Peanut skin extract mediated synthesis of gold nanoparticles, silver nanoparticles and gold-silver bionanocomposites for electrochemical Sudan IV sensing.

Sustainable methods are needed for rapid and efficient detection of environmental and food pollutants. The Sudan group of dyes has been used extensively as adulterants in food and also are found to be polluting the soil and water bodies. There have been several methods for detection of Sudan dyes, but most of them are not practical enough for common use. In this study, the electrochemical detectio...
