An electrochemical sensor for paracetamol based on an ...

+

An electrochemical sensor combining a molecularly imprinted technique and an electropolymerization method is developed in this work. A molecularly imprinted polymer film was fabricated by electropolymerizing ophenylenediamine in the presence of paracetamol after depositing carboxyl functionalized multiwalled carbon nanotubes onto a glassy carbon electrode surface.

Electrochemical gas sensor

+

Sensors are usually designed so that the gas supply is limited by diffusion and thus the output from the sensor is linearly proportional to the gas concentration. This linear output is one of the advantages of electrochemical sensors over other sensor technologies, ( infrared), whose output must be linearized before they can be used. A linear output allows for more precise measurement of ...
