One pod synthesis of single crystal silver nanowires for selective detection of Pb(II)

With tannin as both reducing and stabilising agents, high yield single-crystalline silver (Ag) nanowires were synthesised in a simple solution system at 45-55°C. No additional capping or co-reduction agent was required. The length of the Ag nanowires could be up to several tens of micrometres and the average diameter was 50 nm. By adjusting the temperature and pH values of the reaction system, nan...
