The study presents a new approach for rapid and ultrasensitive detection of maltol using a glassy carbon electrode (GCE) modified with graphene oxide-wrapped tin oxide@carbon nanospheres (SnO2@C@GO). The morphological and components properties of SnO2@C@GO nanocomposites were investigated by means of X-ray diffraction spectroscopy, Raman spectroscopy, field emission scanning electron microscopy, high...
Polyaniline/graphene nanocomposite (PANI/G) was synthesized by an in situ polymerization procedure. The microstructure of PANI/G was characterized to be a mixture of PANI nanowires and graphene sheets by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Energy Dispersive X-Ray Fluoresence Spectrometer (EDX). PANI/G was used to modify glassy carbon electrodes to detect...
Molecular cancer biomarkers will be instrumental in the screening and detection of cancer. Development of a hand held, non destructive microsensor for distinguishing breast cancer cells in real time is essential for breast cancer therapeutic options. Vascular Endothelial Growth Factor (VEGF) is a potent cytokine, which is normally over-expressed in malignant breast tumor cells. In our work, we are...
