To accomplish effective cancer imaging and integrated therapy, the multifunctional nanotheranostic FeO-MTX@HBc core-shell nanoparticles (NPs) were designed. A straightforward method was demonstrated for efficient encapsulation of magnetic NPs into the engineered virus-like particles (VLPs) through the affinity of histidine tags for the methotrexate (MTX)-Ni chelate. HBc-His VLPs shell could protect FeO-MTX NPs from the recognition by the reticuloendothelial system as well as could increase their cellular uptake efficiency. Through our well-designed tactic, the photothermal efficiency of FeO NPs were obviously improved and upon near-infrared (NIR) laser irradiation. Moreover, Magnetic resonance imaging (MRI) results showed that the FeO-MTX@HBc core-shell NPs were reliable T-type MRI contrast agents for tumor imaging. Hence the FeO-MTX@HBc core-shell NPs may act as a promising theranostic platform for multimodal cancer treatment.

As an essential B vitamin, folate participates in one‑carbon metabolism. The 5-methyltetrahydrofolate (5-MTHF) avoids the drawbacks associated with folic acid and native folylpolyglutamate folate in food, thereby emerging as a superior alternative to folate supplement. To enhance the stability and digestibility of 5-MTHF, nanoliposome (NL) was modified using a layer-by-layer self-assembly method with chitosan (CH) and pectin (P).

Biomimetic calcification is a micro-crystallization process that mimics the natural biomineralization process, where biomacromolecules regulate the formation of inorganic minerals. In this study, it is presented that a protein-assisted biomimetic calcification method for the in situ synthesis of nitrogen-doped metal-organic framework (MOF) materials. A series of unique core-shell structures are created by utilizing proteins as templates and guiding agents in the nucleation step, creating ideal conditions for shell growth.

Covalent organic frameworks (COFs), known for their exceptional in situ encapsulation and precise release capabilities, are emerging as pioneering drug delivery systems. This study introduces a hypoxia-responsive COF designed to encapsulate the chemotherapy drug gambogic acid (GA) in situ. Bimetallic gold-palladium islands were grown on UiO-66-NH (UiO) to form UiO@Au-Pd (UAPi), which were encapsulated with GA through COF membrane formation, resulting in a core-shell structure (UAPiGC).

Construction of core-shell structured electrocatalysts with a thin noble metal shell is an effective strategy for lowering the usage of the noble metal and improving electrocatalytic properties because of the structure-induced geometric and electronic effects. Here, the synthesis of a novel core-shell structured nanocatalyst consisting of a thin amorphous Pd shell and a crystalline PdCu core and its significantly improved electrocatalytic properties for both formic acid oxidation and oxygen reduction reactions are shown. The electrocatalyst exhibits 4.

Due to the high mortality rate of ovarian cancer, there is a need to find novel strategies to improve current treatment modalities. Natural compounds offer great potential in this field but also require the careful design of systems for their delivery to cancer cells. Our study explored the anticancer effects of novel resveratrol (RSV)- and curcumin (CUR)-loaded core-shell nanoparticles in human ovarian cancer cells.
