Atomic vacancies of molybdenum disulfide nanoparticles stimulate mitochondrial biogenesis.

Diminished mitochondrial function underlies many rare inborn errors of energy metabolism and contributes to more common age-associated metabolic and neurodegenerative disorders. Thus, boosting mitochondrial biogenesis has been proposed as a potential therapeutic approach for these diseases; however, currently we have a limited arsenal of compounds that can stimulate mitochondrial function. In this study, we designed molybdenum disulfide (MoS) nanoflowers with predefined atomic vacancies that are fabricated by self-assembly of individual two-dimensional MoS nanosheets.
