Researchers at Aalto University Target Nanoporous (Preparation and Enzymatic Degradation of Porous Crosslinked Polylactides of Biomass Origin)

August 15, 2014

By a News Reporter-Staff News Editor at Science Letter -- A new study on Nanoporous is now available. According to news reporting from Aalto, Finland, by NewsRx journalists, research stated, "To understand the enzymatic degradation behavior of crosslinked polylactide (PLA), the preparation and enzymatic degradation of both thermoplastic (linear) and crosslinked PLAs that have pore structures with different dimensions were carried out."

The news correspondents obtained a quote from the research from Aalto University, "The porous structures of the linear PLA samples were of micro and nanoporous nature, and prepared by batch foaming with supercritical CO2 and compared with the porous structures of crosslinked PLA (Lait-X) created by the salt leaching method. The surface and cross-sectional morphologies of the porous structures were investigated by using scanning electron microscopy."

According to the news reporters, the research concluded: "The morphological analysis of porous Lait-X showed a rapid loss of physical features within 120 h of exposure to proteinase-K enzymatic degradation at 37 degrees C. Due to the higher affinity for water, enhanced enzymatic activity as compared to the linear PLA porous structures in the micro and nanoporous range was observed."
