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 λ ‐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.
