Spongy gel-like layered double hydroxide-alkaline phosphatase nanohybrid as a biosensing material

Formation of new bio-nanohybrid material was obtained by immobilization of alkaline phosphatase within a Mg2Al LDH by soft chemistry'' coprecipitation synthesis, resulting in an original spongy gel-like morphology allowing the preservation of the enzyme structure and activity even at low pH values thanks to the buffering property of the basic host structure.
