Abstract
A simple method to fabricate redox-responsive composite hydrogel films via incorporating chitosan (CS) microspheres into carboxymethyl cellulose (CMC) hydrogel using a di-sulphide cross-linker cystamine dihydrochloride (CYS) have done in this paper. Dual drugs, an anticancer, 5-Fluorouracil (5-FU) and an antibiotic, Tetracycline Hydrochloride (TH) were used as model drugs. The prepared composite hydrogel films were characterized using FTIR, SEM, rheology measurement, mechanical and swelling tests. Our results showed that the well dispersed spherical CS microspheres endowed hydrogel film increased mechanical properties and swellability. In vitro drug release displayed an accelerated release under weak acidic or reducing media. The in vitro cytotoxicity and cell apoptosis studies showed the drug-loaded composite film caused enhanced inhibition to HepG2 cells in presence of glutathione (GSH). Moreover, the film has exhibited excellent antimicrobial efficacy against E.coli and Staphylococcus aureus. Therefore, our simple and effective dual drug-loaded system has the potential to be used for cancer therapy in the future.

Abstract
A magnetic-pH dual responsive drug delivery system was prepared for antibacterial therapy to reduce the side effects on nonpathological cells or tissues. Iron oxide (Fe3O4) core was surface-functionalized with silane coupling agents to link β‑cyclodextrin (β-CD) (CDMNP), and a polypseudorotaxanes shell where polyethyleneglycol chains threaded much CD molecules was further prepared on the magnetic Fe3O4 core (CDMNP-PEG-CD) to enhance loading capacity of roxithromycin (ROX). CDMNP-PEG-CD with a hydrodynamic diameter of ~168 nm was cytocompatible, superparamagnetic, magnetic-responsive and stable for 180 min of storage. No significant interaction with serum albumin was shown for the nanocomposites. The in vitro release from ROX-loaded CDMNP-PEG-CD nanocomposites was about 76% of total drug within 30 min at pH 1.0, 1.6-fold of that at pH 7.4 and 2-fold of that at pH 8.0, presenting pH-responsive drug release behaviors. The nanocomposites showed positive antibacterial activity against both E. coli and S. aureus based on an agar diffusion method. The antibacterial activity of the nanocomposites was more sensitive against E. coli than S. aureus, and the inhibition halo against E. coli was 85% more than that of Fe3O4. CDMNP-PEG-CD nanocomposites allowed for the localization and fast concentration of hydrophobic drugs, providing a broad potential range of therapeutic applications.

Abstract
In recent decades, cellulose has been extensively investigated due to its favourable properties, such as hydrophilicity, low-cost, biodegradability, biocompatibility, and non-toxicity, which makes it a good feedstock for the synthesis of biocompatible hydrogels. The plentiful hydrophilic functional groups (such as hydroxyl, carboxyl, and aldehyde groups) in the backbone of cellulose and its derivatives can be used to prepare hydrogels easily with fascinating structures and properties, leading to burgeoning research interest in biomedical applications. This review focuses on state-of-the-art progress in cellulose-based hydrogels, which covers from their preparation methods (including chemical methods and physical methods) and physicochemical properties (such as stimuli-responsive properties, mechanical properties, and self-healing properties) to their biomedical applications, including drug delivery, tissue engineering, wound dressing, bioimaging, wearable sensors and so on. Moreover, the current challenges and future prospects for cellulose-based hydrogels in regard to their biomedical applications are also discussed at the end.

Abstract
Burn wounds are associated with a series of risks, such as infection and pathologic scar tissue formation, which significantly delay wound healing and lead to complications. In this study, we successfully fabricated a dextran-hyaluronic acid (Dex-HA) hydrogel enriched with sanguinarine (SA) incorporated into gelatin microspheres (GMs), which had high porosity, good swelling ratio, enhanced NIH-3T3 fibroblast cell proliferation, and sustained SA release profile. The in vitro degradation results indicate that the SA/GMs/Dex-HA hydrogel can be degraded. The in vitro antibacterial tests showed that the SA/GMs/Dex-HA hydrogel can inhibit methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli). We evaluated the wound-healing effects and antibacterial properties of SA/GMs/Dex-HA hydrogels in a rat full-thickness burn infection model. The hematoxylin-eosin (H&E) and Masson's trichrome staining results of the SA/GMs/Dex-HA hydrogel showed that it improved re-epithelialization and enhanced extracellular matrix remodeling, and immunohistochemistry results showed that the expression of TGF-β1 and TNF-α was decreased, while the TGF-β3 expression was increased. Our findings suggest that the SA/GMs/Dex-HA hydrogel provides a potential way for infected burn treatment with high-quality and efficient scar inhibition.

Abstract
With ever increasing scientific knowledge and awareness, research is underway around the globe to design new types of stimuli (external/internal) responsive nano-carriers for biotechnological applications at large and biomedical/pharmaceutical in particular. Based on literature evidence, stimuli-responsive carriers have been classified into four major categories, i.e. (1) physical, (2) chemical, (3) biological, and (4) dual (combination of any of the first three classes). Among various types, redox-responsive nano-carriers are of supreme interests and discussed here in this review. The difference in redox potential in tumor and normal tissue is considered as a potential target for tumor targeting leading to the development of redox-responsive drug delivery systems (DDS). In this regard, a high concentration of glutathione in tumor/intracellular environment has extensively been exploited. Disulfide bonds were found as a promising tool for designing redox-responsive which tend to cleave in a reductive environment forming sulfhydryl groups. Many nano-carriers have been explored widely to control tumor growth. These systems were used against the tumor xenograft animal model and showed improved tumor targeting with tumor growth inhibition. Herein, an effort has been made to summarize various aspects from design to development of numerous types of redox-responsive DDS including liposomes, micelles, nanoparticles, nanogel and prodrug based nanomedicines. An emphasis is also given on various types of nano-carriers with special reference to the tumor-targeted drug delivery applications. Also, dual responsive nano-carriers (in addition to redox-responsive) have also been briefly discussed. Towards the end of the chapter, the information is also given on their future perspectives.
