7_23/2011Nanostructure Synthesis: On-Chip Screening of Experimental Conditions for the Synthesis of Noble-Metal Nanostructures with Different Morphologies (Small 23/2011)

The cover picture shows an on-chip approach to the rapid screening of experimental conditions pivotal to the production of nanostructures with different morphologies. By taking advantages of microfluidics, this approach uses an array of reactors containing solutions with a 1D or 2D gradient in reagent concentration, pH value, or reaction temperature. In the proof-of-concept experiments, the parameters needed for the production of Au and Pd nanostructures with various morphologies are quickly identified. In principle, this approach can be extended to other systems for rapid screening and optimization of experimental conditions involved in the syntheses of different types of nanostructures. For more information, please read the Full Paper “On-Chip Screening of Experimental Conditions for the Synthesis of Noble-Metal Nanostructures with Different Morphologies” by Y. Xia and co-workers, beginning on page 3308.
