Synergistically　taking　the　advantage　of　distinctive　porous　matrix,　luminophore　and　functional　nanoparticles,　we　prepared　functional　nanocomposite　hydrogel　combining　the　hydrophilic　three-dimensional　network　of　hydrogels　as　matrix　for　the　adsorption　of　luminophore,　Ru(bpy)(3)(2+),　and　in　situ　grown　gold　nanoparticles　(AuNPs)　as　the　conductive.　Interestingly,　the　designed　nanocomposite　hydrogel　shows　external　pressure　resposnsive　properties,　which　precisely　tune　the　distance　between　the　AuNPs　becomes　shorter,　resulting　in　a　remarkable　amplification　of　electrochemiluminescence　(ECL)　signals.　Additionally,　differing　from　the　poor　stability　of　conventional　ECL,　uniform　dispersion　of　the　Ru(bpy)(3)(2+)　over　nanocomposite　hydrogel　significantly　enhanced　the　long　term　stability　of　ECL.
