Highly Sensitive and ultra-small Rhenium (Re) metal nanoparticles (NPs) were successfully stabilized in water by the staging and fencing action of the versatile biomolecule DNA that resulted in two distinct aggregated chain-like morphologies with average grain sizes of 1.1±0.1nm and 0.7±0.1nm for the very first time within a minute of reaction time. Re NPs are formed by the borohydride reduction of...
A UV-photoirradiation technique has been demonstrated for an innovative, simple, one-step process for the synthesis of semi-conducting Au–Ag aggregated branched nanoalloys on DNA within 3h. The nanostructures having the diameters range from 4 to 12nm with length in the micrometer range. During Au–Ag alloy nanostructures synthesis, the DNA acts as both a reducing agent and a non-specific capping agent...
