Incorporating silver nanoshell-coated mesoporous silica nanoparticles improves physicochemical and antimicrobial properties of chitosan films.

Tailoring nanomaterials with tunable properties is of great importance to develop multifunctional candidates in the biomedical field. In the present study, we aimed to develop a promising nano-hybrid system composed of chitosan (CS) and mesoporous silica nanoparticles with a silver nanoshell coat (CS-AgMSNs). The physicochemical properties of CS-AgMSNs films were characterized using various techniques.

Alginate-coated caseinate nanoparticles for doxorubicin delivery: Preparation, characterisation, and in vivo assessment.

Natural protein-based nanoparticles are promising nano-vehicles for the delivery of chemotherapeutic drugs. Caseinate nanoparticles loaded with doxorubicin (CasNPs-DOX) have been surface-modified with the natural polysaccharide alginate to generate the novel nanocarrier Alg-CasNPs-DOX. The fabricated nanoparticles have been characterised by transmission electron microscopy, Fourier-transform infrared spectroscopy, dynamic light scattering, fluorescence spectroscopy, and zeta potential measurement.

Long-term biodistribution and toxicity of curcumin capped iron oxide nanoparticles after single-dose administration in mice.

Aim: In this study, in vivo biodistribution, clearness and toxicity of curcumin capped iron oxide nanoparticles (Cur-IONPs) were addressed in different body organs.

Materials And Methods: The physicochemical properties of the prepared Cur-IONPs were investigated. Long term (3 weeks) biodistribution, clearness and toxicity were assessed for a single-dose administration of Cur-IONPs (5 mg/kg).

Multifunctional Chitosan-Capped Gold Nanoparticles for enhanced cancer chemo-radiotherapy: An invitro study.

Over the last decade, chemo-radiotherapy represented a well-established paradigm for cancer treatment. Developing new strategies to promote the therapeutic efficacy while reducing toxic side effects of chemo-radiotherapy is a main research objective in cancer therapy. A promising new oncological strategy for enhancing chemo-radiotherapy against cancer involves the utilization of multifunctional nanoparticles (nanocarriers and radiosensitizers).

Doxorubicin loaded magnetic gold nanoparticles for in vivo targeted drug delivery.

Treatment of approximately 50% of human cancers includes the use of chemotherapy. The major problem associated with chemotherapy is the inability to deliver pharmaceuticals to specific site of the body without inducing normal tissue toxicity. Latterly, magnetic targeted drug delivery (MTD) has been used to improve the therapeutic performance of the chemotherapeutic agents and reduce the severe side effects associated with the conventional chemotherapy for malignant tumors.

Ehrlich tumor inhibition using doxorubicin containing liposomes.

Ehrlich tumors were grown in female balb mice by subcutaneous injection of Ehrlich ascites carcinoma cells. Mice bearing Ehrlich tumor were injected with saline, DOX in solution or DOX encapsulated within liposomes prepared from DMPC/CHOL/DPPG/PEG-PE (100:100:60:4) in molar ratio. Cytotoxicity assay showed that the IC50 of liposomes containing DOX was greater than that DOX only.

Preparation and characterization of magnetic gold nanoparticles to be used as doxorubicin nanocarriers.

Magnetic targeted drug delivery (MTD), using magnetic gold nanoparticles (Fe3O4@Au NPs) conjugated with an anti-cancer drug is a promise modality for cancer treatment. In this study, Fe3O4@Au NPs were prepared and functionalized with thiol-terminated polyethylene glycol (PEG), then loaded with anti-cancer drug doxorubicin (DOX). The physical properties of the prepared NPs were characterized using different techniques.
