  • Extraction of chitin from insects

    Published on

    Commercial extraction of chitin is mainly from the shells of crustaceans such as snow crabs. Fungi and insects are alternative sources of chitin, which are poorly usable so far. The expansion of insect farming for animal feed production in recent years has increased the availability of insect biomass. In the following, we present a review that provides an overview of recently published studies on the extraction of chitin from insects and its conversion to chitosan.

  • Chitosan for pulmonary applications

    Published on

    Chitosan is a promising drug delivery system for pulmonary applications and is therefore of particular interest for vaccine development in the Corona Pandemic. The biodegradable and biocompatible polymer's mucoadhesive, permeation-increasing and site-/cell-specific properties are useful in this context. Nanocarriers based on various microencapsulation and micro-nano mixing systems have already been developed. The aerodynamic character is important to enable efficient pulmonary aerosol formation and inhalation. In this article we present research on chitosan as pulmonary particulate anti-infective drug carrier.

  • 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.

  • Chitosan in biocompatible fuel cells

    Published on

    Chitosan is employed in many domains. Besides medical areas like e.g. as support in wound healing or in tissue engineering chitosan can also be applied in the fields of food technology and water management. Thanks to scientists of the faculty of Microsystems Technic at the Univesity of Stuttgart, chitosan might soon become part of biocompatible fuel cells.

  • Chitosan as basis of self-healing coatings

    Published on

    Scientist at the Mississippi South University in Hattiesburg succeded a spectacular development - a self-reparing material when exposed to ultraviolet light. Prof. Marek Urban and Ph.D. student Biswajit Ghosh were researching on a coating, which main components are chitosan and oxetan. From their point of view this priniciple can be of greatest importance for many matrials.

  • 150 Years Chitosan - an all-round-talent is discovered

    Published on

    150 Years ago C. Rouget discovered the biopolymer chitosan when cooking chitin in a base. Ever since, the interest in this polymer is increasing constantly. On the one hand new application fields are developed over and over again. On the other hand the primary material chitin is a renewable resource, which is generated as by-product in huge annual quantities in food-industry.

  • American start-up for wound care solutions

    Published on

    American start-up for chitosan wound care solutions PhD students in Maryland (University of Maryland and Robert H. Smith School of Business) found their own start-up to develop blood-clotting products. Already two products are in a development phase. A surgical spray and a sponge, both based on chitosan.

  • Chitosan in Tissue Engineering Applications

    Published on

    Dr. Thomas Freier

    Tissue engineering is a rapidly growing interdisciplinary field of research focused on the development of vital autologous tissue through the use of a combination of biomaterials, cells, and bioactive molecules, for the purposes of repairing damaged or diseased tissue and organs. The future tissue engineering market potential has been estimated at 70 billion Euro. Due to its biocompatibility and biodegradability, together with its specific interactions with components of the extracellular matrix and growth factors, chitosan has emerged as exceptionally promising material for various tissue engineering applications, including skin, nerve, bone, and cartilage repair applications.

  • Characterization of Chitosans using Asymmetrical Flow Field-Flow Fractionation and Multi-Angle Light Scattering

    Published on

    Christian Augsten, Karsten Mäder

    Flow Field-Flow Fractionation (Flow-FFF) is a powerful tool to separate molecules and particles in a range from 103 to 107Da and particles of nanometric size up to a few micrometers [1]. By coupling FFF to Multi-angle light scattering (MALS) it is possible to determine absolute molar masses (M) of molecules and to verify their aggregation. For macromolecules of an appropriate size the radius of gyration (rg) can be achieved [2]. The aim of our study was to investigate various chitosan types by applying Flow-FFF and MALS to their aqueous solutions.
