  Gold nanoflowers are known for their use as efficient host for surface
enhanced Raman scattering of organic dye molecules. In this article, gold
nanoflowers have been synthesised and rhodamine 6 G (R6G) molecules have been
used as probe molecules. It is found that the gold nanoflowers can detect the
presence of R6G molecules upto 10^{-10} M. The petals of these nanoflowers play
an important role for the enhancement of Raman signals, and the intensity of
Raman signals is enhanced many folds in presence of gold nanoflowers - the
enhancement factor is of the order of 10^6. This is explained in terms of
electromagnetic mechanism.
