Outline of Final Research Achievements

We have fabricated the nanoparticles of Rh and Pd by gas evaporation method. The particle sizes of both Rh and Pd are estimated to be approximately 1-4 nm. Although a sulfur-containing molecules (mainly thiol-based molecules) adsorbed on the Rh nanoparticle surface chemically adsorbs but the adsorbed molecules does not show a dissociation reaction. Moreover the Rh nanoparticles does not show the hydrogen absorbing/releasing reaction. On the other hand, for the Pd nanoparticles, it is found that the hydrogen absorbing/releasing reaction rate is remarkably slow in comparison with the rate for without sulfur poisoning. Based on this result, we are planning to continue applying to cancer screening in the future.
