Visible indication based on the aggregation of colloidal nanoparticles (NPs) is highly advantageous for rapid on-site detection of biological entities, which even untrained persons can perform without specialized instrumentation. However, since the extent of aggregation should exceed a certain minimum threshold to produce visible change, further(More)
Highly selective mercury detection at partially oxidized graphene/poly(3,4-ethylenedioxythiophene):poly (styrenesulfonate) nanocomposite film-modified electrode Partially oxidized graphene flakes (po-Gr) were obtained from graphite electrode by an elec-trochemical exfoliation method. As-produced po-Gr flakes were dispersed in water with the assistance of
Nanocrystalline zinc oxide (ZnO) particles coated with whey protein (WP) were synthesized in the weak basic aqueous solution condition at room temperature. The X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements confirmed the ZnO/WP nanoscaled composite structure. The average composite granules size was about 300 nm and the(More)
