Development of Polymer-Encapsulated, Amine-Functionalized Zinc Ferrite Nanoparticles as MRI Contrast Agents. Int J Mol Sci 2023; 24:16203. [PMID: 38003394 PMCID: PMC10671131 DOI: 10.3390/ijms242216203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 11/07/2023] [Accepted: 11/08/2023] [Indexed: 11/26/2023] Open
Abstract
The need for stable and well-defined magnetic nanoparticles is constantly increasing in biomedical applications; however, their preparation remains challenging. We used two different solvothermal methods (12 h reflux and a 4 min microwave, MW) to synthesize amine-functionalized zinc ferrite (ZnFe2O4-NH2) superparamagnetic nanoparticles. The morphological features of the two ferrite samples were the same, but the average particle size was slightly larger in the case of MW activation: 47 ± 14 nm (Refl.) vs. 63 ± 20 nm (MW). Phase identification measurements confirmed the exclusive presence of zinc ferrite with virtually the same magnetic properties. The Refl. samples had a zeta potential of -23.8 ± 4.4 mV, in contrast to the +7.6 ± 6.8 mV measured for the MW sample. To overcome stability problems in the colloidal phase, the ferrite nanoparticles were embedded in polyvinylpyrrolidone and could be easily redispersed in water. Two PVP-coated zinc ferrite samples were administered (1 mg/mL ZnFe2O4) in X BalbC mice and were compared as contrast agents in magnetic resonance imaging (MRI). After determining the r1/r2 ratio, the samples were compared to other commercially available contrast agents. Consistent with other SPION nanoparticles, our sample exhibits a concentrated presence in the hepatic region of the animals, with comparable biodistribution and pharmacokinetics suspected. Moreover, a small dose of 1.3 mg/body weight kg was found to be sufficient for effective imaging. It should also be noted that no toxic side effects were observed, making ZnFe2O4-NH2 advantageous for pharmaceutical formulations.

Abstract
The paradigm of drug delivery via particulate formulations is one of the leading ideas that enable overcoming limitations of traditional chemotherapeutic agents. The trend toward more complex multifunctional drug carriers is well-traced in the literature. Nowadays, the prospectiveness of stimuli-responsive systems capable of controlled cargo release in the lesion nidus is widely accepted. Both endogenous and exogenous stimuli are employed for this purpose; however, endogenous pH is the most common trigger. Unfortunately, scientists encounter multiple challenges on the way to the implementation of this idea related to the vehicles' accumulation in off-target tissues, their immunogenicity, the complexity of drug delivery to intracellular targets, and finally, the difficulties in the fabrication of carriers matching all imposed requirements. Here, we discuss fundamental strategies for pH-responsive drug delivery, as well as limitations related to such carriers' application, and reveal the main problems, weaknesses, and reasons for poor clinical results. Moreover, we attempted to formulate the profiles of an "ideal" drug carrier in the frame of different strategies drawing on the example of metal-comprising materials and considered recently published studies through the lens of these profiles. We believe that this approach will facilitate the formulation of the main challenges facing researchers and the identification of the most promising trends in technology development.

Abstract
A protein-polymer conjugate combines the chemical properties of a synthetic polymer chain with the biological properties of a protein. In this study, the initiator terminated with furan-protected maleimide was first synthesized through three steps. Then, a series of zwitterionic poly[3-dimethyl(methacryloyloxyethyl)ammonium propanesulfonate] (PDMAPS) was synthesized via atom transfer radical polymerization (ATRP) and optimized. Subsequently, well-controlled PDMAPS was conjugated with keratin via thiol-maleimide Michael addition. The keratin-PDMAPS conjugate (KP) could self-assemble in an aqueous solution to form micelles with low critical micelle concentration (CMC) values and good blood compatibility. The drug-loaded micelles exhibited triple responsiveness to pH, glutathione (GSH), and trypsin under tumor microenvironments. In addition, these micelles showed high toxicity against A549 cells while low toxicity on normal cells. Furthermore, these micelles performed prolonged blood circulation.

Abstract
Two-dimensional transition metal dichalcogenides have attracted widespread attention in cancer theranostics due to their high specific surface area and excellent photothermal conversion properties. However, their dimensions and biodegradability have limited the exploration of the therapeutic properties of transition metal dichalcogenides. Herein, we explore the mechanism of the keratin α-helix-to-random coil transition, as an actuation mechanism for the controllable design and precise synthesis of two-dimension copper sulfide nanoflakes (CuS NFs) with high absorption in the NIR-II window. Upon mixing keratin and Cu2+, the hydrogen bonds that maintain the α-helix are broken by copper ions to form biuret coordination, while the structure of the α-helix is transformed into a random coil, providing a more scalable space for the growth of CuS NFs. The CuS NFs prepared in this way possess the great advantages of outstanding uniformity, size controllability, and biodegradability. Importantly, the CuS NFs in the NIR-II window show an excellent photothermal conversion efficiency (32.9%) and extraordinary photoacoustic signal. This work updates the fabrication of two-dimensional transition metal dichalcogenides and greatly enhances their competitiveness in the area of cancer theranostics in the NIR-II region, and provides significant theoretical and practical opportunities for the development of keratin using biomimetic synthesis.

Abstract
Keratin is a structural protein of mammalian tissues and birds, representing the principal constituent of hair, nails, skin, wool, hooves, horns, beaks, and feathers, and playing an essential role in protecting the body from external harassment. Due to its intrinsic features such as biocompatibility, biodegradability, responsiveness to specific biological environment, and physical–chemical properties, keratin has been extensively explored in the production of nanocarriers of active principles for different biomedical applications. In the present review paper, we aimed to give a literature overview of keratin-based nanoparticles produced starting from human hair, wool, and chicken feathers. Along with the chemical and structural description of keratin nanoparticles, selected in vitro and in vivo biological data are also discussed to provide a more comprehensive framework of possible fields of application of this protein. Despite the considerable number of papers describing the production and use of keratin nanoparticles as carries of anticancer and antimicrobial drugs or as hemostatic and wound healing materials, still, efforts are needed to implement keratin nanoparticles towards their clinical application.

Abstract
Injectable hydrogels hold promise in biomedical applications due to their noninvasive administration procedure and capacity enabling the filling of irregularly shaped defects. Protein-based hydrogels provide features including good biocompatibility and inherent biofunction. However, challenges still remain to develop a protein-based injectable hydrogel in a convenient way due to the limited active groups in proteins. Keratins are a group of cysteine-rich structural proteins found abundantly in skin and skin appendages. In this work, we utilized keratin and the Au(iii) salt to develop an injectable hydrogel based on the dynamic exchange between disulfide bonds (S-S) and gold(i)-thiolates (Au-S). Such a hydrogel could be prepared at the physiological pH and applied as an injectable hydrogel for biomedical applications including hemostatic and wound dressing materials. Our findings demonstrated that this keratin injectable hydrogel showed a good hemostatic effect in both tail amputation and liver injury models. Moreover, it was proved efficient as a drug loading carrier, and the deferoxamine-loaded hydrogel showed a desirable wound healing effect in a full-thickness excision wound model.

Abstract
PURPOSE The aims of this study were to test the feasibility, targeting specificity and anticancer therapeutic efficacy of CendR motif tLyP-1 functionalized at the N-terminal of ferritin for paclitaxel (PTX) delivery. METHODS A tumor homing and penetrating peptide tLyP-1 was fused to the N-terminal of human H chain ferritin (HFtn) to generate a dual-targeting nanoparticle delivery system. PTX molecules were encapsulated into the HFtn nanocage using the disassembly/assembly method by adjusting pHs. Cellular uptake was examined by confocal laser scanning microscopy (CLSM) and flow cytometry. The MTT assay was used to test the cytotoxicity of various PTX-loaded NPs against MDA-MB-231 and SMMC-7721 tumor cells. The wound healing and cell migration assays were conducted to assess the inhibitory effect on cell motility and metastasis. The inhibition effect on the SMMC-7721 tumor spheroids was studied and penetration ability was evaluated by CLSM. The antitumor efficacy of PTX-loaded NPs was assessed in MDA-MB-231 breast cancer xenografted in female BALB/c nude mice. RESULTS Compared with HFtn-PTX, in vitro studies demonstrated that the tLyP-1-HFtn-PTX displayed enhanced intracellular delivery and better cytotoxicity and anti-invasion ability against both SMMC-7721 and MDA-MB-231 cells. The better penetrability and growth inhibitory effect on SMMC-7721 tumor spheroids were also testified. In vivo distribution and imaging demonstrated that the tLyP-1-HFtn-PTX NPs were selectively accumulated and penetrated at the tumor regions. Verified by the breast cancer cells model in BABL/c nude mice, tLyP-1-HFtn-PTX displayed higher in vivo therapeutic efficacy with lower systemic toxicity. CONCLUSION Ferritin decorated with tumor-homing penetration peptide tLyP-1 at the N terminal could deliver PTX specifically inside the cell via receptor-mediated endocytosis with better efficacy. The peptide tLyP-1 which is supposed to work only at the C terminus showed enhanced tumor tissue penetration and antitumor efficacy, demonstrating that it also worked at the N-terminal of HFtn.

Abstract
Drug-loaded nanoparticles have been widely used in the field of tumor treatment due to their low side effects and reduced frequency of administration. In this study, keratin-dopamine conjugate was first synthesized by amidation reaction and then formed nanoparticles by self-polymerization of dopamine segment. Keratin-dopamine conjugate nanoparticles (KNPs) exhibited pH and glutathione (GSH) dual responsiveness in the simulated tumor environment. These nanoparticles were able to load anti-cancer drug doxorubicin (DOX) through electrostatic interactions and hydrogen bonds. These drug-loaded KNPs (DKNPs) exhibited controlled drug release in a tumor simulation environment. Meanwhile, DKNPs performed a stronger inhibitory effect on tumor cells compared with human normal tissue cells. Based on the above results, keratin-dopamine conjugate based drug carriers had a broad prospect in the field of cancer treatment.

Abstract
Iron oxide nanoparticles (IONPs) have emerged as a promising alternative to conventional contrast agents (CAs) for magnetic resonance imaging (MRI). They have been extensively investigated as CAs due to their high biocompatibility and excellent magnetic properties. Furthermore, the ease of functionalization of their surfaces with different types of ligands (antibodies, peptides, sugars, etc.) opens up the possibility of carrying out molecular MRI. Thus, IONPs functionalized with epithelial growth factor receptor antibodies, short peptides, like RGD, or aptamers, among others, have been proposed for the diagnosis of various types of cancer, including breast, stomach, colon, kidney, liver or brain cancer. In addition to cancer diagnosis, different types of IONPs have been developed for other applications, such as the detection of brain inflammation or the early diagnosis of thrombosis. This review addresses key aspects in the development of IONPs for MRI applications, namely, synthesis of the inorganic core, functionalization processes to make IONPs biocompatible and also to target them to specific tissues or cells, and finally in vivo studies in animal models, with special emphasis on tumor models.

Abstract
The blood-brain barrier (BBB) is the most important obstacle to improving the clinical outcomes of diagnosis and therapy of glioblastoma. Thus, the development of a novel nanoplatform that can efficiently traverse the BBB and achieve both precise diagnosis and therapy is of great importance. Herein, an intelligent nanoplatform based on holo-transferrin (holo-Tf) with in situ growth of MnO2 nanocrystals is constructed via a reformative mild biomineralization process. Furthermore, protoporphyrin (ppIX), acting as a sonosensitizer, is then conjugated into holo-Tf to obtain MnO2 @Tf-ppIX nanoparticles (TMP). Because of the functional inheritance of holo-Tf during fabrication, TMP can effectively traverse the BBB for highly specific magnetic resonance (MR) imaging of orthotopic glioblastoma. Clear suppression of tumor growth in a C6 tumor xenograft model is achieved via sonodynamic therapy. Importantly, the experiments also indicate that the TMP nanoplatform has satisfactory biocompatibility and biosafety, which favors potential clinical translation.

Abstract
The nano-oxide materials with special structures prepared by template methods have a good dispersion, regular structures and high specific surface areas. Therefore, in some areas, improved properties are observed than conventional bulk oxide materials. For example, in the treatment of dye wastewater, the treatment efficiency of adsorbents and catalytic materials prepared by template method was about 30 % or even higher than that of conventional samples. This review mainly focuses on the progress of inorganic, organic and biological templates in the preparation of micro- and nano- oxide materials with special morphologies, and the roles of the prepared materials as adsorbents and photocatalysts in dye wastewater treatment. The characteristics and advantages of inorganic, organic and biological template are also summarized. In addition, the applications of template method prepared oxides in the field of sensors, drug carrier, energy materials and other fields are briefly discussed with detailed examples.

Acta Biomater 2020; 101:436-443. [PMID: 31672583 DOI: 10.1016/j.actbio.2019.10.035] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Revised: 10/23/2019] [Accepted: 10/24/2019] [Indexed: 12/16/2022]
Abstract
Protein-templated gold nanoclusters have attracted attention in fluorescence imaging due to their simple synthesis and good biocompatibility. However, limitations still exist such as poor colloid stability and undesirable fluorescence intensity. Here we describe the self-assembly of keratin-templated gold nanoclusters via a simple and mild preparation process, including keratin-templated synthesis of gold nanoclusters (AuNCs@Keratin), silver ions modification of AuNCs@Keratin (AuNCs-Ag@Keratin), and gadolinium ions-induced aggregation of AuNCs-Ag@Keratin (AuNCs-Ag@Keratin-Gd). It was demonstrated that the AuNCs-Ag@Keratin-Gd obtained an enhanced fluorescence intensity (6.5 times that of AuNCs@Keratin), high colloid stability for more than 4 months, and good biocompatibility. Moreover, the AuNCs-Ag@Keratin-Gd holds promise in multifunctional applications such as near-infrared (NIR) fluorescence imaging, magnetic resonance (MR) imaging, and redox-responsive drug delivery, extending the applicability of fluorescent gold nanoclusters, especially in biomedical fields. STATEMENT OF SIGNIFICANCE: Assembly-induced fluorescence enhancement has been rarely reported on as it relates to the protein-templated gold nanoclusters (AuNCs). In this work, self-assembly of protein-templated AuNCs was developed for enhanced fluorescence intensity and multifunctional applications, including bioimaging and responsive drug delivery. A cysteine-rich protein, keratin, was utilized as the template to synthesize AuNCs, which underwent silver ion modification and gadolinium ion-induced aggregation. The silver modification of the keratin-templated AuNCs facilitated the formation of a dense aggregate after gadolinium ion-induced assembly, thus generating an enhanced fluorescence intensity. Such a mechanism was confirmed by fluorescence correlation spectroscopy analysis. We believe that this work will extend the applicability of the fluorescent gold nanoclusters, especially in biomedical fields, and provided an effective approach for the mechanism analysis of the assembly-induced fluorescence enhancement via fluorescence correlation spectroscopy.

Abstract
Chemotherapy, surgery, and radiation are accepted as the preferred treatment modalities against cancer, but in recent years the use of immunotherapeutic approaches has gained prominence as the fourth treatment modality in cancer patients. In this approach, a patient's innate and adaptive immune systems are activated to achieve clearance of occult cancerous cells. In this review, we discuss the preclinical and clinical immunotherapeutic (e.g., immunoadjuvants (in-situ vaccines, oncolytic viruses, CXC antagonists, device activated agents), organic and inorganic nanoparticles, and checkpoint blockade) that are under investigation for cancer therapy and diagnostics. Additionally, the innovations in imaging of immune cells for tracking therapeutic responses and limitations (e.g., toxicity, inefficient immunomodulation, etc.) are described. Existing data suggest that if immune therapy is optimized, it can be a real and potentially paradigm-shifting cancer treatment frontier.

Abstract
Vascular endothelial growth factor (VEGF) is an effective growth and angiogenic cytokine, which stimulates proliferation and survival of endothelial cells, and promotes angiogenesis and vascular permeability. Binding VEGF with heparin could protect it from rapid degradation, subsequently allowing it to be controlled release. Primarily, poly(ε-caprolactone) (PCL) and keratin were coelectrospun, followed by conjugating with heparin and subsequently binding VEGF. The loaded heparin and VEGF on these mats were quantified, respectively. The surface characteristics of mats were investigated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The VEGF delivery results indicated these mats could sustainably release VEGF for 2 weeks. Cell viability assays suggested these mats were valid to accelerate human umbilical vein endothelial cells (HUVECs) proliferation, while inhibit human umbilical arterial smooth muscle cells (HUASMCs) growth under the combined actions of VEGF and heparin. The results tested by blood clotting times (APTT, PT, and TT), hemolysis, and platelet adhesion indicated the mats were blood compatible. To sum up, these biocomposite mats are ideal scaffolds for vascular tissue engineering.

Abstract
In recent years, nanoscience and nanotechnology have brought a great revolution in different areas. In particular, the synthesis of transition metal nanoparticles has been of great relevance for their use in areas such as biomedicine, antimicrobial properties or catalytic applications for chemical synthesis. Recently, an innovative straightforward and very efficient synthesis of these nanoparticles by simply using enzymes as inductors in aqueous media has been described. This represents a very green alternative to the different methodologies described in the literature for metal nanoparticles preparation where harsh conditions are necessary. In this review the most recent advances in the synthesis of metal nanoparticles by this green technology, explaining the synthetic mechanism, the role of the enzyme in the formation of the nanoparticles and the effect on the final properties of these nanoparticles, are summarised. The application of these novel metal nanoparticles-enzyme hybrids in synthetic chemistry as heterogeneous catalysts with metal or dual (enzymatic and metallic) activity and their capacity as environmental and antimicrobial agents have also been discussed.

Abstract
pH/reduction dual-triggered chicken-feather-keratin-based prodrug nanoparticles (C-PK/- SS-Hy-D NPs) were designed via a facile one-pot oxidation coupling reaction between the thiol-functional acid-labile prodrug M-Hy-D and the PEGylated keratin (PK) graft copolymer, for tumor intracellular doxorubicin (DOX) delivery. Due to the encapsulation of the pH and the reduction of the dual-responsive small prodrug D-Hy- SS-Hy-D, a high drug content of 45.8% was obtained in the proposed prodrug nanoparticles. They exhibited excellent pH and reduction of dual-triggered drug release, with cumulative drug release of 88.6% within 51 h in the simulated tumor intracellular microenvironment, while the premature drug leakage was only 13.7% in the simulated normal physiological medium. The in vitro experiments revealed the enhanced antitumor efficacy of the C-PK/- SS-Hy-D NPs than the free DOX at a higher dosage of >10 μg/mL.
