Core-shell inorganic NP@MOF nanostructures for targeted drug delivery and multimodal imaging-guided combination tumor treatment.

It is well known that metal-organic framework (MOF) nanostructures have unique characteristics such as high porosity, large surface areas and adjustable functionalities, so they are ideal candidates for developing drug delivery systems (DDSs) as well as theranostic platforms in cancer treatment. Despite the large number of MOF nanostructures that have been discovered, conventional MOF-derived nanosystems only have a single biofunctional MOF source with poor colloidal stability. Accordingly, developing core-shell MOF nanostructures with good colloidal stability is a useful method for generating efficient drug delivery, multimodal imaging and synergistic therapeutic systems.

Electrochemical aptasensor based on the engineered core-shell MOF nanostructures for the detection of tumor antigens.

It is essential to develop ultrasensitive biosensors for cancer detection and treatment monitoring. In the development of sensing platforms, metal-organic frameworks (MOFs) have received considerable attention as potential porous crystalline nanostructures. Core-shell MOF nanoparticles (NPs) have shown different diversities, complexities, and biological functionalities, as well as significant electrochemical (EC) properties and potential bio-affinity to aptamers.

Nano-bio interaction: An overview on the biochemical binding of DNA to inorganic nanoparticles for the development of anticancer and antibacterial nano-platforms.

It has long been known that inorganic nanoparticles (NPs) can interact with biological macromolecules and show a wider range of biomedical characteristics, including antibacterial, anticancer and antioxidant effects, which cannot be mimicked by their bulky counterparts. It is of great importance in their biomedical applications to study DNA damage in bacterial and cancer cells to develop biocompatible therapeutic nano-platforms derived from inorganic NPs. Therefore, to determine how DNA interacts with inorganic NPs serving as therapeutic agents, thermodynamic and structural studies are essential for an understanding of those mechanisms, thereby allowing for their modulation and manipulation of nano-bio interface.

Copper oxide nanoparticles promote amyloid-β-triggered neurotoxicity through formation of oligomeric species as a prelude to Alzheimer's diseases.

Protein oligomerization is involved in the progression of Alzheimer's disease (AD). In general, a particle that can accelerate protein oligomerization should be considered a toxic material. Several studies reported the progress of nanoparticles (NPs) such as copper oxide (CuO) in biomedical platforms, however, they may have the ability to promote the protein oligomerization process.

Tin oxide nanoparticles trigger the formation of amyloid β oligomers/protofibrils and underlying neurotoxicity as a marker of Alzheimer's diseases.

Alzheimer's disease (AD) is known as one of the most common forms of dementia, and oligomerization of amyloid β (Aβ) peptides can result in the onset of AD. Tin oxide nanoparticles (SnO NPs) showed several applications in biomedical fields can trigger unwanted interaction with proteins and inducing protein aggregation. Herein, we synthesized SnO NPs via the hydrothermal method and characterized by UV-visible, XRD, FTIR, TEM, and DLS techniques.
