Interaction of gold nanoparticles with mitochondria

Colloids and Surfaces B: Biointerfaces, 2009
Mitochondrion is one of the most important organelles in cells with several vital responsibilities. The consequence of a deficiency in the function of mitochondrion could result with the wide range of diseases and disorders. In this study, we investigated the feasibility of utilizing surface-enhanced Raman scattering (SERS) to understand the mode of ...
