The ubiquitous nature of plastic pollution in our environment is an alarming concern. The breakdown of plastics into smaller sizes, ranging from micro- to nano-sized material, raises concerns about their toxicity to the environment and humans. The impact of nanoplastics, which are a thousand times smaller than microplastics on fish, marine life and human life is under intense investigation, however, mitigating options are quite limited.

A team of researchers led by Chemical Engineering Professor Tizazu Mekonnen, at the University of Waterloo, have leveraged their expertise in polymer engineering to tackle this critical challenge. Mekonnen’s research is in polymer sustainability, and it endeavours to reduce the carbon footprint of the plastics industry.

Nanotechnology Engineering alumna CT Murphy (BASc ’23) created CELLECT, a new start-up which aims to improve access to cervical cancer and HPV screening. CELLECT's technology uses nanomaterials in menstrual products to diagnose HPV and cervical cancer using menstrual blood, potentially eliminating the need for Pap smears.

Murphy’s fourth-year design project served as inspiration for their Masters thesis under the supervision of Chemical Engineering professor Marc Aucoin. Murphy was awarded the Waterloo Institute for Nanotechnology (WIN)-Velocity scholarship for the project. They also received funding from Velocity’s Up Start Program and Cornerstone Program.

Researchers at the University of Waterloo have developed a unique technique to create the Janus structures in liquids. Chemical Engineering Professor Milad Kamkar in collaboration with the University of British Columbia leads the first research to achieve this duality with liquids.

This breakthrough can be utilized in a multitude of applications. It could be used in environmental remediation, to clean up oil spills in water or for wastewater treatment. One side could be treated with super absorbent nanomaterial to soak up the oil, while the other side might contain catalysts to degrade the pollution.

Dr. Elisabeth Prince is a professor in the Department of Chemical Engineering who is working on a solution to the challenge of non-degradable and non-recyclable plastics. Her innovative research in advanced materials has the potential to make a significant impact on sustainability and environmental remediation. It also supports Canada's aim of achieving zero plastic waste by 2030.

Professor Elisabeth Prince, along with an interdisciplinary team of researchers from the University of Toronto and Duke University, have developed hydrogels that imitate human tissue. The synthetic material is made from cellulose nanocrystals, which are extracted from wood pulp. The material is designed to mimic the fibrous nanostructures and properties of human tissues, thereby replicating its unique mechanical properties.
