Resumen:
Quantum dots multifunctionalized with the amyloid protein α-synuclein act at nanomolar concentrations as very potent inducers of the aggregation of micromolar−millimolar bulk concentrations of the protein in vitro and in cells. Fibrillation in live cells, a process diagnostic of Parkinson¬ís disease, is accelerated up to 15-fold with only 100 nanoparticles. The combination with a tetracysteine-tagged form of α-synuclein specific for fluorogenic biarsenicals constitutes a very sensitive system for studying pathological amyloid formation in cells.
