![عکس صفحه اول مقاله: Electrochemiluminescence aptasensor of TiO2/CdS:Mn hybrids for ultrasensitive detection of cytochrome c Electrochemiluminescence aptasensor of TiO2/CdS:Mn hybrids for ultrasensitive detection of cytochrome c](/preview/png/1243296.png)
• An cyt c ECL aptasensor was designed based on TiO2/CdS:Mn hybrids.
• CdS:Mn QDs worked as the ECL emitter and aptamer linker.
• The sensitivity was highly enhanced with using CdS:Mn QDs.
• High specificity was achieved.
• A wide linear range was achieved from 50 fM to 125 pM.
A novel electrochemiluminescence (ECL) aptasensor was proposed for ultrasensitive detection of cytochrome c (cyt c) using CdS:Mn quantum dot-modified TiO2 nanowires (NWs) as electrode. The Mn-doped CdS was deposited on the TiO2 NWs by successive ion layer adsorption and reaction (SILAR) as ECL emitter, on which thiol-modified aptamer of cyt c was attached via Cd–S bond. Due to the high photo-electrical transfer efficiency, the as-prepared aptasensor shows high selectivity and sensitivity towards cyt c with a detection limit of 9.5 fM and a linear range from 50 fM to 125 pM.
