Selective Protein Sensing Using a Carbon Nanotube Field-Effect Transistor
Abstract: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 (MIgG). From analyses using the Langmuir equation, we confirmed that the PSA and MIgG sensors demonstrated good selectivity. It was observed that selective sensing using PSA and MIgG sensors is possible for PSA and MIgG concentrations of up to 500 and 5000 nM, respectively.
