A highly sensitive and selective immunoassay for the detection of tetrabromobisphenol A in soil and sediment.
Tetrabromobisphenol A is the most widely used brominated flame retardant. A sensitive and selective enzyme-linked immunosorbent assay (ELISA) for the detection of tetrabromobisphenol A was developed.… Expand
Development of an enzyme-linked immunosorbent assay specific to Sudan red I.
To obtain antibodies to develop an enzyme-linked immunosorbent assay (ELISA) for the analysis of Sudan red I, haptens were designed and synthesized via four different strategies: (i) attachment of a… Expand
A sensitive and selective enzyme-linked immunosorbent assay for the analysis of Para red in foods.
Para red is a synthetic dye and a potential genotoxic carcinogen. A hapten mimicking Para red structure was synthesized by introducing a carboxyl to the naphthol part of Para red and coupled to… Expand
Efficacy of systemic insecticides on the gall wasp Quadrastichus erythrinae in wiliwili trees (Erythrina spp.).
BACKGROUND Erythrina gall wasp (EGW), Quadrastichus erythrinae Kim, was first found on Oahu Island, Hawaii, in April 2005. Its rapid spread and infestation in wiliwili trees (Erythrina spp.) have… Expand
Magnetic and Mössbauer Spectroscopy Studies of NiFe2O4/SiO2 Nanocomposites Synthesized by Sol-Gel Method
Single-phase NiFe2O4 nanoparticles dispersed in SiO2 (30 wt %) matrix were synthesized by sol-gel method. The effects of the annealing temperature on the structural and magnetic properties of the… Expand
Strip-based immunoassay for the simultaneous detection of the neonicotinoid insecticides imidacloprid and thiamethoxam in agricultural products.
A semiquantitative strip immunoassay was developed for the rapid detection of imidacloprid and thiamethoxam in agricultural products using specific nanocolloidal gold-labeled monoclonal antibodies.… Expand
