文摘

Silver nanorods (AgNRs) were embedded into polydimethylsiloxane (PDMS) for ultra-sensitive detection of trace amounts of pesticides. The embedded AgNRs layers show good adhesion onto the PDMS surface as shown by the scotch tape peeling test. The flexible nature of the substrate enables conformal contact with the surfaces under investigation leading to efficient sample collection.
