Sensor response to interferents, and sensor mechanism. a Emission intensity response of the nanosensor to various proteins. b Emission wavelength response of the nanosensor to protein interferents. c SDS-PAGE gel where: lane 2 contains albumin at pH 7 incubated at room temperature for 30 min; lane 3 contains albumin incubated at pH 2 in PBS at room temperature for 30 min followed by neutralization; lane 4 contains albumin incubated in urine at pH 2 for 30 min followed by neutralization. d Emission intensity response of the nanosensor to intact albumin (bars 1–2, corresponding to lanes 2–3, respectively, in panel c) and degraded albumin (bar 3, corresponding to lane 4 in panel c). e Emission wavelength response of the nanosensor to intact albumin (bars 1–2, corresponding to lanes 2–3 in panel c) and degraded albumin (bar 3, corresponding to lane 4 in panel C). f A proposed model of albumin interaction with the carboxy-PCD-SWCNT nanosensor. Data in panels a, b and d, e present the (9, 4) nanotube chirality. Error bars represent standard deviation for n = 3 technical replicates
