Cation-Selective Microcontact Printing Based on Surface-Molecular-Imprinted Layer-by-Layer Films

Cation‐selective microcontact printing (μCP) is achieved by the combination of a surface‐molecular‐imprinted layer‐by‐layer (SMILbL) films with μCP. The SMILbL film greatly enhances the charge selectivity of the imprinted‐film‐modified stamp and the PDMS stamp modified by the SMILbL film shows a hig...

Description
Summary:Cation‐selective microcontact printing (μCP) is achieved by the combination of a surface‐molecular‐imprinted layer‐by‐layer (SMILbL) films with μCP. The SMILbL film greatly enhances the charge selectivity of the imprinted‐film‐modified stamp and the PDMS stamp modified by the SMILbL film shows a high selectivity to multiply charged cations. The SMILbL‐film‐modified stamp can also be used for selective transfer of single‐charged chemical species.
