摘要

Herein, Rh organosol stabilized DNA was prepared utilizing a simple wet-chemical route within just 2 min. Rh organosol was obtained by reducing the aq.RhCl3 solution with solid Tetrabutylammonium borohydride (TBABH4) at room temperature. By varying the concentrations of both aq. DNA solution and aq. Rh (III) chloride solution, chain-like morphologies of Rh organosol with small and large particles of Rh were prepared. Previous work on Rh organosol had not resulted in a stable colloidal solution, whereas the use of DNA in this work ensured Rh organosol as a stable colloidal solution with the preferred chain-like morphological Rh NPs. The average diameter of the synthesized small size Rh organosol and large size Rh organosol were found to be ~ 3.5 ± 0.5 nm and ~ 10 ± 2 nm, respectively. Rh organosol with varying particle sizes were utilized in surface enhanced Raman scattering (SERS) studies and found to be effective substrates for Methylene blue (MB) dye detection. The calculated enhancement factor (EF) values for DNA stabilized small size and large size Rh organosol were found to be ~ 4.1 × 105 and ~ 6.6 × 104, respectively. Both small size and large size Rh NPs @DNA were also examined as catalysts towards the reduction of a few nitroarene compounds. The catalytic reduction activity was retained even when recycled up to 10 times. Rh NPs @DNA were tremendously stable over more than four months when kept in via sealed glass container at ~ 5–8 °C. This Rh organosol can easily be re-dispersed in any of the organic or aqueous solvents.
