PY 2015 BP 1749 EP 1753 VL 49 IS 13 DI 10.1134/S1063782615130035 DE carbon nanotubes; CNT detectors AB The possibility of the fabrication of a fast-response biological sensor based on a composite of single-layer carbon nanotubes and aptamers for the specific detection of proteins is shown. The effect of modification of the surface of the carbon nanotubes on the selectivity and sensitivity of the sensors is investigated. It is shown that carboxylated nanotubes have a better selectivity for detecting thrombin. ER
