A disposable indium-tin-oxide sensor modified by gold nanorod–chitosan nanocomposites for the detection of H2O2 in cancer cells†
Abstract
Integrating a disposable ITO electrode modified by gold nanorod–chitosan nanocomposites, a paper-based electroanalytical device for the real-time detection of H2O2 released from cancer cells has been developed. It provided a portable platform for biological and biomedical studies dealing with living cells.
