Determination of anthracene on Ag-Au alloy nanoparticles/overoxidized-polypyrrole composite modified glassy carbon electrodes
(MDPI, 2010)
A novel electrochemical sensor for the detection of anthracene was prepared by
modifying a glassy carbon electrode (GCE) with over-oxidized polypyrrole (PPyox) and
Ag-Au (1:3) bimetallic nanoparticles (Ag-AuNPs). The ...
Electrochemical aptasensor for endocrine disrupting 17β-estradiol based on a poly(3,4-ethylenedioxylthiopene)-gold nanocomposite platform
(MDPI, 2010)
A simple and highly sensitive electrochemical DNA aptasensor with high affinity for endocrine disrupting 17β-estradiol, was developed. Poly(3,4-ethylenedioxylthiophene) (PEDOT) doped with gold nanoparticles (AuNPs) was ...
Phytochemical screening and biological activity studies of five South African indigenous medicinal plants
(Academic Journals, 2010)
Different extracts and fractions of five selected indigenous South African medicinal plants, namely, Cissampelos capensis, Geranium incanum and three Gethyllis species, were subjected to phytochemical screening and testing ...
