title: Use of a hydrogel polymer for reproducible surface enhanced Raman optical activity (SEROA).
abstract: We present surface enhanced Raman optical activity (SEROA), as well as Raman, SERS and ROA, spectra of D- and L-ribose. By employing a gel forming polyacrylic acid to control colloid aggregation and associated birefringent artefacts we observe the first definitive proof of SEROA through measurement of mirror image bands for the two enantiomers.
