Researchers can use it to search for molecular clues associated with cancer, investigate the chemical landscape of the brain or determine where a drug travels after it enters the body. Mass spectrometry imaging, or MSI, helps answer those questions by mapping where different molecules are located within tissue.","pubDate":"Tue, 27 Oct 2026 18:40:03 EDT","url":"https://phys.org/news/2026-10-simple-recipe-guesswork-mass-spectrometry.html"},"indexado":"2026-10-27T22:41:52.222Z"}}
