Cell chip with a thiolated chitosan self-assembled monolayer to detect the effects of anticancer drugs on breast normal and cancer cells

- Thiolated chitosan was fabricated to establish cytophilic environment by self-assembly.
- Thiolated chitosan was best for enhancing electrochemical signals of cells.
- Redox properties of normal and cancer cells were detected by cyclic voltammetry.
- Effects of anticancer drugs on cells were monitored by thiolated chitosan cell chip.
- Thiolated chitosan cell chip can be usefully applied for anticancer drug screening.
