      abstract     = {We propose a highly sensitive immunosensor based on the
                      Localized Surface Plasmon Resonance (LSPR) for
                      17β-estradiol (E2) quantification in water. E2 molecules
                      are recognized by polyclonal antibodies immobilized onto
                      gold nanoparticles (AuNPs) and act as linkers that cause
                      nanoparticles aggregation. This leads to the change in the
                      optical properties of the solution visible even by naked
                      eyes. The aggregates were characterized by Dynamic Light
                      Scattering (DLS) and Scanning Transmission Electron
                      Microscopy (STEM) that provided an accurate assessment of
                      the inter-particle distance. The finite-difference
                      time-domain (FDTD) method applied to a Mie problem like
                      workspace allowed us to describe the optical behaviour of
                      the AuNP aggregates with excellent agreement between the
                      experimental and numerical results. The limit of detection
                      (LOD), without any preconcentration step, is 3 pg/mL (11
                      pM), whereas the detection range extends over five decades
                      up to 105 pg/mL. The proposed E2 immunosensor was tested in
                      tap water, where no significant cross-reaction signal was
                      detected by similar molecules (testosterone, progesterone,
                      estrone and estriol). The device described here represents a
                      significant improvement of low E2 levels determination in
                      terms of affordability, time and measuring simplicity,
                      making it suitable for environmental applications.},
