Homogenous spherical mosslike assembly of Pd nanoparticles by using DNA compaction: Application of Pd-DNA hybrid materials to volume-expansion hydrogen switches
The formation of Pd-DNA nanohybrid structures, and the use of these materials as chemiresistive hydrogen sensors is described. Interaction of Pd(II) complexes with A-DNA leads to formation of a small compacted globular state, and reduction of the Pd(II) complexes results in homogenous spherical mosslike assembly of Pd nanoclusters. The mosslike Pd materials show a unique switch response to hydrogen adsorption.
