Nanotechnology also provides researchers with valuable insights into drug mechanisms by enabling them to observe how drugs interact with biological systems on a cellular level. Fluorescent nanoparticles, for example, are used to track drug penetration, accumulation, and movement across cellular structures in in vitro models such as organoids and organ-on-a-chip systems. By visualizing these interactions, researchers gain a clearer understanding of how drugs are metabolized, how they cross biological barriers, and how they reach their targets, providing critical data for optimizing drug formulations.
In organ-on-a-chip models, fluorescent nanoparticles help researchers examine the dynamics of drug distribution and evaluate the effects of specific drugs on various cell types. This approach reveals important information about a drug’s behavior within the human body, from metabolism to tissue penetration and interaction with targeted cells. This mechanistic understanding is invaluable for developing new therapies for complex diseases, as it helps ensure that drugs are optimized for both efficacy and safety.
