In the relentless pursuit of combating cancer, a transformative discovery emerges from a collaborative effort among leading institutions. Researchers from Rice University, Texas A&M University, and the University of Texas have unlocked a pioneering technique utilizing molecules’ unique vibrational properties when exposed to light, effectively targeting and destroying cancer cells.
The groundbreaking method revolves around the synchronized vibrations of atoms within a specific dye molecule, known as a plasmon, induced by near-infrared light. This stimulation causes the cell membranes of cancerous entities to rupture. Published in Nature Chemistry, the research showcased a staggering 99% efficacy against human melanoma cell cultures, with half of the melanoma-afflicted mice witnessing complete remission post-treatment.
James Tour, a distinguished chemist from Rice University, elucidated the innovation, dubbing it “molecular jackhammers.” Drawing distinctions from prior nanoscale drills, these molecular entities operate at unparalleled speeds, exceeding Feringa-type motors’ capabilities by over a million-fold. Crucially, their activation via near-infrared light ensures deeper tissue penetration—reaching up to 10 centimeters within the human body without causing harm, a monumental leap from the mere half-centimeter depth achievable with visible light. This advancement underscores a transformative stride in oncological research and treatment methodologies.
