Inhalation of Titanium Dioxide Nanoparticles Impact on Lungs
Inhalation of Titanium Dioxide Nanoparticles Impact on Lungs
Titanium dioxide nanoparticles are commonly used in industry from paints and plastics, to food coloring and cosmetics. Worker who are dealing with the creation of these products are exposed to high levels of these nanoparticles and understanding their impact on human health is imperative. These nanoparticles interact with proteins in lungs, which create a protein corona, and they interact with immune system cells and lung tissue which can lead to inflammation.
Bacterial Electrophysiology
Bacterial Electrophysiology
Bacterial electrophysiology is the study of the dynamic response of the membrane potential on bacterial cells. My research has focused on external stimuli like blue light, ethanol, and silver ions. These external stimuli cause hyperpolarization in the bacterial cells and this change in membrane potential is correlated with slowed growth rates.
