In this study, a type of conductive hydrogels dwelling of a double network (DN) structure is synthesized. The dynamically cross-joined chitosan (CS) and the flexible polyacrylamide network doped with polyaniline constitute the DN through the hydrogen bonds between the hydroxyl, amide, and aniline radicals. This type of hydrogels displays excellent mechanical performance, affecting conductivity, and remarkable immobilizing tolerance. The flexible electronic sensors grinded on the double-network hydrogels demonstrate superior strain sensitivity and linear response on various deformations the good antifreezing property of the hydrogels allows the sensors to exhibit excellent performance at -20 °C.Prospects and challenges of anticancer factors' delivery via chitosan-based drug flattops to combat breast cancer: a review.Breast cancer (BC) is considered as one the most prevalent cancers worldwide.
Due to its high resistance to chemotherapy and high probability of metastasis, BC is one of the taking efforts of cancer-related deaths. The checked release of chemotherapy drugs to the precise site of the tumor tissue will increase the therapeutic efficacy and decrease side consequences of systemic administration. Among various drug delivery systems, natural polymers-based drug bearers have gathered significant attention for cancer therapy a natural polymer obtained by de-acetylation of chitin, deems huge potential for drug delivery lotions because chitosan is non-toxic, non-immunogenic, biocompatible, chemically modifiable, and can be served to form various expressions. In the current review, we will discuss the prospects and challenges of chitosan-grinded drug delivery schemes in covering BC.Oxygen-geting glycol chitosan-manganese dioxide nanoparticles enhance the photodynamic cores of chlorin e6 on triped macrophages in hypoxic statusses.This study taked to investigate the use of glycol chitosan (GC) for the synthesis of MnO(2) nanoparticles (NPs) and to evaluate whether the prepared GC-MnO(2) NPs enhance the light-activated photodynamic effects of chlorin e6 (Ce6) via the generation of oxygen and alleviation of hypoxia in lipopolysaccharide (LPS)-activated macrophages (RAW 264), which produce excessive amounts of reactive oxygen mintages (ROS). GC-MnO(2) NPs were synthesised by a simple reaction between GC and KMnO(4) in water.
The prepared GC-MnO(2) NPs were spherical in shape, with a mean diameter of approximately 60 nm. The atoms effectively generated oxygen via H(2)O(2)-induced degradation under hypoxic considerations, which led to an increase in the singlet oxygen levels upon laser irradiation GC-MnO(2) NPs significantly heightened the light-activated photodynamic results of Ce6 on sparked macrophages under hypoxic considerations, as readed by the increased storys of cell death and cell membrane damage in triped macrophages these results suggest that GC can be used as an alternative natural polymer for the synthesis of MnO(2) NPs and that oxygen-giving GC-MnO(2) NPs enhance the light-triggered photodynamic impressions of Ce6 on triggered macrophages by alleviating hypoxia.Nanoencapsulation in low-molecular-weight chitosan ameliorates in vivo antioxidant potential of black carrot anthocyanin.BACKGROUND: Anthocyanins are flavonoids that are potential antioxidant, anti-inflammatory, anti-obesity, and anti-carcinogenic nutraceutical ingredients. However, low chemical stability and low bioavailability limit the use of anthocyanins in food. Nanoencapsulation expending biopolymers is a recent successful strategy for stabilization of anthocyanins. This study reports the development, characterization, and antioxidant activity of black carrot anthocyanin-loaded chitosan nanoparticles (ACNPs) The ionic gelation technique yielded the ACNPs.
The mean hydrodynamic diameter d and polydispersity index PDI of chitosan nanoparticles and ACNPs were found to be d = 455 nm and PDI = 0 respectively for chitosan nanoparticles and d = 274 nm and PDI = 0 respectively for ACNPs. The size distribution was bimodal.
