Interfacial Technologies Characterization Laboratory

McMaster University, Hamilton, Ontario
What the facility does

Develop Bioactive paper products, measure nanoparticle and colloidal particle properties.

Areas of expertise

The SENTINEL Bioactive Paper Network is an initiative of NSERC and the Canadian paper industry to develop products that will improve human health in Canada and around the world. SENTINEL is working to create critical technology platforms that will lead to the commercial-scale production of bioactive papers that can detect, capture and deactivate water-borne and airborne pathogens.

Research services

Measures colloidal attachment to surfaces, monitors adsorption kinetics in real time, characterizes the interaction between a surface and a soluble species
