“…all the samples showed the loss in weight in the range of 2.99-3.58 % for oxidation with 0.2 % NaIO 4 and 3.2-3.99 % for oxidation with 0.4 % NaIO 4 . These results are very similar to the results reported by Calvini [9] and Nikolic [4] for cotton, slightly lower than the weight loss values (4.47-5.04 %) obtained for sodium periodate oxidized viscose samples [27] and considerably lower when compared to the weight loss values (up to 21 %) determined for lyocell fibers oxidized with KIO 4 under similar conditions [5]. According to the presented results, sodium periodate causes only slight damage to the cellulose in the conditions applied in the experiment.…”

Oxidized cellulose has a long history of safe and effective use in medical applications. In this paper, research has been directed towards obtaining hormone-active cellulose fibers in the form of an artificial insulin depot, and examination of its biocompatibility regarding cytotoxicity, sensitization, and irritation. The procedure of obtaining the fibrous insulin depot is based on the modification of cotton fibers with sodium periodate, followed by chemisorption of insulin from insulin aqueous solutions. In order to optimize the insulin chemisorption process, the influence of the fiber structure parameters, i.e. the aldehyde group content and iodine sorption value (ISV) on the chemisorption capacity was examined. The obtained artificial depot, containing ≈55 mg insulin/g of fibers, has been characterized in vitro by investigation of the desorption kinetics of the insulin from the fibrous depot. It has been shown that insulin is controllably released in quantities of 1.3-1.6 mg of insulin during 24 hours, in the course of 20 days. The results of biocompatibility tests have shown that the examined artificial depot neither shows irritating effects nor provokes sensitizing or cytotoxic effects. Therefore, these materials are acceptable for use in a direct contact with tissue of a living organism.

Enzymes are excellent catalysts in many applications due to their biocompatibility, low energy consumption, unique selectivity, and mild reaction condition. However, some disadvantages limit the usage of enzymes in end uses, such as low stabilities and difficult recovery. In order to overcome these disadvantages, enzyme immobilization was developed. Among various kinds of substrates for attaching enzyme, cellulose and its derivatives are one of the ideal matrixes because they are low cost, nontoxic, renewable, biodegradable, and biocompatible. In this review, we summarize recent progress in the research of enzyme immobilization on cellulose matrixes.

Environmental concerns, such as global warming caused by fossil burning, have drawn attention from people and make it necessary to develop photothermal conversion materials that can utilize clean and renewable solar energy. In this study, a novel viscose fiber with photothermal conversion ability was prepared by adding graphene oxide (GO) to viscose solution before wet spinning process. The light-to-heat conversion property of modified fibers was measured by a self-assembly structure. The results indicate that compared with pure viscose sample (ΔT =~30.8 C), the viscose fabric with 4 wt% GO showed larger temperature rise (ΔT =~112 C) within the same exposure time under infrared light. Moreover, it can be verified from ultraviolet-visible-nearinfrared spectroscopy and heat conduction property measurements that both optical absorption and thermal conductivity of GO-viscose fibers were enhanced significantly. Additionally, scanning electron microscope, energy disperse spectroscopy, Fourier transform infrared spectrometer, and thermogravimetric were used to characterize basic features of the composite fiber. Furthermore, It was observed that the doping of low concentration of GO has little effect on fiber strength and stretchability. Consequently, the modified GO-viscose composite is a promising photothermal conversion material for various applications involving solar energy collection and heat supply for architecture.
