Download or read book Multi functional Thermoresponsive Hydrogel and Application on Textile for Skin and Wound Care written by Xiaowen Wang and published by . This book was released on 2017 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis presented a general and effective route to the synthesis of thermoresponsive hydrogels based on poly(ethylene glycol)-poly(e-caprolactone)-poly(ethylene glycol) (PEG-PCL-PEG), as well as the antibacterial modification of the PEG-PCL-PEG block copolymers through quaternization using quaternary ammonium salts (QAS). The study subsequently made use of the synthesized functional hydrogels for the fabrication of smart textile-based materials by a simple coating method, which can be used as a functional complex dressing for skin and wound care. The study primarily includes three research systems: (i) Design, synthesis and characterization of PEG-PCL-PEG hydrogel through coupling PEG and PCL with a chemical linker hexamethylene diisocyanate (HMDI) The as-obtained amphiphilic block copolymers-based hydrogel had non-cytotoxicity and showed a thermosemsitive sol-gel-sol transition behavior. The chemical structure of the synthesized block copolymers was confirmed by FTIR and 1H-NMR spectra. The surface morphology, the mechanism of the sol-gel transition behavior, and the in vitro drug release performance of the thermoresponsive hydrogel were investigated in detail through various characterization analyses. (ii) Synthesis, characterization and evaluation of a PEG-PCL-QAS-PCL-PEG antibacterial hydrogel with QAS as an antibacterial modification agent

Download or read book Multifunctional Enzymatically generated Hydrogel Platforms for Chronic Wound Application written by Ivaylo Stefanov Stefanov and published by . This book was released on 2019 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic wounds became burdensome problem of worldwide healthcare systems, along with the increased elderly population, which is the most vulnerable risk group, predisposed to their development. Chronic wounds represent a "silent epidemic" that affect a large fraction of the population and are often regarded as a comorbid condition. Statistical surveys indicated that 1-2 % of the population in developed countries will suffer from chronic wounds during their lifetime.Contemporary clinical treatment involves a combination of techniques and procedures aiming at eradication of wound chronicity and switching the biochemical entities to normal wound healing. In this regard, wound dressings have been affirmed and widely accepted as integral part of wound healing therapies. Wound care, by using dressings dates from ancient times, when for instance ancient egyptians applied and arranged bandages. Nowadays, the market is dominated by dressings, which only function besides a simple physical barrier is to balance the wound moisture by either absorbing excess exudates or providing moisture environment. However, the multifactorial nature of chronic wounds often renders this single-factor directed therapy as low or non-effective, aggravating the patient outcome. Thus, the demands for expanding the treatment options to more effective therapy brought about the development of bioactive dressings. These dressings should not only protect the wound and control the wound moisture, but also interact with various adverse wound constituents, modulating their bio-activities in favor of healing.Materials with inherent wound healing features are highly desireable and more attention to such materials among the research communities has lead to the design of wound dressings with improved characteristics. However, amongst the myriad novel dressings synthesized, there is still lack of universal dressing with a panel of features able to address most of the devastating chronic wound constituents. The lack of such on-market dressing, lead to huge economical burden of the healthcare systems, holding significant part of their budgets. Development of universal multifunctional dressing, appropriate for management of many types of chronic wounds will boost the health systems to minimize the costs and improve the quality of patient's life.This thesis develops multifunctional biopolymer-based hydrogel materials as a bioactive platform with appropriate exploitation characteristics for treatment of chronic wound. To this end, hydrogels were developed by using environmentally benign approach, based on enzymatic reactions. Intrinsically bioactive biopolymer chitosan which served as a matrix, was modified with thiol groups and further in situ enzymatically crosslinked with two different natural polyphenols. The incorporated in the biopolymer matrix polyphenols, exhibited dual role on the hydrogel performance by providing: 1) structural integrity by crosslinking the biopolymer chains; 2) bioactive features, through interaction with major chronic wound factors. The multifunctionality of the obtained materials in the treatment of chronic wounds was evaluated by in-vitro and ex-vivo experiments with chronic wound exudates. The hydrogels exhibited beneficial for wound healing properties, such as inhibitory activity against deleterious wound enzymes and antioxidant activity, and antibacterial activity coupled with biocompatibility to human skin cells.

Download or read book Hydrogels written by Lacramioara Popa and published by BoD – Books on Demand. This book was released on 2019-04-10 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogels, as three-dimensional polymer networks, are able to retain a large amount of water in their swollen state. The biomedical application of hydrogels was initially hampered by the toxicity of cross-linking agents and the limitations of hydrogel formation under physiological conditions. However, emerging knowledge in polymer chemistry and an increased understanding of biological processes have resulted in the design of versatile materials and minimally invasive therapies.The novel but challenging properties of hydrogels are attracting the attention of researchers in the biological, medical, and pharmaceutical fields. In the last few years, new methods have been developed for the preparation of hydrophilic polymers and hydrogels, which may be used in future biomedical and drug delivery applications. Such efforts include the synthesis of self-organized nanostructures based on triblock copolymers with applications in controlled drug delivery. These hydrogels could be used as carriers for drug delivery when combined with the techniques of drug imprinting and subsequent release. Engineered protein hydrogels have many potential advantages. They are excellent biomaterials and biodegradables. Furthermore, they could encapsulate drugs and be used in injectable forms to replace surgery, to repair damaged cartilage, in regenerative medicine, or in tissue engineering. Also, they have potential applications in gene therapy, although this field is relatively new.
