been developed. Among them we display:

Diamond-like carbon (DLC) films have attractive properties such as high gas barrier and low friction coefficient, and been used in many areas. In fact, there are some industrial applications to packaging and automobile parts etc. Here, we show DLC-coated medical device which contains fluorine (F-DLC) with antithrombogenicity property.
