Title : Thiolated gold nanoflower for breast cancer associated volatile organic compounds sensing
Abstract:
In this work, gold nanoflowers were synthesized using a simple chemical route in an aqueous medium, assisted by silver nitrate salt, resulting in nanoflowers approximately 400 nm in size. The synthesized nanoflowers were separated from the surfactant using centrifugation and then dispersed in deionized water. These dispersed nanoflowers were subsequently drop-coated onto prepatterned helical electrodes on a glass substrate. To fabricate cross-reactive sensors for the detection of volatile organic compound (VOC) biomarkers of breast cancer, charged thiols were applied to these coated nanoflowers. The surface and structural properties of the deposited nanoflowers were analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD). Finally, the fabricated sensors were tested for their responsiveness to VOCs associated with breast cancer under normal atmospheric conditions, including ambient pressure and temperature. The sensors demonstrated responsiveness to the exposed VOCs, indicating their potential utility in detecting breast cancer biomarkers.
