Life revolves around water, so a strict control on its quality is vital to
guarantee human health and protection of biodiversity. However,
nowadays, industrialization accelerated by human population growth
and people's lack of information about possible environmental
problems end up polluting water bodies with biological and artificial
pollutants. Including, the presence of heavy metals in drinking water
can have serious repercussions on health such as intestinal and
kidneys diseases, accompanied even by severe brain damage.
Therefore, this work aims to develop a biosensor that is at the
service of detecting two harmful heavy metals, mercury, and lead.
Among biosensors, the amperometric enzymatic biosensor was
selected due to the advantages they offer over others, for instance,
simplicity, short time responses and miniaturization potential are
some of these features. At same time, an innovative design will
allow to detect heavy metals in an easy and cost-effective way
without neglecting the ease of transport and handling with a series
of simple instructions that allow access not only to scientists but
also to standard or unskilled users. The acting principle includes the
analysis of urease enzyme behavior in the presence of specific heavy
metals since it is inhibited at -0.03 V to 0.0 V reaching the
formulation of calibration curves that show the concentration of an
analyte by considering the variation in the current flow. The sensor
has maximum dimensions of 76.2 mm long, 39.54 mm high and 62
mm wide with an approximate weight of 218 grams. The initial cost
per measured sample is estimated to be approximately 12 USD.
