以猪血清白蛋白（PSA）和小鼠免疫球蛋白（MlgG）为传感介质，研究了碳纳米管场效应晶体管（NTFET）的生物传感选择性。从使用朗缪尔方程的分析，我们证实了PSA和MlgG传感器表现出良好的选择性。观察到，使用PSA和MlgG传感器的选择性感测对于分别高达500和5000 nM的PSA和MlgG浓度是可能的。
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.
