A new way to look at cancer cell detection

Cancer cell detection based on the interaction between an anticancer drug and cell membrane components

A novel cancer cell detection method, based on the interaction between daunomycin (DAN – an anticancer drug used in chemotherapy) and cell membrane components, has been developed by scientists in South Korea.

The method uses the electrochemical and fluorescence behaviour of DAN and uses an aptamer probe immobilised on a conducting polymer-gold nanoparticle composite film.

he aptamer sensor probes using electrochemical impedance spectroscopy and fluorescence microscopy. The method differentiates between cancerous and non-cancerous cells at low concentrations (0.01μM).
