In recent years, the continuous and accumulative
discharge of toxic and contaminating compounds to
the environment makes necessary to propose precise
and quick methods for their detection and quantitation.
Especially when one considers that the environmental
impact of some of these emerging contaminants has
not been clearly determined. Enzyme-based biosensors
are an interesting alternative when inspecting different
pollutants present in the environment in a quick, efficient,
automatized, and economic way. Oxidative enzymes such
as peroxidases and polyphenol oxidases (laccases and
tyrosinases) are versatile and highly functional enzymes
used for analyte recognition. Therefore, these enzymes
are considered attractive and interesting biomolecules to
act as recognition elements in biosensors. In this regard,
detection of pollutants such as pesticides, phenols,
heavy metals, and pharmaceutical compounds by using
oxidative enzymes as recognition elements in biosensors
is a versatile field, and it is the focus of the present review.
