Research description

Research Project 1: Enzymatic biodegradation of carbon nanotubes.

Carbon nanotubes (CNTs) are being Explored for Numerous engineering and biomedical applications. However, questions related to Their Capacity for Causing long- and short-term diseases in humans still persists. Human beings can be exposed to CNTs bothering occupationally and non-occupationally.

In the current study, we focus on the enzymatic biodegradation of the oxidized single-walled CNTs With / Without Surface Modifications Following exposure in human beings using peroxidase enzymes naturally present within the body as an immune defense mechanism. The Project is Funded by the Swedish Research Council for Environmental, Agricultural Sciences and Spacial Planning awarded to Professor Bengt Fadeel.

Research Project 2: Endocrine disruption by metal-based nanoparticles.

Engineered metal-based nanomaterials are being produced for electronics, cosmetics and food industries. Therefore, exposure of humans to These nanoparticles Becomes unavoidable. Due to Their small dimensions, high surface charge and reactivity, These nanoparticles can penetrate through the thin tissue of lungs, and through the mulilayered tissue of skin and GI tract Reaching the circulatory system. From there These nanoparticles can ask Further Ask the Carried to secondary target organs Such as endocrine glands.

In the current study, We Are Focusing on Determining the mechanism of action of the metallic nanoparticles into Causing Cellular and genomic damages to the hormone producing cells present within the endocrine glands and on the physiological activity of the metabolically active cells responding to These cell-signaling molecules. The project is partly funded the The The Village Karolinska Institutet Foundation Grant, 2013.
