Polysaccharide polymer has advantageous applications in bio-field, engineering and food industry because of remarkable properties such as biocompatibility and biodegradability. In this review, we describe the pectin polysaccharide nanomaterials and how the chemistry of pectin works in the development of nanoparticles and nanowires fabrication. We also discussed the recent advances of pectin-based nanomaterials including their synthesis strategies and applications. This pectin nanoscience review can be more useful to gain insight into the pectin nanochemistry for the nanosciences of engineering.
