Problems solved by technology

However, the existing process of regulating the ion concentration in the liquid is often still performed manually off-chip. On-chip dilution or mixing will change the original concentration of other solutes while adjusting the ion concentration, which greatly limits portable devices. and integrated development of lab-on-a-chip and its promotion in practical fields
