An optical biomodule for detecting a disease specific biomarker, utilizing an enhanced light emission due to integration of one or more three-dimensional (3-D) protruded structures in a fluidic container (which includes one or more materials), upon chemical binding of a disease specific biomarker binder (which includes a first segment coupled with a first fluorophore and a second segment coupled with a second fluorophore) with its corresponding disease specific biomarker is disclosed. Furthermore, the disease specific biomarker binder may include a synthetic biological logic circuit/gate. Furthermore, the three-dimensional (3-D) protruded structure can be coupled with a photonic crystal or a metamaterial (hyperbolic metamaterial/metamaterial of Epsilon-Near-Zero (ENZ)) of a suitable wavelength range.
