Description:
Phytochelatins (PCs), oligomers of glutathione, naturally chelate heavy metals (HMs) in aqueous solution; small peptides such as these cannot be used as covalently bound bioprobes on transducer surfaces due to their propensity to induce corrosion of standard sensor supports such as gold and porous silicon (PSi). In this work, we chemically modify a commercial PC oligopeptide with a six poly-lysine (Lys) chain, thereby changing its isoelectric point from 4.2 to 6.9. PC-Lys bioprobes were successfully immobilized on both ...
