Outline of Final Research Achievements

A droplet shrinkage and gelation method was used to develop a method of a quantitative analysis of low toxic aqueous samples from natural resources. In this project, two relevant methods were developed; (1) a method to stably form droplets enclosing aqueous sample and (2) a method to condense solute in sample droplets.
