  • Title: Ultrasensitive aptamer-based SERS detection of PSAs by heterogeneous satellite nanoassemblies.
    Author: Ma W, Yin H, Xu L, Wu X, Kuang H, Wang L, Xu C.
    Journal: Chem Commun (Camb); 2014 Sep 04; 50(68):9737-40. PubMed ID: 25020000.
    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.
