摘要：

The biosensing selectivity of a carbon nanotube field-effect transistor (NTFET) was examined using a mixture of pig serum albumin (PSA) and mouse immune globulin (MlgG). From analyses using the Langmuir equation, we confirmed that the PSA and MlgG sensors demonstrated good selectivity. It was observed that selective sensing using PSA and MlgG sensors is possible for PSA and MlgG concentrations of up to 500 and 5000 nM, respectively.
