摘要：

Using atomic force microscopy the morphology of 1 and 2 % sodium hyaluronate solutions matrix with low molecular weight (LM) and high molecular weight (HM) hyaluronic acid (HA) fabricated by bioenzymatic synthesis was evaluated. The presence of a proteoglycan aggregate with processes of the core protein in the absence of sulfated glycosaminoglycans was established. The effect of irradiation with a light flux on the ordering of the HA matrix was observed. Intermolecular consolidation of high molecular HA was established. The elastic modulus of the matrix with LM and HM HA has also been determined.
