  Motivated by recent observations of chiral-induced magnetization and
spin-selective transport we studied the effect of chiral molecules on
conventional BCS superconductors. By applying scanning tunneling spectroscopy,
we demonstrate that the singlet-pairing s-wave order parameter of Nb is
significantly altered upon adsorption of chiral polyalanine alpha-helix
molecules on its surface. The tunneling spectra exhibit zero-bias conductance
peaks embedded inside gaps or gap-like features, suggesting the emergence of
unconventional triplet-pairing components with either d-wave or p-wave
symmetry, as corroborated by simulations. These results may open a way for
realizing simple superconducting spintroinics devices.
