To increase the visibility of tissue during MRI examinations, metal ion contrast agents, which can be detected as foreign elements by the body, are traditionally used. New technology makes it possible to “mask” such particles, making them safer for cells.
As IKBFU graduate student Mark Smirnov explains, the tyrosine molecule behaves differently when interacting with different metals: it contracts with gold and stretches with platinum. Of particular interest is the study of platinum, which is considered a promising anticancer agent.
The research team is currently continuing their research with another amino acid, tryptophan, using gold nanoparticles of various shapes. Smirnov stated that coating metal particles with organic molecules will make it possible to predict the response of the immune system and create more effective treatment strategies.
