Nanomaterials in the environment:

Nano-scale materials are on the order of 1-100 nm in size and have applications in a wide range of products and industries including electronics, medicine, agriculture, oil and gas production, and environmental remediation. Our team is working on:

Nanoplastic and microplastic fate, transformations and toxicity in aquatic and terrestrial environments
Synthesis of new nanomaterials using green (sustainable) chemistries and processes
Development of nanotechnologies for water and soil remediation
Nanomaterial toxicity at different levels of biological organization (cell membranes, whole cell and whole organism)
