• substrate. It is clear from Table 1 that most studies regarding SERS detection of anionic analytes are reported in the millimolar concentration range. Particularly, the SERS spectrum of bilirubin [20] could be obtained at nanomolar concentration due to the resonance Raman supplementary enhancement mechanism

• 10.3762/bjnano.4.81 Abstract In recent years, nanotechnology has gained significant interest for applications in the medical field. In this regard, a utilization of the ZnO nanoparticles for the efficient degradation of bilirubin (BR) through photocatalysis was explored. BR is a water insoluble byproduct

• photocatalytic degradation and time-correlated single photon counting studies revealed that the defect-engineered ZnO nanoparticles that were obtained through post-annealing treatments led to an efficient decomposition of BR molecules that was enabled by Förster resonance energy transfer.
