Human schistosomiasis is widespread in tropical and subtropical environments. In this study, a novel open cell with liquid medium perfusion system for electrorotation measurement to detect the viability of schistosomal eggs is proposed. With no solid top or bottom surface, the liquid medium perfusion system solves some of the problems of conventional electrorotation testing systems. This kind of open cell successfully detect schistosome egg viability, most prominently, there can be no adhesion or friction of eggs on the surface to encumber their rotation. This newly proposed system can be used to test more types of biological particles compared to a conventional system used in electrorotation measurement, providing more exact results. The new system can be used for rapid analysis of various biological particles in water, which will be potentially significant to public health.
