It is a more efficient drug delivery system that includes the development of nano-particulate system and its superiority over the conventional drug delivery system. Among all available nanoparticles, NLC has gained more attention due to its superior characteristics such as lipophilic, biodegradable and biocompatible. This lipid nanoparticulate system is more advantageous over liposomes, microparticles, emulsions and solid lipid nanoparticles. NLCs have emerged as a promising carrier for the delivery of targeted drug substances via oral, parenteral, topical, pulmonary, transdermal and ocular routes. These nanocarriers are utilized for the delivery of both lipophilic as well as hydrophilic drugs. NLCs are composed of a matrix of physiological lipids i.e. solid lipid and liquid lipid, emulsifiers and water. NLCs provide an opportunity for large scale production, ease of preparation with enhanced encapsulation, targeted efficiency and reduced toxic effects. This review is focused on the advantages, limitations, methods of preparation, characterization and applications of NLCs.\u0000","PeriodicalId":10924,"journal":{"name":"Current Nanomaterials","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45225582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New solutions for cancer therapy can overcome the shortcomings and problems of conventional therapies by designing drug delivery nanosystems.\u0000\u0000\u0000\u0000Methods: In this study, magnetic Fe3O4@AU@Albumin core-shell-shell (CSS) nanoparticles were synthesized and characterized by various analyses such as transmission electron microscopy (TEM), X-ray diffraction (XRD) and vibrating sample magnetization (VSM). Podophyllotoxin (PPT) was then loaded on magnetic nanoparticles as an anti-cancer drug and its effect on HT-29 and MCF-7 cell lines was evaluated using MTT assay.\u0000\u0000\u0000\u0000Result: The crystallinity of synthesized Fe3O4 magnetic nanoparticles was confirmed by XRD analysis. Next, a layer of gold was coated the Fe3O4 MNPs. The UV-Vis analysis of core-shell nanoparticles (iron oxide/gold)confirm the successful synthesis of these nanoparticles. The surface of the core-shell nanoparticles was then coated with albumin to load the drug. TEM image confirmed the existence of albumin nanoparticles loaded with core-shell magnetic nanoparticles. \u0000VSM analysis revealed that iron oxide, Fe3O4@AU, and Fe3O4@AU@Albumin nanoparticles have the highest magnetic properties, respectively. After synthesis of PPT loaded into MNP, the loading efficiency was 50%. The IC50 values of PPT alone and loaded into nanoparticles on MCF-7 cells after 24 hours were 3085.75 and 1868.09 nM, respectively, which were significantly toxic (P-value≤0.05) but not significant after 48 hours. The cytotoxicity of PPT loaded on nanoparticles was significantly more toxic to HT-29 cells after 24 and 48 h than PPT alone (P-value≤0.05).\u0000\u0000\u0000\u0000Conclusion: The anticancer drug of PPT-loaded MNPs has significant advantages over PPT alone due to its improved properties with appropriate cytotoxic activity.

Curcumin is a polyphenol identified as the main active ingredient in turmeric and has been used in the treatment of various diseases and ailments. Additionally, the pharmacological activities of curcumin on many cancers have been investigated substantially due to its ability to regulate many signaling pathways involved in cancer tumorigenesis and metastasis. However, the low solubility and bioavailability of curcumin limit its benefits, urging the need for new curcumin formulations and delivery systems. Nanotechnology has been widely publicized in cancer treatment not only to overcome the limitations of poorly soluble and physiologically unstable compounds but also to improve the delivery of the drug to the diseased site and cellular uptake. In this review, we summarized the main anti-tumor effect of curcumin and its mode of action on breast cancer and focused on the anticancer efficacy of various and recent curcumin nanoformulations and delivery systems. Such nanotechnological systems could pave the way to address a new future direction in this research area, enhancing the therapeutic potential of curcumin in the treatment of breast cancer.
