Nanoscale Palladium Metallization of DNA

Abstract

A magnetite colloid was prepared in alkaline solution according to the procedure published by Massart [11]. An aqueous solution containing 2.3 g (8.5 mmol) FeCl 3 ×6H 2 O in 4 mL H 2 O and 1.69 g (4.3 mmol) Fe(NH 4) 2 (SO 4) 2 in 1 mL of 2 M HCl, was added to 50 mL of 1 M (CH 3) 4 NOH×5H 2 O. The resulting black suspension was stirred for 1 h at room… (More)
