We describe herein, a novel method for the synthesis of anisotropic gold and palladium nanoparticles through a simple galvanic replacement reaction across a semi-permeable dialysis membrane. The control over the reaction kinetics achieved by the presence of membrane enables one to tune the bimetal composition, particle porosity and morphology. Rapid outward diffusion of silver ions generated from the sacrificial silver nanoparticles even at room temperatures prevents the precipitation of high quantities of silver chloride, thereby circumventing the need for product purification. The porous anisotropic nanostructures have potential applications in catalysis, cell imaging and therapeutics.</p>10aAg/Pd Nanostructures10aAnisotropic Nanoparticles10aDialysis10aGalvanic Replacement10aPorous nanostructures10aSilver Nanotriangles10aSilver Nanowires10aTransmetallation1 aShukla, Sourabh1 aPasricha, Renu1 aSastry, Murali  uhttps://library.ncl.res.in/content/porous-anisotropic-metal-nanostructures-through-controlled-transmetallation-across-0
