A label-free electrochemical immunosensor for sensitive detection of α-fetoprotein (AFP) was developed based on graphene/SnO2/Au nanocomposite. The graphene/SnO2/Au nanocomposite modified glassy carbon electrode was used to immobilize α-fetoprotein antibody (anti-AFP) and to construct the immunosensor. Results demonstrated that the peak currents of(More)
Herein, a dual signal amplification strategy was employed in fabricating ultrasensitive electrochemical immunosensor for alpha fetoprotein (AFP) detection, which was realized by utilizing of ZnO nanorods/Au nanopaticles hybridized reduced graphene nanosheet (Au/ZnO/RGO) and horseradish-peroxidase (HRP) bioconjugated detection antibody (Ab2) functionalized(More)
BACKGROUND To study the association between psychosocial factors and the development of lung cancer. METHODS Case-control matched study was employed in the study. A standardized life event, social support and defense mechanisms interview was administered respectively. Total 118 lung cancer patients who were diagnosed pathologically were chosen as case(More)
The objective of the present study was to evaluate the phytotoxicity and oxidant stress of the gold nanorods toward watermelon, and hence give a quantitative risk assessment of both seeds and plants phase. The seed germination, the activity of antioxidant enzymes, and the contents of soluble protein and malondialdehyde (MDA) have been measured while the(More)
Nanoparticles (NPs) have been exploited in a diverse range of products in the past decade or so. However, the biosafety/environmental impact or legislation pertaining to this newly created, highly functional composites containing NPs (otherwise called nanomaterials) is generally lagging behind their technological innovation. To advance the agenda in this(More)
