In this work we propose epsilon-near-zero (ENZ) nanoparticles formed of metal and dielectric bilayers and employ the effective-medium approach for multilayered nanospheres to study their optical response. We obtain a passive tunable ENZ region by varying the radii of the proposed bilayer nanospheres, ranging from visible to near IR. In addition, we present the absorption and scattering cross section of ENZ nanoparticles using open-source transfer-matrix-based software (stratify). The proposed ENZ nanoparticle is envisioned to be experimentally realized using chemical synthesis techniques.
