Novel photoelectrochemical immunosensor for MCF-7 cell detection based on n-p organic semiconductor heterojunction
文献摘要：
In this work,we developed a novel photoelectrochemical(PEC)sensor based on n-p organic semicon-ductor heterojunction for sensitive detecting MCF-7 cancer cells.BTA-C4Ph and PM6 were designed as photoactive materials to form n-p heterojunction,which greatly enhanced the photoelectric conversion efficiency.Antibody-modified magnetic nanoparticles were utilized to capture and separate MCF-7 cells from samples.Detection of MCF-7 is ascribed to the loading of MCF-7 onto BTA-C4Ph-PM6 modified elec-trode that resulted in the decrease of photocurrent intensity.The PEC immunosensor displayed a linear concentration ranging from 50 cell/mL to 1×104 cell/mL with a limit of detection(LOD)of 41 cell/mL(S/N=3)for MCF-7.Additionally,the senor also exhibited good stability,excellent selectivity and promi-nent reproducibility.Furthermore,the sensor was successfully applied to detect MCF-7 in whole blood.This work illustrates that n-p heterojunction of organic semiconductor may find wide applications for the preparation of different photoelectrochemical sensors.
