Cellulose nanocrystals (CNCs), or nanocrystalline cellulose (NCC), are highly crystalline, rod-like nanoparticles. [6] [7] They are usually covered by negatively charged groups that render them colloidally stable in water. They are typically shorter than CNFs, with a typical length of 100 to 1000 nanometers. [8]
Cellulase is used in medicine as a treatment for phytobezoars, a form of cellulose bezoar found in the human stomach, and it has exhibited efficacy in degrading polymicrobial bacterial biofilms by hydrolyzing the β(1-4) glycosidic linkages within the structural, matrix exopolysaccharides of the extracellular polymeric substance (EPS). [19] [20]
Capsules formed from cellulose sulphate have been successfully used, showing safety and efficacy, in clinical and pre-clinical trials in both humans and animals, primarily as anti-cancer treatments, but also exploring possible uses for gene therapy or antibody therapies.
Nanomedicine is the medical application of nanotechnology. [1] Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines.
A nanocrystalline (NC) material is a polycrystalline material with a crystallite size of only a few nanometers. These materials fill the gap between amorphous materials without any long range order and conventional coarse-grained materials. Definitions vary, but nanocrystalline material is commonly defined as a crystallite (grain) size below ...
Polysaccharides and saccharides are used due to their non-toxicity and biodegradability. They are attractive to use as they resemble biological membranes. [8] The core of a nanocapsule is composed of an oil surfactant that is specifically selected to coordinate with the selected drug within the polymeric membrane.
Due to their high porosity and large surface area-to-volume ratio, nanofibers are widely used to construct scaffolds for biological applications. [1] [2] Major examples of natural polymers used in scaffold production are collagen, cellulose, silk fibroin, keratin, gelatin and polysaccharides such as chitosan and alginate.
As such, in recent times, cell therapy has been recognized as an important field in the treatment of human disease, [7] and investigations are ongoing in articular cartilage, [8] brain tissue, [9] [10] spine, [11] heart, [12] cancers, [13] etc. As a consequence cell therapy as a strategy has been attracting significant investments by commercial ...
