Technique:
Optical enhanced darkfield microscopy was performed on lung lymph node tissue of a rat following inhalation exposure to alumina nanoparticles. Tissues were stained with standard hematoxylin and eosin (H&E) histological stains and imaged using a CytoViva enhanced darkfield microscope.
Description:
The rapid growth and projected acceleration of nanotechnology creates urgency in understanding, predicting, and managing the health risks associated with workplace exposure to engineered nanomaterials. People may be unintentionally exposed to nanomaterials by breathing them in or touching them. Our group seeks to understand how the body reacts to the metal oxide nanoparticles used during semiconductor manufacturing. By using rats as a model, we hope to discover where the nanoparticles accumulate within the body and better understand associated immune responses.
