Magnetic separation of amino acids by gold/iron-oxide composite nanoparticles synthesized by gamma-ray irradiation

Amounts of amino acids adsorbed onto the Au/ γ -Fe 2O 3 composite nanoparticles synthesized by gamma-ray irradiation were measured using magnetic separation technique. Cystine and methionine, which are sulfur-containing amino acids, connected to Au by a Au–S bond could be selectively picked up by a...

description Amounts of amino acids adsorbed onto the Au/ γ -Fe 2O 3 composite nanoparticles synthesized by gamma-ray irradiation were measured using magnetic separation technique. Cystine and methionine, which are sulfur-containing amino acids, connected to Au by a Au–S bond could be selectively picked up by a magnet.
