Developing non-invasive, sensitive and specific sensing strategies for cancerous cell detection with simple and low cost instrumentations provide great advantages in cancer research and early diagnosis of diseases. In the present work, gold nanoparticles (Au NPs) functionalized with recognition components (folic acid) and signal indicator (ferrocene) was designed to fabricate electrochemical cytosensor...
The possibility of using electrochemical methods to investigate cell immobilization and natural physiological states provides great advances in life science research and public health protection. Herein, cytosensors with surface-confined ferrocene as signal indicator were developed to study the immobilization of human cervical carcinoma (HeLa) cells. With layer-by-layer (LBL) technique positively...
