title: Ultrasensitive aptamer-based SERS detection of PSAs by heterogeneous satellite nanoassemblies.
abstract: An ultrasensitive method for surface enhanced Raman scattering (SERS) detection of prostate-specific antigens (PSAs) was established based on the aptamer directed core-satellite nanostructures. A limit of detection (LOD) of 4.8 aM for PSA was obtained.
