A new colorimetric method for the detection of chemotherapeutic drug 6-mercaptopurine (6-MP) is developed based on controlling localized surface plasmon resonance (LSPR) of triangular silver nanoplates (AgNPs). The triangular AgNPs can be etched by trace amount of Cl− and transformed to a disc-like shape, accompanied by a blueshift of the corresponding LSPR absorption band. With the protective effect of 6-MP, the AgNPs are hardly or partly to be etched by Cl−, resulting in a reversed shift of LSPR. Based on a linear relationship between LSPR wavelength change and the concentration of 6-MP, a fast, visual and selective method for 6-MP assay is established. This method has been successfully applied to the detection of 6-MP in tablets.

A simple and facile preparation approach of gold-silver nanoframes is described based on triangular silver nanoplates. HAuCl4was used as etching agent and added to boiling nanoplates suspension under stirring. Especially, when different concentrations of HAuCl4was employed, various etching happened and corresponding morphology of gold-silver nanoframes were acquired. The properties of nanoframes were characterized by scanning electron microscopy (SEM) and UV-vis spectra. Then the nanoframes were self-assembled onto the silicon treated with APTMS and used as SERS substrates for detecting p-ATP molecules. The results indicated that nanoframes showed better SERS effects than nanoplates.
