摘要：
Lead ions in solution interact strongly with human blood serum albumin forming clusters and modifying electronic properties of albumin molecules. We experimentally demonstrate that this interaction can be detected at pM concentrations of lead in solution. The structural and electronic modifications of albumin were observed using Raman, light scattering, fluorescence, and circular dichroism absorption spectroscopies.
