In 2019, many interesting and innovative research articles about chitosan and chitosan derivatives were published. In this article we present you an overview which chitosan reserach topics were important in 2019.

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.

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.

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.
