A photoelectrochemical aptasensor based on p-n heterojunction CdS-$ Cu_{2} $O nanorod arrays with enhanced photocurrent for the detection of prostate-specific antigen
Abstract A sensitive photoelectrochemical (PEC) aptasensor was constructed for prostate-specific antigen (PSA) detection using an enhanced photocurrent response strategy. The p-n heterostructure CdS-$ Cu_{2} $O nanorod arrays were prepared on Ti mesh (CdS-$ Cu_{2} $O NAs/TM) by a simple hydrothermal...

| 520 | |a Abstract A sensitive photoelectrochemical (PEC) aptasensor was constructed for prostate-specific antigen (PSA) detection using an enhanced photocurrent response strategy. The p-n heterostructure CdS-$ Cu_{2} $O nanorod arrays were prepared on Ti mesh (CdS-$ Cu_{2} $O NAs/TM) by a simple hydrothermal method and successive ionic-layer adsorption reactions. Compared with the original CdS/TM, the synergistic effect of p-n type CdS-$ Cu_{2} $O NAs/TM and the internal electric field realizes the effective separation of photoinduced electron–hole pairs and improves the PEC performance. In order to construct the aptasensor, an amino-modified aptamer was immobilized on CdS-$ Cu_{2} $O NAs/TM to serve as a recognition unit for PSA. After the introduction of PSA, PSA was specifically captured by the aptamer on the PEC aptasensor, which can be oxidized by photogenerated holes to prevent electron–hole recombination and increase photocurrent. Under optimal conditions, the constructed PEC aptasensor has a linear range of 0.1–100 ng·$ mL^{−1} $ and a detection limit as low as 0.026 ng·$ mL^{−1} $. The results of aptasensor detection of human serum indicate that it has broad application prospects in biosensors and photoelectrochemical analysis. | ||

The p-n heterostructure CdS-$ Cu_{2} $O nanorod arrays were prepared on Ti mesh (CdS-$ Cu_{2} $O NAs/TM) by a simple hydrothermal method and successive ionic-layer adsorption reactions. Compared with the original CdS/TM, the synergistic effect of p-n type CdS-$ Cu_{2} $O NAs/TM and the internal electric field realizes the effective separation of photoinduced electron–hole pairs and improves the PEC performance. In order to construct the aptasensor, an amino-modified aptamer was immobilized on CdS-$ Cu_{2} $O NAs/TM to serve as a recognition unit for PSA. After the introduction of PSA, PSA was specifically captured by the aptamer on the PEC aptasensor, which can be oxidized by photogenerated holes to prevent electron–hole recombination and increase photocurrent. Under optimal conditions, the constructed PEC aptasensor has a linear range of 0.1–100 ng·$ mL^{−1} $ and a detection limit as low as 0.026 ng·$ mL^{−1} $. The results of aptasensor detection of human serum indicate that it has broad application prospects in biosensors and photoelectrochemical analysis.

The p-n heterostructure CdS-$ Cu_{2} $O nanorod arrays were prepared on Ti mesh (CdS-$ Cu_{2} $O NAs/TM) by a simple hydrothermal method and successive ionic-layer adsorption reactions. Compared with the original CdS/TM, the synergistic effect of p-n type CdS-$ Cu_{2} $O NAs/TM and the internal electric field realizes the effective separation of photoinduced electron–hole pairs and improves the PEC performance. In order to construct the aptasensor, an amino-modified aptamer was immobilized on CdS-$ Cu_{2} $O NAs/TM to serve as a recognition unit for PSA. After the introduction of PSA, PSA was specifically captured by the aptamer on the PEC aptasensor, which can be oxidized by photogenerated holes to prevent electron–hole recombination and increase photocurrent. Under optimal conditions, the constructed PEC aptasensor has a linear range of 0.1–100 ng·$ mL^{−1} $ and a detection limit as low as 0.026 ng·$ mL^{−1} $. The results of aptasensor detection of human serum indicate that it has broad application prospects in biosensors and photoelectrochemical analysis.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Prostate-specific antigen</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CdS-Cu</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">O nanorod arrays</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Photoelectrochemical aptasensor</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Signal amplification</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Qu, Fengli</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lu, Limin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Analytical and bioanalytical chemistry</subfield><subfield code="d">Berlin : Springer, 2002</subfield><subfield code="g">412(2020), 4 vom: 02.

A photoelectrochemical aptasensor based on p-n heterojunction CdS-$ Cu_{2} $O nanorod arrays with enhanced photocurrent for the detection of prostate-specific antigen |
| abstract |
Abstract A sensitive photoelectrochemical (PEC) aptasensor was constructed for prostate-specific antigen (PSA) detection using an enhanced photocurrent response strategy. The p-n heterostructure CdS-$ Cu_{2} $O nanorod arrays were prepared on Ti mesh (CdS-$ Cu_{2} $O NAs/TM) by a simple hydrothermal method and successive ionic-layer adsorption reactions. Compared with the original CdS/TM, the synergistic effect of p-n type CdS-$ Cu_{2} $O NAs/TM and the internal electric field realizes the effective separation of photoinduced electron–hole pairs and improves the PEC performance. In order to construct the aptasensor, an amino-modified aptamer was immobilized on CdS-$ Cu_{2} $O NAs/TM to serve as a recognition unit for PSA. After the introduction of PSA, PSA was specifically captured by the aptamer on the PEC aptasensor, which can be oxidized by photogenerated holes to prevent electron–hole recombination and increase photocurrent. Under optimal conditions, the constructed PEC aptasensor has a linear range of 0.1–100 ng·$ mL^{−1} $ and a detection limit as low as 0.026 ng·$ mL^{−1} $. The results of aptasensor detection of human serum indicate that it has broad application prospects in biosensors and photoelectrochemical analysis. © Springer-Verlag GmbH Germany, part of Springer Nature 2020 |
