Abstract
The drug sensing properties of procaine and berberine drug sensors based on ruthenium dioxide thin film were investigated. Ruthenium dioxide (RuO₂) membrane prepared using a sputtering method was used as substrates for the drug sensors. The procaine and berberine drug sensors were prepared using a drug-sensitive membrane that measured the procaine and berberine concentration in a linear range from 1×10(-2) M to 1×10(-6) M and from 1×10(-2) M to 1×10(-7) M, respectively. The drift rates and hyteresis widths of these ruthenium dioxide based drug sensors were also investigated.
