As an efficient modified electrode material for the detection of heavy metal ions, bismuth nanoparticles (BiNPs) were loaded on cobalt ferrite (CoFe2O4), a unique magnetic photocatalytic material, to fabricate a highly sensitive sensor.
A highly sensitive sensor based on ZnO@SiO2 nanospheres has been developed for the detection of ascorbic acid. The developed sensor is very simple and has been fabricated using low cost materials.
