Description Polylactic acid is a thermoplastic aliphatic polyester. The lactic acid or lactide required for the production of polylactic acid can be obtained by fermentation, dehydration and purification of renewable resources. The obtained polylactic acid generally has good mechanical and processing properties, and the polylactic acid product can be quickly discarded in various ways. degradation.
Application They adopt nanometer-scale dimensions, and can be ideal candidates for drug delivery, gene transfection applications.
Features And Benefits Low toxicity and good biocompatibility.
