Studies on the Aptasensor Miniaturization for Electrochemical Detection of Lead Ions.

Lead poses severe effects on living organisms, and since Pb ions tend to accumulate in different organs, it is crucial to monitor Pb concentration in samples such as water and soil. One of the approaches is the utilization of biosensors combined with aptamer-based layers for the electrochemical detection of lead ions. Herein, we present the studies of applying miniaturized screen-printed transducers as solid surfaces to fabricate aptamer layers.
