  • Title: Optical pico-biosensing of lead using plasmonic gold nanoparticles and a cationic peptide-based aptasensor.
    Author: Solra M, Bala R, Wangoo N, Soni GK, Kumar M, Sharma RK.
    Journal: Chem Commun (Camb); 2019 Dec 19; 56(2):289-292. PubMed ID: 31808471.
    Abstract:
    A novel biosensor for the rapid detection of lead ions employing the optical properties of AuNPs, a lead-specific aptamer and a cationic peptide has been demonstrated. The limit of detection of the biosensor was 98.7 pM, the lowest so far obtained using colorimetry.
