27 April 2017 - Bioinspired films to understand the nanomechanical properties of plant cell walls

Atomic force microscopy (AFM) allows observation and measurement of physical and mechanical properties of plant cell walls at nanoscale level.

Through a collaboration between FARE and the Research in Nanosciences Laboratory (LRN) of URCA, we have designed bioinspired lignocellulosic films with increasing complexity to understand the mechanical properties of lignocellulosic biomass at nanometric scale. AFM measurements of the indentation moduli performed on lignified cell wall (A) compared with those performed on the corresponding lignocellulosic films (B) clearly show the importance of the lignin in the mechanical properties of cell walls (C). Through this strategy, we envision a wide application of bioinspired systems in future studies of the relationship between physical, chemical and mechanical properties of lignocelluloses at nanometric scale.
