“…The development of new fibers for use in healthcare textiles has increased rapidly over the last two or three decades, and is expected to expand even more. The use of natural fibers in medical applications goes back to ancient times and has recently become of great interest due to the fact that natural fibers are readily available and easily produced and because their molecular structure offers excellent potential as a matrix for the design of bioactive, biocompatible, and intelligent materials …”

Improvement of Chitosan Adsorption onto Cellulosic Fabrics by Plasma Treatment

Oxygen plasma treatment was applied in order to improve the adsorption of chitosan onto viscose fabric. Modification of the surface and adsorption of chitosan was monitored by determination of XPS spectra, determination of contact angles from rates of water imbibition, and conductometric titration. The plasma treatment resulted in hydrophilization of the surfaces through oxidation. The hydrophilic surfaces were stable for at least 24 h. The treatment also yielded binding sites that resulted in over 20% increase of the amount of chitosan adsorbed over that adsorbed on nontreated fabric. Layers of chitosan adsorbed after plasma treatment were substantially more active as antimicrobial agents than those on nontreated surfaces.

“…in different combinations and structural forms, 1,2 as well as different conventional chemical compounds, such as inorganic salts, phenols, formaldehyde derivatives, amines, etc., into/onto the fibrous /textile substrate. 3–5 Iodine is one of these chemical compounds, showing not only great antimicrobial, but also antioxidative properties. Based on the available evidence from clinical trials, iodine is an effective antiseptic agent showing neither the purported harmful effects nor a delay in the wound-healing process, particularly in chronic and burn wounds and other infections.…”

Adsorption of chitosan nanoparticles with embedded iodine was implemented onto pristine and oxidized cellulose viscose fabrics in order to introduce antimicrobial and antioxidative functionalization. The adsorption capacity, charging behavior and electrokinetic response of differently functionalized viscose at different pH values were analyzed by determining their zeta potential. Desorption studies, besides zeta potential measurements, were supported by polyelectrolyte titration. Finally, the antimicrobial properties were evaluated by the standard ASTM E2149 method, whilst antioxidative properties were determined by 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical cation decolorization assay. It was found that the oxidation of viscose fabrics further modified by chitosan–iodine nanoparticles dispersion was a very promising functionalization process, providing good coating stability along with antimicrobial and antioxidant properties.

“…Colorimetric detection of HNE using a rapid spot test to detect HNE levels on an immobilized enzymesubstrate-derivatized surface could be potentially used at the bed side or imbedded in the dressing design to measure protease levels and thus help control the pathology of protease ridden chronic wounds. The wound dressing designs for lowering HNE levels in the chronic wound have previously been shown (25). For this reason an approach for monitoring wound HNE levels in patients with chroinic wounds would enhance the efficiency of assessing the need to apply therapeutic modalities to lower HNE through sequestration or inhibition.…”

The design, preparation, and application of both immobilized enzymes and enzyme substrates on cotton fibers for biomedical and specialty applications, includes antibacterial fabrics, decontamination wipes, debridement and chronic wound dressing prototypes, and protease detection devices. The molecular design steps of enzyme and enzyme substrate cellulose conjugates is presented.Molecular models of lysozyme-and orgaonphosphorous hydrolase-cellulose conjugates are given as examples of assessing the utility of the biorationally designed fabrics. The chemistry of immobilzing the enzyme or enzyme substrate to the cotton fabric of choice, employs use of crosslinking agents for either aqueous or organic coupling reactions.Assays for assessment bioconjugate activity is pivotal to optimizing the development of the immobilized enzyme or substrate as a product.U.S.
