    Sustainable Lignocellulosic Nanomaterials as a Platform for the Development of Anti-Biofouling Surfaces

    Abstract

    Promoting proper access to safe and clean water is one of the biggest challenges of this century. Expanding world population, increasing food demand, drought, and climate change are some of the aggravators of freshwater scarcity. Carbon-based nanomaterials (e.g., graphene oxide and carbon nanotubes) have been extensively used for water purification applications. However, the production of these carbon-based nanomaterials requires toxic chemicals or complicated and time-consuming processes. In addition, all these materials present drawbacks that may limit their scalability or pose environmental risks. Understanding the current demand for more sustainable materials, our group at UF has studied the applicability of lignocellulosic nanomaterials in the context of water purification. Our attention has been focused on cellulose nanocrystals (CNCs), which are very hydrophilic and nanotube-like nanoparticles produced from plant-containing cellulose via simple aqueous treatments. CNCs are highly crystalline, non-leachable, and have a high surface area and tunable surface chemistry, making them promising nanomaterials for several applications in water treatment. At this presentation, I will discuss the intrinsic antimicrobial properties of CNCs, highlighting possible mechanisms of action. Also, I will show the potential application of CNCs as anti-biofouling agents. By taking advantage of their surface chemistry, CNCs can be chemically bound to the surface of thin-film composite membranes to impart biofouling resistance. Although biofouling is an inevitable truth, the use of nanomaterials as antimicrobial coatings can help to develop alternative therapies and contribute to overcoming the inefficiencies caused by biofouling formation.

    Bio

    Dr. Faria is a tenure-track assistant professor at the Department of Environmental Engineering Sciences at the University of Florida (UF). Before joining (UF), she was a former postdoctoral fellow in the Department of Chemical and Environmental Engineering at Yale University under the supervision of Prof. Menachem Elimelech. Her research interests include the development of engineered nanomaterials (ENMs) to improve water treatment and water quality monitoring. Over her research career, she has published 29 peer-reviewed articles in highly ranked journals, two patents, two book chapters, and has participated in numerous conferences. She believes that a multidisciplinary effort that integrates the areas of chemistry, biology, computing, and engineering can help us find innovative solutions to environmental problems.
