Explores curcumin's interaction with DNA using novel modified electrodes, suggesting a rapid screening tool for small molecules.

To investigate the interaction between curcumin and DNA using modified electrodes for electrochemical analysis.
Constructed pencil graphite electrodes modified with chitosan, gold, and ionic liquid.
Evaluated electrochemical behavior using cyclic voltammetry and electrochemical impedance spectroscopy.
Optimized DNA concentration and immobilization time on the electrode surface through cyclic voltammetry.
Determined curcumin concentration using differential pulse voltammetry.
Analyzed curcumin-DNA interaction at various time intervals using EIS.
Detection limit for curcumin was established at 0.29 µg/mL (0.78 µM).
The electrochemical method showed efficiency and user-friendliness.
Provided a rapid screening tool for small molecule interactions with DNA.
