چکیده
An ultrasensitive electrochemiluminescence (ECL) detection for Cu2+ was explored using the carboxyl functionalized poly(9,9-dioctylfluorenyl-2,7-diyl) (PS-COOH-co-PFO) dots as the signal label without adding any coreactant.

In this study, for the first time, a simple immunosensor for ultrasensitive recognition of Human Chorionic Gonadotropin (hCG) in serum samples was fabricated by exploiting a simple approach. In this method, a low-cost and sensitive immunosensor was fabricated based on QDs-N-S/Au nanoparticles (NPs) modified Screen-Printed Carbon Electrode (SPCE). It seems that, QDs-N-S/Au NPs/ antibody as a bio...
متن کاملDual role of CdSe quantum dots for simultaneous separation and spectrofluorimetric ultrasensitive determination of heparin
The present study offers a new method based on CdSe quantum dots (QDs) for simultaneous separation and determination of trace levels of heparin (Hep) in human serum samples. In this technique, CdSe QDs perform two different functions in Hep analysis process. Mercaptoacetic acid-capped red CdSe QDs (λex=690 nm) are conjugated to Hep and the Hep-QD conjugation is then used as an extraction...
