A multi-chromophore virus particle is constructed by covalent binding of chromophores and provides super-radiant behavior. A virus-enabled targeted vector is provided for imaging with qualitatively different optical emission properties from state-of-the-art agents. Bright emission is obtained through quantum coherence, which in turn is facilitated by the symmetry of the virus shell. In an exemplary embodiment the targeted vector is used in laser-guided surgery, specifically for the treatment of in brain cancer.
