Can we measure heavy metals in water with smartphone?
In the past, heavy metals measurement is performed in the laboratory using bulk machine, for example, inductively-coupled plasma – optical emission spectrometry (ICP-OES). Nowadays, a more user-friendly method is available for home test mostly dipstick. However, dipstick is a qualitative method, then we ask ourselves how we can measure heavy metals quantitatively. Electrochemical technique plays an important role in blood-glucose...
