Abstract
Provided is a method of manufacturing a diamond knife for an ultra-microtome, including determining a shape and size of a knife, performing a multiphase flow analysis on movement of a droplet at a fore-end of the knife with the determined shape and size, processing a fine pattern to ensure hydrophobic property according to a result of the flow analysis, and grinding a blade of the knife after the processing of the fine pattern to minimize an interval between the pattern and the blade and, thus, a knife blade is always maintained in a wet state due to a droplet movement between a hydrophobic fine pattern and a hydrophilic surface to continuously generate ultrathin slices.
