Abstract
The core-shell structured micelles from octenylsuccinated oat β-glucan (OSβG) are able to solubilize β-carotene (βC). This study reveals molecular interactions governing the formation, stabilization, and βC uptake of OSβG micelles (OSβG-Ms) by means such as water contact angle, 1H nuclear magnetic resonance, dynamic light scattering, and confocal laser scanning microscopy. The results indicated that the micellization of OSβG molecules is triggered by hydrophobic interactions between octenylsuccinate (OSA) moieties, while OSβG-Ms are stabilized via both hydrophobic interactions and hydrogen bonds. For their uptake of βC, βC molecules are first adsorbed onto OSβG-Ms by interacting with OSA moieties scattered on micelle surface. By further interacting with OSA moieties located in micelle shell, βC molecules travel across the shell and finally are trapped in the hydrophobic core. In simulated gastrointestinal fluids, βC is controlled released from OSβG-Ms as an integrated consequence of its diffusion as well as the swelling and erosion of OSβG-Ms. As a result, this study first uncovered the mechanism underlying the uptake of βC by OSβG-Ms, which will certainly facilitate the effective loading of hydrophobic ingredients by OSβG-Ms.

Abstract
At present, environmentally friendly and cost-effective disposal of sewage sludge (SS) is the major challenge of wastewater treatment that prompted the concept of sludge valorization. A recent technology, SS conversion into biochar as an efficient catalyst for environmental application, shows great promise to sludge valorization. This review presents the literature and advances of sludge biochar-based catalysts (SBCs), including their synthesis route, physiochemical characteristics, catalytic applications, reaction mechanisms, chemical stability, feasibility, and future aspects. Two major applications of SBCs such as organic pollutants degradation and employing as an electrode material in a microbial fuel cell (MFC) were summarized. The literature has indicated that carbonization of raw or organic/ inorganic-laden sludge produces various metal phase structure and surface functional groups which perform various catalytic reaction such as Fenton-like reaction, ozonation, H2O2/ persulfate activation, and photoreaction in the organic pollutants degradation tests. The degradation efficiency and chemical stability of SBCs have found very satisfying. Moreover, catalysts are highly recyclable, separable, and ensure negligible metal leaching. Secondly, high-temperature carbonized sludge exhibits excellent electrical conductivity which is suitable to use as MFC electrodes. The low-cost sludge biochar-based electrodes (SBEs) performance is comparable to many commercial electrodes. This new technology is concurrently advantageous for environmental pollution remediation, energy production, and harmful metals immobilization, which offer a new route towards SS valorization.

Abstract
In the present study, the properties of two apple sourced-pectin (AP-1 and AP-2) were comparative studied, and their influence on the formation of high internal-phase Pickering emulsions (HIPPEs) was investigated. Results showed that AP-2 has lower polydispersity index (PDI = 2.51) than AP-1. Zein/AP-2 complex nanoparticles (ZAPs-2) was able to stabilize 80% oil-phase to form HIPPEs, while ZAPs-1 failed to remain stable at same oil fraction. After correlating GPC (Gel Permeation Chromatography) results of pectins with their emulsion behavior, pectin PDI was found to play an important role in HIPPEs formation. Storage experiments and rheological properties analysis showed that HIPPEs exerted excellent stability and plasticity. Besides, super-resolution microscopy (including cryo-SEM and STED nanoscopy) depicted an intuitive interface structure of HIPPEs. These findings may contribute some basis to manipulating emulsion performance by adjusting pectin properties, as well as to further understanding the behavior of ZAPs at O/W interface.

Abstract
The use of soft microgel particles for stabilizing emulsions has captured increasing attention across a wide range of disciplines in the past decades. Being soft, the nanoparticles, which are spherical in solution, undergo a structure change when adsorbed at the oil-water interface. This morphology change leads to the special dynamic properties of interface layers and packing structures, which then alter the interfacial tension and rheological properties of the interface. In addition, emulsions stabilized by these particles, known as Pickering emulsions, can be triggered by changing a variety of environmental conditions, which is especially desirable in industrial applications such as oil transportation processes and biphasic catalysis, where the emulsions can be stabilized and destabilized on demand. Although many studies of the behavior of soft microgel nanoparticles at interfaces have been reported, there are still many challenges in gaining a full understanding of the structure, dynamics, and effective interactions between microgels at the interface. In this Feature Article, we address some of the most important findings and problems in the field. They include the adsorption kinetics of soft microgel particles, particle conformation at the interface, pH and thermal responsiveness, and the interfacial rheological properties of soft-particle-occupied interfaces. We also discuss some potential benefits of using emulsions stabilized by soft particles for food applications as an alternative to conventional surfactant-based systems. We hope to encourage further investigation of these problems, which would be very beneficial to extending this knowledge to all other related soft matter systems.

Abstract
The aim of this study is to explore the influence of Ganoderma lucidum-derived polysaccharides (GLP) to coix oil-based microemulsion on pharmaceutical performance and anti-lung cancer treatment. GLP-integrated coix oil-based microemulsion (MEs(PS-GLP)) exhibited a clear spherical shape, small particle size, and good hydrodynamics similar to the coix oil-based microemulsion, but showed a lower zeta potential and a better stability. Fluorescence resonance energy transfer analysis presented that GLP was integrated with microemulsion as a single system. Notably, the average molecular distance between polysaccharide and microemulsion was approximately 1.7 nm. The half-maximal inhibitory concentration of MEs(PS-GLP) against A549 cells was about 119 μg/mL. In vivo imaging studies showed that introduction of GLP promoted the tumor-specific accumulation of microemulsion in comparison with controls. In vivo, antitumor results showed that MEs(PS-GLP) markedly inhibited the tumor growth of A549-bearing xenograft nude mice and obviously improve the serum immune index. Collectively, this study demonstrates the potential mechanism of spatial relation between polysaccharides and microemulsion and validates the significances of GLP on tumoral accumulation and antitumor efficacy.

Abstract
Cancer continues to pose health problems for people all over the world. Nanoparticles (NPs) have emerged as a promising platform for effective cancer chemotherapy. NPs formed by the assembly of proteins and chitosan (CH) through noncovalent interactions are attracting a great deal of interest. However, the poor water solubility of CH and low stability of this kind of NP limit its practical application. Herein, the formation of reduced bovine serum albumin (rBSA) and glycol chitosan (GC) nanoparticles (rBG-NPs) stabilized by hydrophobic interactions and disulfide bonds was demonstrated for paclitaxel (PTX) delivery. The effects of the rBSA:GC mass ratio and pH on the particle size, polydispersity index (PDI), number of particles, and surface charge were evaluated. The formation mechanism and stability of the NPs were determined by compositional analysis and dynamic light scattering. Hydrophobic and electrostatic interactions were the driving forces for the formation of the rBG-NPs, and the NPs were stable under physiological conditions. PTX was successfully encapsulated into rBG-NPs with a high encapsulation efficiency (∼90%). PTX-loaded rBG-NPs had a particle size of ∼400 nm with a low PDI (0.2) and positive charge. rBG-NPs could be internalized by HeLa cells, possibly via endocytosis. An in vitro cytotoxicity study revealed that PTX-loaded rBG-NPs had anticancer activity that was lower than that of a Taxol-like formulation at 24 h but had similar activity at 48 h, possibly because of the slow release of PTX into the cells. Our study suggests that rBG-NPs could be used as a potential nanocarrier for hydrophobic drugs.

Abstract
Novel TiO2/Fe/Fe3C-biochar composite, as a heterogeneous catalyst, has been synthesized by a single-step route, where sewage sludge (SS) and different ratios of nanoparticles (NPs: Fe and Ti) impregnated with chitosan using coagulation and flocculation techniques for subsequent thermal decomposition at 800 °C. The physiochemical properties of samples have been characterized thoroughly and employed in methylene blue (MB) degradation tests. It was found that NPs ratio and chitosan support have significant influences on the properties and catalytic activity of catalysts. Chitosan inclusion successfully improves the surface area and mesoporosity of composites, while high contents of Fe integration reduce surface area and active site (Fe3C) due to Fe0 agglomeration. Though, Ti incorporation produces Ti3+ that activated photosensitivity. Catalyst with the high mesoporous surface, Ti3+, selective Fe3C, and small Fe0 shows superior MB removal competency through concurrent adsorption, photodegradation, and H2O2 activation. Primarily OH and some O2- radicles participating in the degradation reactions evident from scavenging experiments. The maximum MB removal capacity evaluated as 376.9 mg L-1 in neutral pH. Moreover, the catalyst exhibits excellent material stability, recyclability, easy separability, and low Fe-ion leaching (0.11 mg L-1) after catalysis. This study provided new insight into a low-cost and environmentally friendly route of catalyst synthesis using SS, NPs, and chitosan, which concurrently advantageous to SS disposal and wastewater treatment.

Abstract
INTRODUCTION The emergence of numerous tissue engineering and regenerative medicine techniques cell encapsulation paves a way to heal and restore the function of various injured tissues mainly cardiovascular system. Here, we aimed to investigate the role of alginate-gelatin encapsulation on the dynamic of rat cardiomyoblasts in vitro. MATERIALS AND METHODS Rat cardiomyoblasts cell line H9C2 were enclosed by using alginate-gelatin microspheres and incubated for 7 days. MTT method was used to examine cell viability. The level of genes associated with cardiomyoblasts maturation MYL7, NPPA, NKX2-5, and GATA4 real-time PCR. ELISA was used to measure the protein levels of Bcl-2 and Bax factor post-encapsulation. The level of SOD, GPx, and TAC was detected by biochemical analyses. Western blotting was performed to measure the content of AMP-activated protein kinase. RESULTS We found that encapsulation was able to increase the viability of rat cardiomyocytes after 7 days. The decreased level of Bcl-2 (p < 0.001) coincided with non-significant differences in the level of Bax (p > 0.05). The transcription level of all genes MYL7, NPPA, NKX2-5, and GATA4 were found to down-regulate compared to the control non-treated cells (p < 0.05). No significant differences were found regarding the level of SOD, GPx, and TAC compared to the control (p>0.05). According to western blotting, revealed a reduced level of AMPK following 7-day incubation of rat cardiomyoblasts (p < 0.05). CONCLUSION Data confirmed that the encapsulation of rat cardiomyoblasts with alginate-gelatin microspheres maintained the cells multipotentiality.

Abstract
In this study, we present hybrid microgels made of starch nanoparticles (SNPs) and poly( N-isopropylacrylamide) [p(NIPAM)]. SNPs were formed through nanoprecipitation. Hybrid microgels were prepared by surfactant-free precipitation polymerization (SFPP) or in the presence of surfactant precipitation polymerization (PP) at different NIPAM/SNP ratios. Dynamic light scattering results of hybrid microgels synthesized by SFPP revealed changes in volume phase transition temperature according to SNP amount, where the increase in the hydrophilic content caused small shifts in the lower critical solution temperature (LCST), reaching nearly 35 °C. Colloidal stability was improved with the SNP content, leading to increased stability because of the hydroxyl groups. Small-angle X-ray scattering indicates a core-shell structure above the LCST, where SNPs chains cover a p(NIPAM) core. Swelling curves experimentally obtained were analyzed using the Flory-Rehner model, where the interaction parameter (χ) has been modeled either by a series expansion of the swelling ratio or by a Hill-like equation for a cooperative thermotropic transition.

Abstract
The account presents survey of our systematic studies on chitosan. Only this polysaccharide bears cationic charges, possesses antimicrobial activity and wound healing ability that make it highly appropriate for using in medicine, biomedical engineering, cosmetics, food, packaging. However, its application meets with severe limitation. Chitosan belongs to polysaccharides that do not jellify solutions. Main approaches are based on the chemical modifications and cross-linking, but these treatments impairs therewith the biocompatibility and biological activity of chitosan. We have developed approaches in which monolithic hydrogels are fabricated via the mineralization of polysaccharide by method of green sol-gel chemistry and via the formation of polyelectrolyte complex with oppositely charged counterparts in the regime of its charging by means of regulated acidification. The latter approach was also extended for the preparation of chitosan bionanocomposites and films with nanoparticles.

Abstract
Nowadays, edible coatings incorporated with nanostructures as systems of controlled release of flavors, colorants and/or antioxidants and antimicrobial substances, also used for thermal and environmental protection of active compounds, represent a gap of opportunity to increase the shelf life of food highly perishable, as well as for the development of new products. These functionalized nanostructures have the benefit of incorporating natural substances obtained from the food industry that are rich in polyphenols, dietary fibers, and antimicrobial substances. In addition, the polymers employed on its preparation, such as polysaccharides, solid lipids and proteins that are low cost and developed through sustainable processes, are friendly to the environment. The objective of this review is to present the materials commonly used in the preparation of nanostructures, the main ingredients with which they can be functionalized and used in the preparation of edible coatings, as well as the advances that these structures have represented when used as controlled release systems, increasing the shelf life and promoting the development of new products that meet the characteristics of functionality for fresh foods ready to eat.

Abstract
Currently, the major issues in the treatment of osteoarticular tuberculosis (TB) after implant placement are low drug concentration at the infected focus and drug resistance resulting from the long-term chemotherapy. The application of drug-loaded polymeric multilayers on implantable devices offers a promising solution to the problems. Herein, a poly(ethylene glycol)-based hydrogel film embedded with isoniazid (INH)-loaded alginate microparticles was fixed to Ti implants via adhesive polydopamine, subsequently capped by poly(lactic-co-glycolic acid) membranes for the sustained and localized delivery of the anti-TB drug. The antibacterial efficacy of the released INH was confirmed by a 4.5 ± 0.8 cm inhibition zone formed in the fourth week after inoculation of Mycobacterium tuberculosis. The INH-loaded Ti implants showed no toxicity to the osteoblast cell and provided a consistent drug release for nearly one week in vitro. The release profile in vivo showed a high local concentration and low systemic exposure. The local INH concentration could be kept higher than its minimum inhibitory concentration over a period of 8 weeks, which proves that it is a promising strategy to improve the severe osteoarticular TB treatment.

Abstract
The advent of nanomedicine has rejuvenated the need for increased understanding of the fundamental physicochemical properties of polymeric amphiphiles. Hyaluronic acid (HA) is a hydrophilic polysaccharide that is frequently conjugated to hydrophobic moieties and then used to entrap dyes and therapeutics. Here, we develop computational models to examine the effects of the hydrophobic modification on supramolecular behavior among three systematically designed HA derivatives substituted with alkyl chains of increasing length. Our simulations coalesce with experimentally obtained results to demonstrate the dependence of supramolecular behavior on intramolecular forces. We show that the formation of clearly defined hydrophobic domains in samples of octadecylamine-modified HA compared to HA conjugates with shorter alkyl chains is a result of more favorable hydrophobic interactions. Trends in hydrodynamic radius and polydispersity are observed in experimental results that coalesce with theoretical calculations, suggesting that supramolecular properties are dependent on the physicochemical characteristics of individual polymer strands.

Abstract
Polysaccharides are natural biopolymers that have been recognized to be the most promising hosts for the synthesis of metallic nanoparticles (MNPs) because of their outstanding biocompatible and biodegradable properties. Polysaccharides are diverse in size and molecular chains, making them suitable for the reduction and stabilization of MNPs. Considerable research has been directed toward investigating polysaccharide-based metallic nanoparticles (PMNPs) through host⁻guest strategy. In this review, approaches of preparation, including top-down and bottom-up approaches, are presented and compared. Different characterization techniques such as scanning electron microscopy, transmission electron microscopy, dynamic light scattering, UV-visible spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction and small-angle X-ray scattering are discussed in detail. Besides, the applications of PMNPs in the field of wound healing, targeted delivery, biosensing, catalysis and agents with antimicrobial, antiviral and anticancer capabilities are specifically highlighted. The controversial toxicological effects of PMNPs are also discussed. This review can provide significant insights into the utilization of polysaccharides as the hosts to synthesize MPNs and facilitate their further development in synthesis approaches, characterization techniques as well as potential applications.

Abstract
Despite recent advances in diagnostic and therapeutic methods in antifungal research, aspergillosis still remains a leading cause of morbidity and mortality. One strategy to address this problem is to enhance the activity spectrum of known antifungals, and we now report the first successful application of Candida antarctica lipase (CAL) for the preparation of optically enriched fluconazole analogues. Anti-Aspergillus activity was observed for an optically enriched derivative, (-)-S-2-(2',4'-difluorophenyl)-1-hexyl-amino-3-(1‴,2‴,4‴)triazol-1‴-yl-propan-2-ol, which exhibits MIC values of 15.6 μg/ml and 7.8 μg/disc in broth microdilution and disc diffusion assays, respectively. This compound is tolerated by mammalian erythrocytes and cell lines (A549 and U87) at concentrations of up to 1,000 μg/ml. When incorporated into dextran nanoparticles, the novel, optically enriched fluconazole analogue exhibited improved antifungal activity against Aspergillus fumigatus (MIC, 1.63 μg/ml). These results not only demonstrate the ability of biocatalytic approaches to yield novel, optically enriched fluconazole derivatives but also suggest that enantiomerically pure fluconazole derivatives, and their nanotized counterparts, exhibiting anti-Aspergillus activity may have reduced toxicity.

Abstract
This mini-review is focused on an engineering approach to produce polysaccharides-based microparticles for nutraceutical and pharmaceutical purposes. A brief introduction about the fundamental properties of polysaccharides and their use as microsystems in food, cosmetics, and pharmaceutics, and a summary of the most important methods of preparation are described. Then, a novel method based on the ultrasonic atomization of solutions of the two most used polysaccharides, alginate and chitosan, followed by ionotropic gelation to produce enteric microsystems for oral administration and, in particular, the basic mechanisms of the encapsulation of molecules with different size and hydrophilicity, are investigated. This mini-review will show therefore the pathway to correctly design a polysaccharide microcarrier for the encapsulation of active molecules with different properties: from the choice of materials features, to the selection and the optimization of production methods with the aim to reduce costs and energy (ionotropic gelation coupled to ultrasonic atomization), to the control of the final carrier size (by purposely developed predictive models), at last to the optimization of encapsulation properties (predicting by model the drug leakage and providing different solutions to avoid it).

Abstract
This investigation describes the preparation of magnetically doped degradable microcrystalline cellulose (MCC) nanocomposite particles with application potential in biotechnology, solid support for biomolecule/water purification, oil recovery from water and beyond. MCC was first extracted from cotton wool, the most abundant biocompatible polymer, by sulfuric acid hydrolysis and the effect of acid strength was examined. The size of the elongated fiber structure was reduced with increasing acid strength. MCC particles extracted by treatment with 70% sulfuric acid were used to prepare magnetic MCC nanocomposite particles. The nanocomposite particles named as MCC/Fe3O4 were prepared via in situ co-precipitation of Fe+3/Fe+2 from their alkaline solution. The precipitated Fe3O4 nanoparticles are expected to be bonded with MCC particles via hydrogen bonding. The nanocomposite dispersion was colloidally stable and the particles responded when external magnetic field was applied. It was possible to control the magnetic property by regulating the content of iron oxide.

Abstract
The polysaccharides of Dicliptera chinensis (L.) Juss. (DCP-1 and DCP-2) were extracted and isolated using the methods of water extract-ethanol precipitate and sephadex column chromatography and characterized by gel permeation chromatography (GPC), Fourier transform infrared spectrometry (FT-IR) and gas chromatography (GC), respectively. The antioxidant activity of DCPs was evaluated by scavenging activity of DPPH, hydroxyl, superoxide anion and ABTS radical. Moreover, the anti-aging activity of DCP-2 was investigated using an aging model-induced by D-galactose (D-gal) in mice. The results show that the weight average molecular weight (Mw) of DCP-2 was 2 273Da with a narrow polydispersity index of 1.01, and it was a heteropolysaccharide and consisted of glucose, galactose, arabinose, rhamnose and mannose with a molar ratio of 3.20:2.54:1.69:1.58:1.00. DCP-2 had stronger antioxidant activity against DPPH, hydroxyl, superoxide anion and ABTS radical, while DCP-1 had hardly any antioxidant activity and DCP had weaker antioxidant activity. Furthermore, DCP-2 can enhance antioxidant capacity and had anti-aging activity against D-gal induced aging mice. These results proposed that DCP-2 might be developed as a potential functional food with the activity of anti-aging.

Abstract
Nanoparticles have been extensively explored as effective means to deliver chemotherapeutic agents or photosensitizers for chemotherapy or photodynamic therapy (PDT) against cancer. In the present work, pheophorbide A (PheoA), a hydrophobic photosensitizer, was conjugated via a redox-sensitive disulfide linkage to alginate (PheoA-ALG). Anticancer agent, doxorubicin (DOX), was also loaded within the PheoA-ALG nanoparticles (DOX/PheoA-ALG NPs) and used as drug carriers for combinational antitumor treatment. The DOX/PheoA-ALG NPs were spherical in shape with a uniform diameter of approximately 210 nm. Redox-responsive drug releasing properties were shown by the DOX/PheoA-ALG NPs, with an accelerated amount of DOX and PheoA release observed in the presence of a high glutathione level (10 mM). Cellular uptake results showed that DOX/PheoA-ALG NPs were readily taken up by B16 tumor cells (murine melanoma) and enhanced DOX and PheoA uptake were detectable in the DOX/PheoA-ALG NPs-treated B16 cells in comparison to carrier free drugs. DOX/PheoA-ALG NPs also elicited intracellular ROS generation, which leads to enhanced toxicity in B16 cells. In vivo studies using B16 tumor-bearing mice further demonstrated that DOX/PheoA-ALG NPs were preferentially accumulated in tumor tissues, resulting in substantial inhibition of B16 tumor growth by chemotherapy and photodynamic therapy, which is also attributable to DOX/PheoA-ALG NP-elicited increase of serum INF-λ levels. Our results demonstrate a major potential of DOX/PheoA-ALG NPs for combinational cancer therapy.

Abstract
The aim of this research was to develop novel W1/O/W2 nanoemulsions for encapsulating Hohenbuehelia serotina polysaccharides to resolve the low soluble and unstable problems. The prepared parameters (PVA content, polysaccharides concentration, stirring speed and stirring time) of H. serotina polysaccharides nanoemulsions were optimized based on the response surface methodology. Through systematic analysis of the model, the optimal conditions were chosen as PVA content of 0.60%, polysaccharides concentration of 9.7μg/mL, stirring speed of 11,000rpm, and stirring time of 2.4min. Under the optimal prepared conditions, the encapsulation efficiency and particle size were respectively 75.42±0.69% and 410.1±2.3nm, which were well consistent with the predicted values. The optimized nanoemulsions possessed the spherical multilayer structure with the zeta potential value of -52.34±5.62mV, and they could be stably stored at 25°C for 6days. Moreover, the nanoemulsions had the excellent sustained-release characteristics in the simulated gastric fluid. This study may provide a valuable contribution for the application of nanoemulsions in the functional food field.

Abstract
Nanotechnology is an emerging and rapidly developing toolbox that has novel and unique applications to food science and agriculture. Fast and impressive developments in nanotechnology for food and agriculture have led to new experimental prototype technologies and products. Developing various types of nanodelivery systems, detection tools, nanoscale modifications of bulk or surface properties, fabrication of wide-range bionanosensors, and biodegradable nanoplatforms can potentially improve consumer health and safety, product shelf life and stability, bioavailability, environmental sustainability, efficiency of processing and packaging, and real-time monitoring. Some recently developed nanotechnology techniques and potential product applications of nanotechnology are summarized in this review. Exposure to nanomaterials may be harmful to the consumer and the environment and might increase the potential of risk. For this reason, evaluation of the potential risks resulting from the interaction of nanomaterials with biological systems, humans, and the environment is also reviewed.

Abstract
The development of delivery systems using natural polymers such as gums offers distinct advantages, such as, biocompatibility, biodegradability, and cost effectiveness. Cashew gum (CG) has rheological and mucoadhesive properties that can find many applications, among which the design of delivery systems for drugs and other actives such as larvicide compounds. In this review CG is characterized from its source through to the process of purification and chemical modification highlighting its physicochemical properties and discussing its potential either for micro and nanoparticulate delivery systems. Chemical modifications of CG increase its reactivity towards the design of delivery systems, which provide a sustained release effect for larvicide compounds. The purification and, the consequent characterization of CG either original or modified are of utmost importance and is still a continuing challenge when selecting the suitable CG derivative for the delivery of larvicide compounds.
