Abstract
One of the critical steps in gene therapy is the successful delivery of the genes. Immunogenicity and toxicity are major issues for viral gene delivery systems. Thus, non-viral vectors are explored. A cationic polysaccharide like chitosan could be used as a nonviral gene delivery vector owing to its significant interaction with negatively charged nucleic acid and biomembrane, providing effective cellular uptake. However, the native chitosan has issues of targetability, unpacking ability, and solubility along with poor buffer capability, hence requiring modifications for effective use in gene delivery. Modified chitosan has shown that the "proton sponge effect" involved in buffering the endosomal pH results in osmotic swelling owing to the accumulation of a greater amount of proton and chloride along with water. The major challenges include limited exploration of chitosan as a gene carrier, the availability of high-purity chitosan for toxicity reduction, and its immunogenicity. The genetic drugs are in their infancy phase and require further exploration for effective delivery of nucleic acid molecules as FDA-approved marketed formulations soon.

Abstract
Convenient chemical modification of biomacromolecules to create novel biocompatible functional materials satisfies the current requirements of sustainable chemistry. Dendronization of chitosan with dendritic oligoethylene glycols (OEGs) paves a strategy for the preparation of functional dendronized chitosans (DCSs) with unprecedent thermoresponsive behavior, which inherit biological features from polysaccharides and the topological features from dendritic OEGs. In addition, densely packed dendritic OEG chains around the backbone provide efficient cooperative interactions and form an intriguing confined microenvironment based on the degradable biopolymers. In this perspective, we describe the principle for the preparation of the thermoresponsive DCSs, and focus on the molecular envelop effect from the hydrophobic microconfinement to the encapsulated guest molecules or moieties. Particular attention is put on their capacity to regulate behavior and the functions of the encapsulated guests through thermally-mediated dehydration and collapse of the densely packed dendritic OEGs. We believe that the methodology described here may provide prospects for the fabrication of functional materials from biomacromolecules, especially when used as environmentally friendly nanomaterials or in accurate diagnosis and therapy.

Abstract
Nose-to-brain delivery presents a promising alternative route compared to classical blood-brain barrier passage, especially for the delivery of high molecular weight drugs. In general, macromolecules are rapidly degraded in physiological environment. Therefore, nanoparticulate systems can be used to protect biomolecules from premature degradation. Furthermore, targeting ligands on the surface of nanoparticles are able to improve bioavailability by enhancing cellular uptake due to specific binding and longer residence time. In this work, transferrin-decorated chitosan nanoparticles are used to evaluate the passage of a model protein through the nasal epithelial barrier in vitro. It was demonstrated that strain-promoted azide-alkyne cycloaddition reaction can be utilized to attach a functional group to both transferrin and chitosan enabling a rapid covalent surface-conjugation under mild reaction conditions after chitosan nanoparticle preparation. The intactness of transferrin and its binding efficiency were confirmed via SDS-PAGE and SPR measurements. Resulting transferrin-decorated nanoparticles exhibited a size of about 110-150 nm with a positive surface potential. Nanoparticles with the highest amount of surface bound targeting ligand also displayed the highest cellular uptake into a human nasal epithelial cell line (RPMI 2650). In an air-liquid interface co-culture model with glioblastoma cells (U87), transferrin-decorated nanoparticles showed a faster passage through the epithelial cell layer as well as increased cellular uptake into glioblastoma cells. These findings demonstrate the beneficial characteristics of a specific targeting ligand. With this chemical and technological formulation concept, a variety of targeting ligands can be attached to the surface after nanoparticle formation while maintaining cargo integrity.

Abstract
It is meaningful and challenging to design and develop a fluorescent probe for living cell temperature sensors since it should have good cell compatibility and high-resolution features. In this work, the temperature-sensitive polymer of PA-loaded cysteine (Cys) modified chitosan (Cs) grafted PNIPAM (Cs-Cys-PN/PA) with aggregation-induced emission enhancement (AIEE) properties that reversible hydrogel in an aqueous solution is synthesized. Here, we interpret the temperature stimulus as a monochromatic signal through the AIEE active reversible hydrogel of Cs-Cys-PN. In addition, the cytotoxicity test shown that Cs-Cys-PN has good biocompatibility. Cs-Cys-PN can be used to build antibacterial drugs carrier, thereby providing a new platform of self-released drugs for the treatment of bacterial infections.

Abstract
In the present study, we fabricated non-toxic, injectable, and thermo-sensitive NIPAAm-g-chitosan (NC) hydrogels with thiol modification for introduction of disulfide cross-linking strategy. Previously, NIPAAm and chitosan copolymer has been proven to have excellent biocompatibility, biodegradability and rapid phase transition after injection, suitable to serve as cell carriers or implanted scaffolds. However, weak mechanical properties significantly limit their potential for biomedical fields. In order to overcome this issue, we incorporated thiol side chains into chitosan by covalently conjugating N-acetyl-cysteine (NAC) with carbodiimide chemistry to strengthen mechanical properties. After oxidation of thiols into disulfide bonds, modified NC hydrogels did improve the compressive modulus over 9 folds (11.4 kPa). Oscillatory frequency sweep showed a positive correlation between storage modulus and cross-liking density as well. Additionally, there was no cytotoxicity observed to mesenchymal stem cells, fibroblasts and osteoblasts. We suggested that the thiol-modified thermo-sensitive polysaccharide hydrogels are promising to be a cell-laden biomaterial for tissue regeneration.

Abstract
Successful intracellular delivery of genes requires an efficient carrier, as genes by themselves cannot diffuse across cell membranes. Because of the toxicity and immunogenicity of viral vectors, nonviral vectors are gaining tremendous interest in research. In this work, we have investigated the temperature-dependent DNA condensation efficiency of various compositions of a thermosensitive block copolymer viz., poly(N-isopropylacrylamide)-b-poly(2-(diethylamino)ethyl methacrylate) (PNIPA-b-PDMAEMA). Three different copolymer compositions of varying molecular weights were successfully synthesized via the RAFT polymerization technique. Steady-state fluorescence and circular dichroism (CD) spectroscopies, dynamic light scattering (DLS) and zeta potential measurements, agarose gel electrophoresis, and atomic force microscopy techniques were utilized to study the interaction of the copolymers with DNA at temperatures above and below the critical aggregation temperature (CAT). All these experiments revealed that, above the CAT, there was formation of highly stable and tight polymer-DNA complexes (polyplexes). The size of polyplexes was dependent on the temperature up to a certain charge ratio, as determined by the DLS results. The results obtained from temperature-dependent fluorescence spectroscopy, CD, and gel electrophoresis indicated that the DNA molecules were shielded more from aqueous exposure above the CAT because of the formation of relatively more compact complexes. The polyplexes also exhibited changes in the particle morphology below and above the CAT, with particles generated above CAT being more spherical in morphology. These results suggested at the possibility of modulating the complex formation by temperature modification. The present biophysical studies would provide new physical insight into the design of novel gene carriers.

Abstract
Nanoparticles (NPs) are novel drug delivery systems that have been attracting more and more attention in recent years, and have been used for the treatment of cancer, infection, inflammation and other diseases. Among the numerous classes of materials employed for constructing NPs, organic polymers are outstanding due to the flexibility of design and synthesis and the ease of modification and functionalization. In particular, NP based amphiphilic polymers make a great contribution to the delivery of poorly-water soluble drugs. For example, natural, biocompatible and biodegradable products like polysaccharides are widely used as building blocks for the preparation of such drug delivery vehicles. This review will detail carbohydrate based amphiphilic polymeric systems for cancer therapy. Specifically, it focuses on the nature of the polymer employed for the preparation of targeted nanocarriers, the synthetic methods, as well as strategies for the application and evaluation of biological activity. Applications of the amphiphilic polymer systems include drug delivery, gene delivery, photosensitizer delivery, diagnostic imaging and specific ligand-assisted cellular uptake. As a result, a thorough understanding of the relationship between chemical structure and biological properties facilitate the optimal design and rational clinical application of the resulting carbohydrate based nano delivery systems for cancer therapy.

Abstract
Three small organic molecules containing different numbers of cyclen and imidazolium units were synthesized. Their interactions with plasmid DNA and their potential for gene delivery vectors were investigated. Agarose gel retardation and ethidium bromide exclusion assays revealed that these molecules can effectively condense DNA, and compounds with higher molecular weights are needed to lower w/w ratio for full condensation. Dynamic light scattering (DLS) and transmission electron microscopy (TEM) indicated that these compounds may form nanosized spherical particles with DNA. Furthermore, the complex formed from 10, i.e., 10/DNA, can partially release DNA from compact state at a relatively higher concentration of NaCl (200 mM). In the presence of the lipid 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), 10 could transfer plasmid DNA into BEL-7402 cells. In addition, these compounds exhibited much lower cytotoxicity than PEI 25 kDa.

Different from synthetic materials, natural polymers are abundant in nature, renewable, non-toxic, biocompatible and biodegradable. Owing to the presence of positive charges, natural cationic polymers have found important applications in many biological fields, such as drug/gene delivery and tissue engineering. In gene delivery, natural cationic polymers can condense nucleic acids, protect them from degradation, lower the immunogenicity and improve overall transfection efficiency. In drug delivery, cationic functional groups can alter the amphiphilic properties of the polymers to ensure their suitable applications for delivering hydrophobic or protein drugs. After simple chemical modification, the derivatives of natural cationic polymers show improved performance as functional delivery carriers. In this chapter, details on the chemical modification of natural cationic polymers and their applications in gene/drug delivery is discussed.

Abstract
Nanomaterials based on chitosan have emerged as promising carriers of therapeutic agents for drug delivery due to good biocompatibility, biodegradability, and low toxicity. Chitosan originated nanocarriers have been prepared by mini-emulsion, chemical or ionic gelation, coacervation/precipitation, and spray-drying methods. As alternatives to these traditional fabrication methods, self-assembled chitosan nanomaterials show significant advantages and have received growing scientific attention in recent years. Self-assembly is a spontaneous process by which organized structures with particular functions and properties could be obtained without additional complicated processing or modification steps. In this review, we focus on recent progress in the design, fabrication and physicochemical aspects of chitosan-based self-assembled nanomaterials. Their applications in drug delivery of different therapeutic agents are also discussed in details.

Abstract
The major goal of this study is to design, synthesize, and evaluate linoleic acid and penetratin dual-functionalized chitosan (CS-Lin-Pen) as a nonviral gene carrier. The amphiphilic CS-Lin-Pen self-assembles to form cationic micelles in an aqueous environment. These polymeric micelles exhibited excellent hemocompatibility and cell viability, as evaluated by in vitro hemolysis and MTT assay, respectively. When CS-Lin-Pen micelles were added to plasmid DNA (pDNA) solution, the electrostatic interaction between the cationic micelles and anionic pDNA led to the formation of stable CS-Lin-Pen/pDNA polyplexes with ~100 nm in size. The resultant polyplexes demonstrated ~5-fold higher cellular uptake as compared to unmodified chitosan. Furthermore, CS-Lin-Pen micelles showed efficient protection of pDNA from DNase I attack and exhibited ~34-40-fold higher transfection in comparison with unmodified chitosan in HEK 293, CHO, and HeLa cells. These findings illustrate that the CS-Lin-Pen micelles could be exploited as a potential nonviral vector for efficient gene therapy.

Abstract
The delivery of nucleic acids (NAs) is hindered by several factors, such as the size of the biomolecule (micron size for plasmid DNA), the presence of different biological barriers or the degradation of NAs. Most of these limitations are avoided by complexation with polycationic species, which collapse NAs into nanometer-sized polyplexes that can be efficiently internalized into the target cells. Because there are subtle changes in physiological conditions, such as the drop in pH at the endosome, or the increase in temperature in tumor tissue, stimuli responsive synthetic polymers are ideal candidates for the synthesis of efficient gene delivery vehicles. In this chapter, representative examples of “smart” polypexes that exploit these changes in physiological environment for the delivery of NAs are described, and the transfection efficiency of pH-, redox-, temperature- and light-responsive polyplexes is analyzed.

Abstract
Thermal targeting of therapeutic genes can enhance local gene concentration to maximize their efficacy. However, lack of safe and efficient carriers has impeded the development of this delivery option. Herein, we report the preparation and evaluation of a hybrid recombinant material, p[Asp(DET)](53)ELP(1-90), that possess a thermo-responsive elastin-like polypeptide (ELP) segment and a diethylenetriamine (DET) modified poly-L-aspartic acid segment. The term, hybrid, indicates that the material was prepared by genetic engineering and synthetic chemistry. In summary, the thermal phase transition behavior and cytotoxicity of the biodegradable copolymer were studied. The polyplexes formed by the copolymer and pGL4 plasmid were characterized by dynamic light scattering and ζ-potential measurements. The polyplexes retained the thermal phase transition behavior conferred by the copolymer; however, they exhibited a two-step transition process not seen with the copolymer. The polyplexes also showed appreciable transfection efficiency with low cytotoxicity.

Abstract
Among non-viral vectors, chitosan and chitosan derivatives have been developed in vitro and in vivo for DNA and siRNA delivery systems because of their cationic charge, biodegradability and biocompatibility, as well as their mucoadhesive and permeability-enhancing properties. However, the transfection efficiency of chitosan is too low for clinical application. Studies indicated that the transfection efficiency depends on a series of chitosan-based formulation parameters, such as the Mw of chitosan, its degree of deacetylation, the charge ratio of chitosan to DNA/siRNA (N/P ratio), the chitosan salt form used, the DNA/siRNA concentration, pH, serum, additives, preparation techniques of chitosan/nucleic acid particles and routes of administration. In this paper, chitosan-based formulations for the delivery of DNA and siRNA were reviewed to facilitate the process of chitosan vector development for clinical application. In addition to formulation optimization, chitosan structure modification or additive incorporation is an effective way to improve the stability of the polyplex in biological fluids, enhance targeted cell delivery and facilitate endo-lysosomal release of the complex. In summary, the transfection efficiency of chitosan-based delivery systems can be adjusted by changing formulation-related parameters.

Abstract
In this work, thermoresponsive diblock copolymers, poly[2-(2-methoxyethoxy) ethyl methacrylate]-b-poly(2-hydroxyethyl methacrylate) (PMEO(2)MA-b-PHEMA) with low polydispersity were synthesized by atomic transfer radical polymerization(ATRP). Low molecular weight (LWM) polyethylenimine (PEI, 1200Da) was then grafted to 1,1'-carbonyldiimidazole (CDI)-activated PMEO(2)MA-b-PHEMA to fabricate PEI-g-(PMEO(2)MA-b-PHEMA) (PEIMH) copolymer vectors. The LCSTs of PEIMHs with 3 and 8 grafted PEI side chains, separately termed as PEIMH-1 and PEIMH-2, were 32.5 and 38.7 degrees C in PBS solution. Variable temperature agarose retardation, Zeta potential and time-resolved fluorescence assays were performed to elucidate the temperature sensitive DNA condensation. It showed that DNA was condensed more efficiently by PEIMH, and the collapse of PMEO(2)MA chains led to more exposure of surface positive charges of PEIMH-1/pDNA complexes while temperature was above LCST. Variable temperature time-resolved fluorescence measurement of lifetimes of bound and free ethidium bromide (EB) unveiled that the population of EB at different states was dependent on temperature. At a temperature above LCST, the collapsed PMEO(2)MA polymer chains squeezed the loosely bound EB out of complex to become free species; thereby DNA was more tightly packaged by PEIMH-1. Temporary cooling was shown to improve the transfection efficiency of PEIMH-1 in COS-7 and HEK293 cell lines. The variable temperature protocol is more efficient in improving gene expression level in HEK293 cells. The transfection efficiency was equivalent or superior to that of PEI25K at an optimal weight ratio of vector/DNA. Furthermore, the cytotoxicity of PEIMH-1 was considerably lower than that of control PEI25K.

Abstract
Engineering polymeric gene-delivery vectors to release an intact DNA payload at the optimal time and subcellular compartment remains a formidable challenge. An ideal vector would provide total protection of complexed DNA from degradation prior to releasing it efficiently near or within the nucleus of a target cell. While optimization of polymer properties, such as molecular weight and charge density, has proved largely inadequate in addressing this challenge, applying polymeric carriers that respond to temperature, light, pH and redox environment to trigger a switch from a tight, protective complex to a more relaxed interaction favouring release at the appropriate time and place has shown promise. Currently, a paucity of gene carriers able to satisfy the contrary requirements of adequate DNA protection and efficient release contributes to the slow progression of non-viral gene therapy towards clinical translation. This review highlights the promising carrier designs that may achieve an optimal balance of DNA protection and release. It also discusses the imaging techniques and three-dimensional in vitro models that can help study these two barriers in the non-viral gene transfer process. Ultimately, efficacious non-viral gene therapy will depend on the combination of intelligent material design, innovative imaging techniques and sophisticated in vitro model systems to facilitate the rational design of polymeric gene-delivery vectors.

Abstract
Chitosan is a naturally occurring cationic mucopolysaccharide. It is generally biocompatible, biodegradable, mucoadhesive, non-immunogenic and non-toxic. Although chitosan is able to condense nucleic acids (NA) (both DNA and RNA) and protect them from nuclease degradation, its poor water solubility and low transfection efficacy have impeded its use as an NA carrier. In order to overcome such limitations, a multitude of strategies for chitosan modification and formulation have been proposed. In this article, we will first give a brief overview of the physical and biological properties of chitosan. Then, with a special focus on plasmid DNA delivery, we will have a detailed discussion of the latest advances in chitosan-mediated NA transfer. For future research, the following three important areas will be discussed: chitosan-mediated therapeutic small RNA transfer, structure-activity relationships (SAR) in chitosan vector design, and chitosan-mediated oral/nasal NA therapy.
