Abstract
In this investigation, low molecular weight polyethyleneimine (LMW PEI; 1.8 kDa branched PEI) was conjugated to phathalated dextrin. The aim of this chemical modification was to decorate PEI molecules with a hydrophilic layer to improve its biophysical properties while the phthalic moiety may improve the hydrophilic-hydrophobic balance of the final structure. The polymers were prepared at various conjugation degrees ranging from 6.5% to 16.5% and characterized in terms of biophysical characteristics as well as their gene transfer ability and cell-induced toxicity. The results showed that dextrin-phthalated-PEI (DPHPEI) polymer was able to form nanoparticles with the size range of around 118-170 nm, with the zeta potential of 6.2-9.5 mV. DPHPEI polymers could increase the level of desired protein expression in the cells by up to three folds compared with unmodified LMW PEI while the cell viability of the modified polymers was around 80%. The result of this study shows a promising approach to improve the transfection efficiency of LMW PEI while maintaining its low toxic effects.

Abstract
Nanogels represent promising drug delivery systems in the biomedical field, designed to overcome challenges associated with standard treatment approaches. Stimuli-responsive nanogels, often referred to as intelligent materials, have garnered significant attention for their potential to enhance control over properties such as drug release and targeting. Furthermore, researchers have recently explored the application of nanogels in diverse sectors beyond biomedicine including sensing materials, catalysts, or adsorbents for environmental applications. However, to fully harness their potential as practical delivery systems, further research is required to better understand their pharmacokinetic behaviour, interactions between nanogels and bio distributions, as well as toxicities. One promising future application of stimuli-responsive multifunctional nanogels is their use as delivery agents in cancer treatment, offering an alternative to overcome the challenges with conventional approaches. This review discusses various synthetic methods employed in developing nanogels as efficient carriers for drug delivery in cancer treatment. The investigations explore, the key aspects of nanogels, including their multifunctionality and stimuli-responsive properties, as well as associated toxicity concerns. The discussions presented herein aim to provide the readers a comprehensive understanding of the potential of nanogels as smart drug delivery systems in the context of cancer therapy.

Abstract
Owing to the distinctive constituents of tumor tissue from those healthy organs, nanomedicine strategies show significant potentials in smart drug delivery. Nowadays, stimuli-responsive nanogels are playing increasingly important roles in the application of cancer therapy because of their sensitivity to various internal or external physicochemical stimuli, which exhibit site-specific and markedly enhanced drug release. Besides, nanogels are promising as drug carriers because of their porous structures, good biocompatibility, large surface area, and excellent capability with drugs. Taking advantage of multiresponsiveness, recent years have witnessed the rapid evolution of stimulus-responsive nanogels from monoresponsive to multiresponsive systems; however, there lacks a comprehensive review summarizing these reports. In this Review, we discuss the properties, synthesis, and characterization of nanogels. Moreover, tumor microenvironment and corresponding designing strategies for stimuli-response nanogels, both exogenous (temperature, magnetic field, light) and endogenous (pH, biomolecular, redox, ROS, pressure, hypoxia) are summarized on the basis of the recent advances in multistimuli-responsive nanogel systems. Nanogel and two-dimensional material composites show excellent performance in the field of constructing multistimulus-responsive nanoparticles and precise intelligent drug release integrated system for multimodal cancer diagnosis and therapy. Finally, potential progresses and suggestions are provided for the further design of hybrid nanogels based on emerging two-dimensional materials.

Abstract
Novel biocompatible and brush copolymers have been developed for cancer treatment using its controlled drug-release potential. Polyurethane graft on linear dextrin has been synthesized to control the hydrophilic-hydrophobic balance for regulated drug delivery. The properties of the graft copolymers have been tuned through graft density. The prepared grafts are thermally stable and mechanically strong. An injectable hydrogel has been developed by embedding the drug-loaded brush copolymers in methyl cellulose to better control the release for a prolonged period, importantly by keeping the drug release at a constant rate. Cellular studies indicate the biocompatible nature of the brush copolymers whose controlled and slow release of drug exhibit significant cytotoxic effects on cancer cells. Endocytosis of drug tagged contrast agent indicates greater transport of biologically active material inside cell as observed through cellular uptake studies. In vivo studies on melanoma mice exhibit the real efficacy of the controlled drug release from the injectable hydrogel with significant melanoma suppression without any side effects as opposed to severe toxic effects observed in conventional chemotherapy. Special application method of drug-loaded hydrogel just beneath the tumor makes this system incredibly effective through confinement. Thus, brush copolymer injectable hydrogel is a promising vehicle for control release of drug for cancer treatment in future.

Abstract
Different synthetic strategies were tested for the incorporation of galactose molecules on thermoresponsive nanogels owing to their affinity for receptors expressed in cancer cells. Three families of galactose-functionalized poly(N-vinylcaprolactam) nanogels were prepared with the aim to control the introduction of galactose-moieties into the core, the core-shell interface and the shell. First and second of the above mentioned, were prepared via surfactant free emulsion polymerization (SFEP) by a free-radical mechanism and the third one, via SFEP/reversible addition-fragmentation chain transfer (RAFT) polymerization. Synthetic recipes for the SFEP/free radical method included besides N-vinylcaprolactam (NVCL), a shell forming poly(ethylene glycol) methyl ether methacrylate (PEGMA), while the galactose (GAL) moiety was introduced via 6-O-acryloyl-1,2,:3,4-bis-O-(1-methyl-ethylidene)-α-D-galactopiranose (6-ABG, protected GAL-monomer): nanogels I, or 2-lactobionamidoethyl methacrylate (LAMA, GAL-monomer): nanogels II. For the SFEP/RAFT methodology poly(2-lactobionamidoethyl methacrylate) as GAL macro-chain transfer agent (PLAMA macro-CTA) was first prepared and on a following stage, the macro-CTA was copolymerized with PEGMA and NVCL, nanogels III. The crosslinker ethylene glycol dimethacrylate (EGDMA) was added in both methodologies for the polymer network construction. Nanogel's sizes obtained resulted between 90 and 370 nm. With higher content of PLAMA macro-CTA or GAL monomer in nanogels, a higher the phase-transition temperature (TVPT) was observed with values ranging from 28 to 46 °C. The ρ-parameter, calculated by the ratio of gyration and hydrodynamic radii from static (SLS) and dynamic (DLS) light scattering measurements, and transmission electron microscopy (TEM) micrographs suggest that core-shell nanogels of flexible chains were obtained; in either spherical (nanogels II and III) or hyperbranched (nanogels I) form.

Abstract
The presented work aimed to test influence of poly(L-lactide-co-glycolide)-block-poly (ethylene oxide) copolymer modification by blending with grafted dextrin or maltodextrin on the course of degradation in soil and the usefulness of such material as a matrix in the controlled release of herbicides. The modification should be to obtain homogenous blends with better susceptibility to enzymatic degradation. Among all tested blends, which were proposed as a carrier for potential use in the controlled release of plant protection agents, PLGA-block-PEG copolymer blended with grafted dextrin yielded very promising results for their future applications, and what is very importantly proposed formulations provide herbicides in unchanged form into soil within few months of release. The modification PLAGA/PEG copolymer by blending with modificated dextrins affects the improvement of the release profile. The weekly release rates for both selected herbicides (metazachlor and pendimethalin) were constant for a period of 12 weeks. Enzymatic degradation of modified dextrin combined with leaching of the degradation products into medium caused significant erosion of the polymer matrix, thereby leading to acceleration of water diffusion into the polymer matrix and allowing for easier leaching of herbicides outside the matrix.

Abstract
This review investigates the significant role polysaccharide particles play in functional drug delivery. The importance of these systems is due to the wide variety of polysaccharides and their natural source meaning that they can provide biocompatible and biodegradable systems with a range of both biological and chemical functionality valuable for drug delivery. This functionality includes protection and presentation of working therapeutics through avoidance of the reticuloendothelial system, stabilization of biomacromolecules and increasing the bioavailability of incorporated small molecule drugs. Transport of the therapeutic is also key to the utility of polysaccharide particles, moving drugs from the site of administration through mucosal binding and transport and using chemistry, size and receptor mediated drug targeting to specific tissues. This review also scrutinizes the methods of synthesizing and constructing functional polysaccharide particle drug delivery systems that maintain and extend the functionality of the natural polysaccharides.

Abstract
The worldwide incidence of bone disorders is raising, mainly due to aging population. The lack of effective treatments is pushing the development of synthetic bone substitutes (SBSs). Most ceramic-based SBSs commercially available display limited handling properties. Attempting to solve these issues and achieve wider acceptance by the clinicians, granular ceramics have been associated with hydrogels (HGs) to produce injectable/moldable SBSs. Dextrin, a low-molecular-weight carbohydrate, was used to develop a fully resorbable and injectable HG. It was first oxidized with sodium periodate and then cross-linked with adipic acid dihydrazide. The in vivo biocompatibility and safety of the dextrin-based HG was assessed by subacute systemic toxicity and skin sensitization tests, using rodent models. The results showed that the HG did not induce any systemic toxic effect, skin reaction, or genotoxicity, neither impaired the bone repair/regeneration process. Then, the HG was successfully combined with granular bone substitute, registered as Bonelike (250-500 μm) to obtain a moldable/injectable SBS, which was implanted in tibial fractures in goats for 3 and 6 weeks. The obtained results showed that HG allowed the stabilization of the granules into the defect, ensuring effective handling, and molding properties of the formulation, as well as an efficient cohesion of the granules. © 2019 Wiley Periodicals, Inc.

Abstract
The traditional drug delivery techniques are unresponsive to the altering metabolic states of the body and fail to achieve target specific drug delivery, which results in toxic plasma concentrations. In order to harmonize the drug release profiles, diverse biological and pathological pathways and factors involved have been studied and consequently, nanomaterials and nanostructures are engineered in a manner so that they respond and interact with the target cells and tissues in a controlled manner to induce promising pharmacological responses with least undesirable effects. The bioinspired nanoparticles such as carbon nanotubes, metallic nanoparticles, and quantum dots sense the localized host environment for diagnosis and treatment of pathological states. These biocompatible polymeric- based nanostructures bind drugs to the specific receptors, which renders them as ideal vehicles for the delivery of drugs and gene. The ultimate goal of bioinspired nanocomposites is to achieve personalized diagnostic and therapeutic outcomes. This review briefly discussed current trends; role, recent advancements as well as different approaches, which are being used for designing and fabrication of some bioinspired nanocarriers.

Abstract
HYPOTHESIS Polymeric micelles are fabricated by the self-aggregation of amphiphilic polymers in aqueous medium. Amphiphilic block copolymers consist of hydrophobic and hydrophilic blocks. The hydrophilic blocks form corona, while hydrophobic blocks produce core of the micelle. EXPERIMENTS In the present manuscript, a triblock copolymer derived from poly (ethylene glycol) and poly (vinyl acetate) (PVAc-b-PEG200-b-PVAc) has been prepared via reversible addition-fragmentation chain transfer polymerization. Its structural properties as well as micellar stability have been studied and application as dye carrier has been discussed in details. FINDINGS The GPC analysis shows the low polydispersity of the developed copolymer that signifies the controlled nature of polymerization. The copolymer demonstrates long-term micellar stability, which has been determined by dynamic light scattering (DLS) analysis. The block copolymer reveals excellent pH-triggered release behavior of loaded Nile red, which ascertained the dye carrier feature of PVAc-b-PEG200-b-PVAc.

Abstract
Recently, a novel biopolymeric nanocomposite hydrogel comprised of in situ formed silver nanowires (AgNWs) deposited chemically cross-linked carboxymethyl cellulose (CMC) has been developed, which demonstrates superior efficacy as anticancer drug-curcumin carrier. The cross-linked polymer has been prepared by grafting poly [2-(methacryloyloxy) ethyl trimethylammonium chloride] on CMC using diethylene glycol dimethacrylate cross-linker. The nanocomposite hydrogel has the capability to encapsulate both hydrophobic/hydrophilic transdermal drugs. With variation in reaction conditions/parameters, several composite materials have been synthesized and depending on lower swelling/higher cross-linking and greater gel strength, an optimized grade of nanocomposite hydrogel has been selected. The developed nanocomposite hydrogel is characterized with FTIR/NMR spectra, FESEM/XRD/TGA/AFM/XPS analyses, and UV-visible spectroscopy. Rheological study has been performed to enlighten the gel strength of the composite material. The synthesized nanocomposite hydrogel is biodegradable and nontoxic to mesenchymal stem cells (hMSCs). In vitro release of curcumin suggests that in situ incorporation of AgNWs on cross-linked CMC enhanced the penetration power of nanocomposite hydrogel and released the drug in sustained way (∼62% for curcumin released in 4 days). Ex vivo rat skin permeation study confirms that the drug from both the cross-linked and nanocomposite hydrogel was permeable through the rat skin in controlled fashion. Additionally the curcumin loaded composite hydrogel can efficiently kill the MG 63 cancer cells, which has been confirmed by apoptosis study and therefore, probably be a suitable carrier for curcumin delivery toward cancer cells.

Abstract
The present article demonstrates the targeted delivery of doxorubicin hydrochloride to human osteosarcoma cancer cell lines (MG 63) using functionalized dextrin based crosslinked, pH responsive and biocompatible nanogel. The nanogel has been prepared through Michael-type addition reaction using dextrin (Dxt), N, N'-methylene bisacrylamide (MBA, as crosslinker), acrylic acid (AA, as monomer) and potassium persulfate (KPS, as initiator). The structure, composition, morphology of the nanogel have been explored using FTIR and 1H NMR spectroscopy, XRD, TGA, DSC, CHN and AFM analyses. The TEM analysis confirmed that the size of nanogel appeared within 100nm, while DLS study indicates that the diameter of the nanogel remained between 113 and 126nm. The AFM study implied the porous morphology of the synthesized nanogel. The rheological study suggests the gel behaviour of the synthesized nanogel at 37±0.1°C. Difference in% swelling at pH 5.5 and 7.4 indicates pH-responsiveness of the nanogel. The in vitro cytocompatibility results ascertained that the nanogel is non-toxic to human mesenchymal stem cells (hMSCs). In vitro cellular uptake study confirmed that FITC-loaded nanogel can cross the cellular membrane and be well uptake by the cell cytoplasm. The nanogel could efficiently encapsulate doxorubicin hydrochloride (Dox) with the loading efficiency of 27±0.2% after 72h. The Dox-loaded nanogel demonstrates anti-cancer activity towards MG 63 cancer cells and release the encapsulated drug in a controlled way.
