Gold nanoparticles with chitosan

Published on

Tags: nanoparticles, cancer, Gold

There are many potential applications of gold nanoparticles in medicine. Gold nanoparticles are already being used in diagnostics, as in pregnancy or HIV tests [1]. Research on the use as a contrast agent for the localization of cancer cells and as a drug delivery system for targeted release at site of action. The surface properties of gold are optimal for functionalization, e.g. with chitosan.

Wound treatment with chitosan

Published on

The healing process of a wound injury follows the steps of hemostasis, inflammation, cell proliferation, and regeneration until complete healing of the damaged tissue. In chronic wounds, the progress of these steps is disturbed, leaving the wounds inflamed for a long time. In an aging society with bad health habits (poor diet, little exercise), the number of chronic wounds is going to increase. Therefore, the research on materials that improve wound healing is important. The publications presented below are devoted to research about chitosan-based materials for the treatment of chronic wounds.

Supporting the regeneration of nerve cells with chitosan

Published on

Tags: Hydrogel, Regeneration, spinal cord

Worldwide, about 2.5 million people live with the consequences of a traumatic spinal cord injury. At the injured site formation of glia scar tissue prevents the regeneration of nerve cells. To date, complete functional recovery of the spinal cord is impossible, also because the cascade of events that takes place at the injured site is not fully understood yet.

Recombinant factor C assay for detection of bacterial endotoxins in chitosan

Published on

Tags: chitosan, rFC, recombinant factor C, endotoxin

Testing for bacterial endotoxins with recombinant factor C might be included as a new general chapter in the European Pharmacopoeia. The European Pharmacopoeia has called for public consultation on the creation of a new General Chapter (2.6.32). In 2016, the Pharm. Eur. referred the rFC test as an alternative to Limulus amebocyte lysate (LAL) in Guidelines for using the test for bacterial endotoxins (Supplement 8.8 Chapter 5.1.10). The next step would be a separate chapter on testing for bacterial endotoxins using the rFC assay.
