Description |
Osmium (Os) organosol on DNA scaffold has been synthesized by utilizing a homogeneous reduction route. The
synthesis was done by the reduction of OsO4 with tetrabutylammonium borohydride (TBABH4) in the presence of DNA in
acetone within 10 min of stirring at room temperature. Different morphologies were synthesized by varying the DNA to OsO4
molar ratio and controlling the other reaction parameters. The eventual diameters of the individual Os particles in organosol
were ∼1−3 nm, and the nominal lengths of the wires were ∼1−2 μm. The potentiality of the Os organosol was tested in two
different applications: one is the catalytic hydrogenation of cyclohexene to cyclohexane and other is the surface enhanced Raman
scattering (SERS) studies. The SERS study has been examined using MB as a Raman probe, and the EF value is found to be the
highest in the case of Os organosol having aggregated wires (short size) compared to longer wires. The fast synthesis of Os
organosol on DNA and their potential catalytic and SERS activity will be found to be very useful in the near future for the
catalytic applications of various organic reactions and in the fields of sensors, electronic devices, and fuel cells.
