Molecular Jackhammers & Near-IR Light Kill Cancer Cells

  Researchers have identified a new cancer treatment approach using molecules dubbed molecular jackhammers (MJHs), which are aminocyanines capable of mechanically disrupting cancer cell membranes through vibronic-driven action (VDA) when activated by near-infrared light. Key Concept: Vibronic-Driven Action VDA operates through subpicosecond whole-molecule vibrations of aminocyanines bound to cell membranes, initiated by targeted light exposure [...]
