TL;DR: In this paper, a review discusses the various attempts reported on solving this problem from the point of view of the chemistry and the structure of these polymers highlighting the drawbacks and advantages of each method and proposes that based on considerations of structure-property relations, it is possible to obtain chitin fibers with improved strength by making use of their nanostructures and/or mesophase properties of chitins.

TL;DR: The work of Joseph Lister and Louis Pasteur established a sound basis for the management of infection by identifying the cause and developing methods for preventing it and the antiseptic technique was followed shortly by the "aseptic technique," in which a sterile environment was used to prevent the onset of infection.

TL;DR: The usage of nanoparticles, synthesized with Z. officinale extract, as vectors for the applications in drug delivery, gene delivery or as biosensors, where a direct contact with blood occurs is justified.

TL;DR: A new method for the preparation of porous spherical hydroxyapatite granules is reported and its application towards delivery of macromolecules or protein drugs is discussed utilizing human serum albumin (HSA) as a model protein.

TL;DR: Le chitosan, un polysaccharide presentant des caracteristiques structurales similaires au glycosylamino glycan, a ete etudie en vue d'applications biomedicales diverses comprenant les membranes d'hemodialyse, la peau artificielle ou les pansements bioactifs, les excipients din les systemes d'administration, les matrices dans les colonnes de perfusion and un materiau potentiellement hemost
