A 3,4-dihydroxyphenethylcarbamodithioate capped biogenic Fe₃O₄ magnetic nanocomposite has been synthesized using a watermelon rind extract for the removal of Hg(ii) ions with a facile recyclability.

Water-dispersible diethyl-4-(4-amino-5-mercapto-4H-1,2,4-triazol-3-yl)phenyl phosphonate (DEAMTPP)-capped biogenic Fe₃O₄ magnetic nanocomposite has been synthesized using Ananas comosus peel pulp extract for rapid removal of Cd(ii) ions from water.

A new Cu nanoparticles embedded porous carbon composite was prepared by simple pyrolysis of HKUST-1, which shows high efficient (detection limit: 3.2 × 10 ⁻⁹ M) glucose sensing ability with high selectivity.
