中文摘要	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 charged ferrocene functionalized poly(allylamine hydrochloride) (fc-pah) and negatively charged single-wall carbon nanotubes (swnts) were alternately assembled on 3-mercaptopropionic acid (mpa) modified gold substrates. the as-prepared cytosensors presented good biocompatibility and hela cells could keep viability for 72 h on the materials according to the proliferation results. with differential pulse voltammetry (dpv) measurements the cytosensors exhibited high sensitivity to the detection of hela cells within a wide concentration range from 10 to 10(7) cells/ml.
