Co-delivery of hydrophilic and hydrophobic drugs by micelles: a new approach using drug conjugated PEG–PCLNanoparticles

Preparation of nano-sized multi-vesicular vesicles (MVVs) and its application in co-delivery of doxorubicin and curcumin

Multi-vesicular vesicles (MVVs) offer structural advantages in terms of drug encapsulation and physiological stability. In this study, we address the challenge of preparing small-sized MVVs for drug delivery. The nano-sized MVVs (∼120 nm) loaded with doxorubicin (DOX) and curcumin (CUR) (DOX/CUR@MVVs) were successfully prepared using a glass bead combined with a thin film dispersion method. Transmission electron microscopy (TEM) and dynamic light scattering (DLS) analysis confirmed the independent non-homocentric vesicle structures of DOX/CUR@MVVs with homogeneous particle sizes. The experimental results showed high encapsulation rates of DOX and CUR in DOX/CUR@MVVs, reaching 82.5 ± 0.75 % and 85.9 ± 0.69 %, respectively. Moreover, the MVVs exhibited good biosafety and sustained release properties. Notably, the bioavailability of DOX and CUR in DOX/CUR@MVVs was enhanced compared to free DOX and CUR, with increases of 4.2 and 2.1 times, respectively. And the half-life of DOX and CUR was extended by 10 times in DOX/CUR@MVVs. In vivo antitumor experiments demonstrated that nano-sized DOX/CUR@MVVs significantly improved the antitumor activity while reducing the toxic side effects of DOX. Overall, the successful preparation of nano-sized DOX/CUR@MVVs and their potent and low-toxic antitumor effects provide a critical experimental reference for the combined antitumor therapy of MVVs and liposomes.

Self-targeted hyaluronic acid-b-poly (β-amino ester) pH-switchable polymersome for guided doxorubicin delivery to metastatic breast cancer

In this study, a targeted pH-sensitive polymersome incorporating doxorubicin (DOX) was manufactured implementing diblock copolymer of hyaluronic acid-b-pPoly (β-amino ester) (HA-PBAE). The hydrophilic DOX was loaded into the aqueous compartment of HA-PBAE polymersomal structure during nanoprecipitation process with 60 % ± 3.0 entrapment efficiency (EE%) and 5.3 % ± 0.2 loading content (LC%) while demonstrating spherical morphology with size of 196 ± 3.8 nm and PDI of 0.3. The prepared platform (DOX-HA-PBAE) illustrated accelerated DOX release in acidic pH 5.4, and showed significantly higher cytotoxicity and cellular internalization in comparison with free DOX against 4T1 cell line (CD44 positive cell). In contrast, no significant growth inhibition was observed in CHO cell line (CD44 negative cell). Furthermore, DOX-HA-PBAE platform displayed higher therapeutic efficacy, favorable tumor accumulation and lower systemic toxicity in comparison with free DOX based on obtained experimental data in ectopic 4T1 tumor model in BALB/c Female mice in terms of tumor growth rate, survival rate, body weight loss, ex vivo biodistribution and pathological evaluations. The obtained results demonstrated that DOX-HA-PBAE polymersomes have potential to be used in metastatic breast cancer therapy with promising characteristics in terms of tumor growth suppression and safety profile.

pH/redox-responsive core cross-linked based prodrug micelle for enhancing micellar stability and controlling delivery of chemo drugs: An effective combination drug delivery platform for cancer therapy

Core-crosslinking of micelles (CCMs) appears to be a favorable strategy to enhance micellar stability and sustained release of the loaded drug. In this study, the DOX-conjugated pH-sensitive polymeric prodrug Methoxy Poly (ethylene oxide)-b-Poly (Aspartate-Hydrazide) (mPEG-P [Asp-(Hyd-DOX)] was created using ring-opening polymerization. To further enhance the micellar system, 3,3'-diselanediyldipropanoic acid (DSeDPA) was applied to link the hydrophobic segment via click reaction to form pH/redox-responsive CCMs. Dual anti-cancer drugs, DOX as a pro-drug and SN-38 as a targeting drug, were used to enhance inhibition. DLS confirmed that the non-cross-linked micelle (NCMs) showed a higher (96.43 nm) particle size compared to the CCMs (72.63 nm). Due to micellar shrinkage after crosslinking, CCMs displayed SN-38 drug loading (7.32 %) and encapsulation efficiency (86.23 %). The mPEG-P(Asp-Hyd) copolymer's in vitro cytotoxicity on HeLa and HaCaT cell lines found that 84.52 % of the cells are alive, and zebrafish (Danio rerio) embryos and larvae are highly biocompatible. The DOX/SN-38@CCMs had a sustained discharge profile in vitro, unlike the DOX/SN-38@NCMs. In DOX/SN-38@CCMs, HeLa cells were inhibited 50.90 % more than HaCaT (14.25 %) at the maximum drug dose (10 μg/mL). The CCMs successfully targeted and supplied DOX/SN-38 in HeLa cells rather than HaCaT cells, based on cellular uptake of 2D cell culture. CCMs, unlike NCMs, inhibit the growth of spheroids for extended periods of time due to the prolonged release of the loaded drug. Overall, CCMs are good-looking for use as regulated delivery of DOX/SN-38 in cancer cells because of all of these appealing characteristics.

Universal Microcarriers Based on Natural and Synthetic Polymers for Co-Delivery of Hydrophilic and Hydrophobic Compounds

Several variants of hybrid polyelectrolyte microcapsules (hPEMC) were designed and produced by modifying in situ gelation methods and layer-by-layer (LbL) techniques. All of the hPEMC designs tested in the study demonstrated high efficiency of the model hydrophilic compound loading into the carrier cavity. In addition, the microcarriers were characterized by high efficiency of incorporating the model hydrophobic compound rhodamine B isothiocyanate (RBITC) into the hydrophobic layer consisting of poly-(d,l)-lactide-co-glycolide (PLGA), oligo-(l)-lactide (OLL), oligo-(d)-lactide (OLD) and chitosan/gelatin/poly-l-lactide copolymer (CGP). The obtained microcapsules exhibited high storage stability regardless of the composition and thickness of the polyelectrolyte shell. Study of the impact of hybrid polyelectrolyte microcapsules on viability of the adhesive L929 and suspension HL-60 cell lines revealed no apparent toxic effects of hPEMC of different architecture on live cells. Interaction of hPEMC with peritoneal macrophages for the course of 48 h resulted in partial deformation and degradation of microcapsules accompanied by release of the content of their hydrophilic (BSA–fluorescein isothiocyanate conjugate (BSA-FITC)) and hydrophobic (RBITC) layer. Our results demonstrate the functional efficiency of novel hybrid microcarriers and their potential for joint delivery of drugs with different physico-chemical properties in complex therapy.

Affibody Modified G-quadruplex DNA Micelles Incorporating Polymeric 5-Fluorodeoxyuridine for Targeted Delivery of Curcumin to Enhance Synergetic Therapy of HER2 Positive Gastric Cancer

Combination chemotherapy is emerging as an important strategy for cancer treatment with decreased side effects. However, chemotherapeutic drugs with different solubility are not easy to realize co-delivery in traditional nanocarriers. Herein, an affibody modified G-quadruplex DNA micellar prodrug (affi-F/GQs) of hydrophilic 5-fluorodeoxyuridine (FUdR) by integrating polymeric FUdRs into DNA strands is developed for the first time. To achieve synergistic efficacy with hydrophobic drugs, curcumin (Cur) is co-loaded into affi-F/GQs micelles to prepare the dual drug-loaded DNA micelles (Cur@affi-F/GQs), in which affibody is employed as a targeting moiety to facilitate HER2 receptor-mediated uptake. Cur@affi-F/GQs have a small size of approximately 130 nm and exhibit excellent stability. The system co-delivers FUdR and Cur in a ratiometric manner, and the drug loading rates are 21.1% and 5.6%, respectively. Compared with the physical combination of FUdR and Cur, Cur@affi-F/GQs show higher cytotoxicity and greater synergistic effect on HER2 positive gastric cancer N87 cells. Surprisingly, Cur@affi-F/GQs significantly enhance the expression and activity of apoptosis-associated proteins in Bcl-2/Bax-caspase 8, 9-caspase 3 apoptotic pathway, which is the main factor in the death of tumor cells induced by FUdR. Overall, this nanoencapsulation is a promising candidate for the targeted co-delivery of drugs with significant differences in solubility.

pH-responsive polymer micelles for methotrexate delivery at tumor microenvironments

Methotrexate (MTX) anticancer drug was successfully loaded and released in a controlled manner from polymer micelles made of a diblock copolymer of poly(monomethoxy ethylene glycol)-b-poly(ε-caprolactone) (mPEG-PCL). The empty and MTX-loaded micelles (MTX/mPEG-PCL) were characterized by electron microscopy. The drug release dependence upon pH 5.4, 6.5, and 7.4 for 30 days was proven and characterized by UV-Vis spectroscopy. The cytotoxic effect of MTX/mPEG-PCL micelles on MCF-7 breast cancer cells was evaluated through an MTT assay. The morphological analysis indicated the successful formation of micelles of 76 and 131 nm for empty and MTX-loaded micelles, respectively. An encapsulation efficiency of 70.2% and a loading capacity of 8.8% were obtained. The in vitro release of MTX showed a gradual and sustained profile over 22 days, with a clear trend to much higher release at acidic pH (80 and 90% for pH 6.7 and 5.5, respectively). The MTX/mPEG-PCL micelles showed an IC50 of MCF-7 cells at 30 µg mL−1. The results suggested that MTX/mPEG-PCL could be a promising drug delivery system for cancer treatment.

Emerging insights on drug delivery by fatty acid mediated synthesis of lipophilic prodrugs as novel nanomedicines

Many drug molecules that are currently in the market suffer from short half-life, poor absorption, low specificity, rapid degradation, and resistance development. The design and development of lipophilic prodrugs can provide numerous benefits to overcome these challenges. Fatty acids (FAs), which are lipophilic biomolecules constituted of essential components of the living cells, carry out many necessary functions required for the development of efficient prodrugs. Chemical conjugation of FAs to drug molecules may change their pharmacodynamics/pharmacokinetics in vivo and even their toxicity profile. Well-designed FA-based prodrugs can also present other benefits, such as improved oral bioavailability, promoted tumor targeting efficiency, controlled drug release, and enhanced cellular penetration, leading to improved therapeutic efficacy. In this review, we discuss diverse drug molecules conjugated to various unsaturated FAs. Furthermore, various drug-FA conjugates loaded into various nanostructure delivery systems, including liposomes, solid lipid nanoparticles, emulsions, nano-assemblies, micelles, and polymeric nanoparticles, are reviewed. The present review aims to inspire readers to explore new avenues in prodrug design based on the various FAs with or without nanostructured delivery systems.

Co-Delivery of Paclitaxel and Doxorubicin by pH-Responsive Prodrug Micelles for Cancer Therapy

Background

It is of great significance to develop intelligent co-delivery systems for cancer chemotherapy with improved therapeutic efficacy and few side-effects.

Materials and Methods

Here, we reported a co-delivery system based on pH-sensitive polyprodrug micelles for simultaneous delivery of doxorubicin (DOX) and paclitaxel (PTX) as a combination chemotherapy with pH-triggered drug release profiles. The physicochemical properties, drug release profiles and mechanism, and cytotoxicity of PTX/DOX-PMs have been thoroughly investigated.

Results and Discussion

The pH-sensitive polyprodrug was used as nanocarrier, and PTX was encapsulated into the micelles with high drug-loading content (25.6%). The critical micelle concentration (CMC) was about 3.16 mg/L, indicating the system could form the micelles at low concentration. The particle size of PTX/DOX-PMs was 110.5 nm, and increased to approximately 140 nm after incubation for 5 days which showed that the PTX/DOX-PMs had high serum stability. With decrease in pH value, the particle size first increased, and thenwas no longer detectable. Similar change trend was observed for CMC values. The zetapotential increased sharply with decrease in pH. These results demonstrated the pHsensitivity of PTX/DOX-PMs. In vitro drug release experiments and study on release mechanism showed that the drug release rate and accumulative release for PTX and DOX were dependent on the pH, showing the pH-triggered drug release profiles. Cytotoxicity assay displayed that the block copolymer showed negligible cytotoxicity, while the PTX/DOX-PMs possessed high cytotoxic effect against several tumor cell lines compared with free drugs and control.

Conclusion

All the results demonstrated that the co-delivery system based on pH-sensitive polyprodrug could be a potent nanomedicine for combination cancer chemotherapy. In addition, construction based on polyprodrug and chemical drug could be a useful method to prepare multifunctional nanomedicine.

Well-Defined Diblock Poly(ethylene glycol)-b-Poly(ε-caprolactone)-Based Polymer-Drug Conjugate Micelles for pH-Responsive Delivery of Doxorubicin

Nanoparticles have emerged as versatile carriers for various therapeutics and can potentially treat a wide range of diseases in an accurate and disease-specific manner. Polymeric biomaterials have gained tremendous attention over the past decades, owing to their tunable structure and properties. Aliphatic polyesters have appealing attributes, including biodegradability, non-toxicity, and the ability to incorporate functional groups within the polymer backbone. Such distinctive properties have rendered them as a class of highly promising biomaterials for various biomedical applications. In this article, well-defined alkyne-functionalized poly(ethylene glycol)-b-poly(ε-caprolactone) (PEG-b-PCL) diblock copolymer was synthesized and studied for pH-responsive delivery of doxorubicin (DOX). The alkyne-functionalized PEG-b-PCL diblock copolymer was prepared by the synthesis of an alkyne-functionalized ε-caprolactone (CL), followed by ring-opening polymerization (ROP) using PEG as the macroinitiator. The alkyne functionalities of PEG-b-PCL were modified through copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) click reaction to graft aldehyde (ALD) groups and obtain PEG-b-PCL-g-ALD. Subsequently, DOX was conjugated on PEG-b-PCL-g-ALD through the Schiff base reaction. The resulting PEG-b-PCL-g-DOX polymer-drug conjugate (PDC) self-assembled into a nano-sized micellar structure with facilitated DOX release in acidic pH due to the pH-responsive linkage. The nanostructures of PDC micelles were characterized using transmission electron microscopy (TEM) and dynamic light scattering (DLS). In vitro studies of the PDC micelles, revealed their improved anticancer efficiency towards MCF-7 cells as compared to free DOX.

The Application of Nanotechnology in the Codelivery of Active Constituents of Plants and Chemotherapeutics for Overcoming Physiological Barriers during Antitumor Treatment

Antitumor therapy using a combination of drugs has shown increased clinical efficacy. Active constituents derived from plants can offer several advantages, such as high efficiacy, low toxicity, extensive effects, and multiple targets. At present, the combination of plants' active constituents and chemotherapeutic drugs has attracted increased attention. Nanodrug delivery systems (NDDSs) have been widely used in tumor-targeted therapy because of their efficacy of delivering antitumor drugs. The in vivo process of tumor-targeted NDDSs has several steps. They include blood circulation, tumor accumulation and penetration, target cell internalization and uptake, and drug release and drug response. In each step, NDDSs encounter multiple barriers that prevent their effective delivery to target sites. Studies have been performed to find alternative strategies to overcome these barriers. We reviewed the recent progress of codelivery of active constituents of plants and chemotherapeutics using NDDSs. Progress into transversing the physiological barriers for more effective in vivo antitumor delivery will be discussed in this review.

Mannosylated brush copolymers based on poly(ethylene glycol) and poly(ε-caprolactone) as multivalent lectin-binding nanomaterials

A class of linear and four-arm mannosylated brush copolymers based on poly(ethylene glycol) and poly(ε-caprolactone) is presented here. The synthesis through ring-opening and atom transfer radical polymerizations provided high control over molecular weight and functionality. A post-polymerization azide-alkyne cycloaddition allowed for the formation of glycopolymers with different mannose valencies (1, 2, 4, and 8). In aqueous media, these macromolecules formed nanoparticles that were able to bind lectins, as investigated by concanavalin A binding assay. The results indicate that carbohydrate-lectin interactions can be tuned by the macromolecular architecture and functionality, hence the importance of these macromolecular properties in the design of targeted anti-pathogenic nanomaterials.

Chitosan-collagen based film for controlled delivery of a combination of short life anesthetics

The present research was undertaken to develop a chitosan-collagen film for controlled delivery of combinations of local anesthetics. The film has been prepared by casting which is a versatile, rapid and low-cost approach distinguished by high reproducibility. The mechanical, morphological, and physicochemical properties of the films and the impact of the drug loading were evaluated. We showed that the formulations have a good combination of strength and flexibility with high water permeability. Surface morphology investigation indicates a variation in roughness depending on the loaded compound. Release studies were performed in controlled environments and the data processed by the Higuchi model to assess the dynamics of the release. The local anesthetics, lidocaine, tetracaine, and benzocaine, were uniformly distributed within the matrix and released in a rate and magnitude specific for the drug concentration and combination tunable in a range time from 6 h to 24 h. The films dissolve completely in the physiological environment within 24 h without leaving any toxic metabolites as both of the components are recognized as safe. In vitro cytotoxicity and cell proliferation tests performed on human dermal fibroblast demonstrate the biocompatibility and lack of cytotoxicity of the prepared formulations.

Diosgenin-conjugated PCL–MPEG polymeric nanoparticles for the co-delivery of anticancer drugs: design, optimization, in vitro drug release and evaluation of anticancer activity

In this study, a polymeric nanoparticle-mediated dual anti-cancer drug delivery system was designed and developed.

Preparation, characterisation, and controlled release of sex pheromone-loaded MPEG-PCL diblock copolymer micelles for Spodoptera litura (Lepidoptera: Noctuidae)

Sex pheromones are important for agricultural pest control. The main sex pheromone components of Spodoptera litura are (Z,E)-9,11- and (Z,E)-9,12-tetradecadienyl acetate (Z9,E11-14:Ac; Z9,E12-14:Ac). In this study, we investigated the optimal conditions for encapsulation of S. litura sex pheromonesin micelles via the self-assembly method using monomethoxy poly (ethylene glycol)-poly (ε-caprolactone) (MPEG-PCL) as a biodegradable wall-forming material with low toxicity. In the L₉(3⁴) orthogonal experiment, 3 amphiphilic block copolymers, with different hydrophilicity to hydrophobicity ratios, were examined. Optimal encapsulation conditions included stirring of MPEG₅₀₀₀-PCL₂₀₀₀ at 1000 rpm at 30°C with 2.5:1 wall-forming: core material mass ratio. S. litura sex pheromone-loaded MPEG₅₀₀₀-PCL₂₀₀₀ micelles presented a homogeneous spherical morphology with apparent core-shell structure. The release kinetics of optimized MPEG₅₀₀₀-PCL₂₀₀₀ micelles was best explained by a first-order model. Encapsulated Z9,E11-14:Ac and Z9,E12-14:Ac were released slowly, not suddenly. Methyl oleate (MO) was used as an agent to control micellar release performance. When MO content equalled block content, micelle half-life could be prolonged, thereby controlling the release speed. Overall, our results showed MPEG-PCL as a promising controlled-release substrate for sex pheromones.

Preparation of biocompatible copolymeric micelles as a carrier of atorvastatin and rosuvastatin for potential anticancer activity study

Statins are widely used for the treatment of hypercholesterolemia. However, their inhibitory action on HMG-CoA reductase also results in the depletion of intermediate biosynthetic products, which importantly contribute to cell proliferation. The aim of the present study was to compare the effects of the individual commercially available statins on investigational breast cancer. Thus, in this study, biodegradable polymeric micelles as carrier of statins were prepared using biodegradable copolymers (PCL-PEG-PCL). These nanoparticles were prepared with two statins (atorvastatin and rosuvastatin) and drug loading, release, kinetic release, and anti-cancer activity of these drugs were studied. The triblock copolymer PCL-PEG-PCL was synthesized by a ring opening polymerization of e-caprolactone in the presence of PEG as the initiator and Sn(oct)₂ as the catalyst. The synthesized copolymers and nanoparticles were characterized by FTIR, HNMR, GPC, DLS, and AFM analyses. The drug loading and release of drugs were studied by UV-Vis. Additionally, MTT assays on HFF-2 cell lines were performed for determination of biocompatibility of micelles. Finally, the anticancer activity of micelles was studied on MCF-7 breast cancer cell lines. The results showed that the average diameter of nanoparticles was less than 45 nm. The loading capacity of atorvastatin and rosuvastatin was 20.0 ± 1.01% and 13.21 ± 1.18%, respectively, and encapsulation efficiency of atorvastatin and rosuvastatin was 88.19 ± 1.11% and 69.32 ± 0.23%, respectively. The results showed strong and dose-dependent inhibition of cell (MCF-7line) growth by the nanoparticles compared with statins. The result of cell viability assay on the MCF-7 cell line verified that the bare nanoparticles showed little inherent cytotoxicity whereas the statins-loaded nanoparticles were cytotoxic.

Facile synthesis of pH-responsive polymersomes based on lipidized PEG for intracellular co-delivery of curcumin and methotrexate

pH-responsive polymersomes were obtained by self-assembling of a carboxyl-terminated PEG amphiphile achieved via esterification of PEG diacid with PEG40stearate. The obtained vesicular systems had spherical shape and a mean diameter of 70 nm. The pH sensitivity was assessed by measuring the variations of particles mean diameter after incubation in media mimicking the physiological (pH 7.4) or tumor (pH 5.0) conditions, recording a significant increase of the vesicles dimensions at acidic pH. The ability of the polymersomes to carry both hydrophobic and hydrophilic drugs was evaluated by loading the vesicles with curcumin and methotrexate, respectively, obtaining high encapsulation efficiencies and pH-dependent release profiles. The drug-loaded polymeric vesicles exhibited improved cytotoxic potential against MCF-7 cancer cell line and were found to be highly hemocompatible. Finally, cellular uptake experiments on MCF-7 cancer cells were conducted to demonstrate the ability of the designed polymersomes to enhance drug penetration inside the cells.

Methotrexate-conjugated mPEG–PCL copolymers: a novel approach for dual triggered drug delivery

A conjugate of the antitumor drug, methotrexate (MTX), with a diblock methoxypoly(ethylene glycol)–poly(caprolactone) (mPEG–PCL) copolymer was synthesized by the reaction of the mPEG–PCL copolymer with MTX in the presence of dicyclohexylcarbodiimide and dimethylaminopyridine.

In vitro and in vivo delivery of atorvastatin: A comparative study of anti-inflammatory activity of atorvastatin loaded copolymeric micelles

Statins have been shown to exert ‘pleiotropic effects’ independent of their cholesterol lowering actions that include anti-inflammatory properties. In this study we synthesized mono methoxy poly (ethylene glycol)–poly (ε-caprolactone) (mPEG-PCL) di block copolymers. The structure of the copolymers was characterized by H nuclear magnetic resonance, Fourier-transform infrared spectroscopy, differential scanning calorimetry and gel permeation chromatography techniques. In this method, atorvastatin was encapsulated within micelles through a single-step nano-precipitation method, leading to the formation of atorvastatin-loaded mPEG-PCL (atorvastatin/mPEG-PCL) micelles. The resulting micelles were characterized further by various techniques such as dynamic light scattering and atomic force microscopy. In this study the anti-inflammatory activity of atorvastatin and atorvastatin/mPEG-PCL micelles on acute models of inflammation are analyzed, to compare the effect of indometacin in rats. Carrageenan induces rat paw edema; six animals of each group (10 groups) received indometacin, atorvastatin, and atorvastatin/mPEG-PCL micelles orally 1, 6, 12 and 24 h before carrageenan injection in paw. The paw edema thickness measured at 1, 2, 3 and 4 h after injection and percentage inhibition of edema in various groups were calculated. The results showed that the zeta potential of micelles was about −16.6 mV and the average size was 81.7 nm. Atorvastatin was encapsulated into mPEG-PCL micelles with loading capacity of 14.60 ± 0.96% and encapsulation efficiency of 62.50 ± 0.84%. Atorvastatin and atorvastatin/mPEG-PCL micelles showed significant anti-inflammatory activity in the present study. The anti-inflammatory activity of atorvastatin and atorvastatin/mPEG-PCL micelles was significant in comparison with indometacin. Atorvastatin/mPEG-PCL micelles showed more anti-inflammatory activity than atorvastatin. This study revealed the anti-inflammatory activity of atorvastatin and atorvastatin/mPEG-PCL micelles and suggested the statins have a potential inflammatory activity along with its lipid lowering properties. Contrary to anti-inflammatory effects, the pro-inflammatory responses are independent of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibition and can be mediated directly by atorvastatin.

Preparation of magnetic albumin nanoparticles via a simple and one-pot desolvation and co-precipitation method for medical and pharmaceutical applications

In this study, iron oxide magnetic bovine serum albumin core-shell nanoparticles (BSA coated IONPs) with narrow particle size distribution were synthesized under one-pot reaction via the desolvation and chemical co-precipitation method. Functionalized IONPs were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM) techniques. Furthermore, vibrating sample magnetometer (VSM) analysis show these nanoparticles (NPs) have an excellent magnetic properties. Cellular toxicity of IONPs was also investigated on HFF2 cell lines. Additionally, a hemolysis test of as prepared core-shell NPs were performed. The presence of albumin as a biomolecule coating on the surface of IONPs showed an improving effect to reduce the cytotoxicity. The properties of the designed NPs propose the BSA coated IONPs as a promising candidate for multifunctional biomedical applications.
