文摘
- •
The silver decahedral nanoparticles (Ag10NPs) are very stable in NaCl.
- •
The functionalization of Ag10NPs with ssDNA is rapid, just 2 h.
- •
The prepared colorimetric sensor based on aptamer-Ag10NPs is highly sensitive and selective.
- •
The sensor can be applied in detection of PDGF-BB in serum.
