Application of a magnetic biosensor based on novel cracker-shaped noble metal nanoparticles in dual-modal multidimensional detection of bladder cancer urinary biomarker HAase.
Herein, a novel noble-metal nanomaterial in the shape of a cracker (AuAgPt NTCs) was synthesized. The nanoparticles exhibit outstanding Surface-enhanced Raman spectroscopy (SERS) performance (enhancement factor: 1.09 × 107) due to the tip effect of the triangular structure and edge protrusion, and plasmonic coupling fr...
