Effect of the Chain Length of a Modified Layer and Surface Roughness of an Electrode on Impedimetric Immunosensors

Abstract An ultrasensitive label-free impedimetric immunosensor is constructed by modifying a 3-mercaptoproponic acid (MPA) monolayer on highly rough gold nanostructure (AuNS)-electrodeposited screen printed carbon electrodes (SPCEs) for the detection of small molecular weight drugs (SMWDs), such as...

520			\|a Abstract An ultrasensitive label-free impedimetric immunosensor is constructed by modifying a 3-mercaptoproponic acid (MPA) monolayer on highly rough gold nanostructure (AuNS)-electrodeposited screen printed carbon electrodes (SPCEs) for the detection of small molecular weight drugs (SMWDs), such as salbutamol (SAL). The SPCEs preoxidized in a 0.1 M $ H_{2} %$ SO_{4} $ solution (called po-$ SPCE_{H2SO4} $) are electrodeposited with the AuNS to increase the roughness factor to 23.64 ± 1.76, larger than the AuNS/po-$ SPCE_{NaOH} $ or the AuNS/po-SPCE{ in =PBS}. Furthermore, the MPA modified layer as a link for the anti-SAL immobilization to give the immunosensors an impedimetric signal-to-noise ratio larger than the 11-mercaptoundecanoic acid- and 16-mercaptohexadecanoic acid-modified layer, due to the lower interfacial impedance of the MPA monolayer. The MPA/AuNS/po-SPCEH2SO4-based immunosensors have a wide linear range of 1 fg $ mL^{−1} $ to 1 ng $ mL^{−1} $ and a limit of detection of 0.6 fg $ mL^{−1} $. Moreover, the immunosensors can practically quantify the SAL concentrations in 1000 times-diluted serum samples with good recovery.

The SPCEs preoxidized in a 0.1 M $ H_{2} %$ SO_{4} $ solution (called po-$ SPCE_{H2SO4} $) are electrodeposited with the AuNS to increase the roughness factor to 23.64 ± 1.76, larger than the AuNS/po-$ SPCE_{NaOH} $ or the AuNS/po-SPCE{ in =PBS}. Furthermore, the MPA modified layer as a link for the anti-SAL immobilization to give the immunosensors an impedimetric signal-to-noise ratio larger than the 11-mercaptoundecanoic acid- and 16-mercaptohexadecanoic acid-modified layer, due to the lower interfacial impedance of the MPA monolayer. The MPA/AuNS/po-SPCEH2SO4-based immunosensors have a wide linear range of 1 fg $ mL^{−1} $ to 1 ng $ mL^{−1} $ and a limit of detection of 0.6 fg $ mL^{−1} $. Moreover, the immunosensors can practically quantify the SAL concentrations in 1000 times-diluted serum samples with good recovery.

The SPCEs preoxidized in a 0.1 M $ H_{2} %$ SO_{4} $ solution (called po-$ SPCE_{H2SO4} $) are electrodeposited with the AuNS to increase the roughness factor to 23.64 ± 1.76, larger than the AuNS/po-$ SPCE_{NaOH} $ or the AuNS/po-SPCE{ in =PBS}. Furthermore, the MPA modified layer as a link for the anti-SAL immobilization to give the immunosensors an impedimetric signal-to-noise ratio larger than the 11-mercaptoundecanoic acid- and 16-mercaptohexadecanoic acid-modified layer, due to the lower interfacial impedance of the MPA monolayer. The MPA/AuNS/po-SPCEH2SO4-based immunosensors have a wide linear range of 1 fg $ mL^{−1} $ to 1 ng $ mL^{−1} $ and a limit of detection of 0.6 fg $ mL^{−1} $. Moreover, the immunosensors can practically quantify the SAL concentrations in 1000 times-diluted serum samples with good recovery.</subfield></datafield><datafield tag="650" ind1=" "

title_auth	Effect of the Chain Length of a Modified Layer and Surface Roughness of an Electrode on Impedimetric Immunosensors
abstract	Abstract An ultrasensitive label-free impedimetric immunosensor is constructed by modifying a 3-mercaptoproponic acid (MPA) monolayer on highly rough gold nanostructure (AuNS)-electrodeposited screen printed carbon electrodes (SPCEs) for the detection of small molecular weight drugs (SMWDs), such as salbutamol (SAL). The SPCEs preoxidized in a 0.1 M $ H_{2} %$ SO_{4} $ solution (called po-$ SPCE_{H2SO4} $) are electrodeposited with the AuNS to increase the roughness factor to 23.64 ± 1.76, larger than the AuNS/po-$ SPCE_{NaOH} $ or the AuNS/po-SPCE{ in =PBS}. Furthermore, the MPA modified layer as a link for the anti-SAL immobilization to give the immunosensors an impedimetric signal-to-noise ratio larger than the 11-mercaptoundecanoic acid- and 16-mercaptohexadecanoic acid-modified layer, due to the lower interfacial impedance of the MPA monolayer. The MPA/AuNS/po-SPCEH2SO4-based immunosensors have a wide linear range of 1 fg $ mL^{−1} $ to 1 ng $ mL^{−1} $ and a limit of detection of 0.6 fg $ mL^{−1} $. Moreover, the immunosensors can practically quantify the SAL concentrations in 1000 times-diluted serum samples with good recovery. © The Japan Society for Analytical Chemistry 2017
