Hybrid Nanoparticles of Citrate-Coated Manganese Ferrite and Gold Nanorods in Magneto-Optical Imaging and Thermal Therapy

Saeideh Arsalani et al.

Summary: The development of nanomaterials has attracted attention in the field of nanomedicine for advancing cancer diagnosis and treatment over the past few decades. Gold nanorods and magnetic nanoparticles are commonly used nanostructures in biomedical applications due to their attractive optical properties and superparamagnetic behaviors, respectively. In this study, a simple combination of plasmonic and superparamagnetic properties was proposed by synthesizing hybrid nanoparticles of citrate-coated manganese ferrite and cetyltrimethylammonium bromide-coated gold nanorods.

Hybrid nanostructures based on gold nanoparticles and functional coordination polymers: Chemistry, physics and applications in biomedicine, catalysis and magnetism

Roger Sanchis-Gual et al.

Summary: In the past decade, hybrid nanomaterials, specifically those consisting of gold nanoparticles combined with coordination polymers, have attracted interest in the scientific community. These materials offer advantages over traditional inorganic nanomaterials and organic compounds, such as versatile chemistry, easy processing, large surface area, low toxicity, biodegradability, and electronic/magnetic functionalities. Integrating gold nanoparticles with coordination polymers in various nanostructures has expanded their properties and applications, overcoming limitations of gold nanoparticles for certain uses. This review focuses on different hybrid nanostructures that combine colloidal gold nanoparticles with coordination polymers, exhibiting physical (e.g. ferromagnetism, photomagnetism, spin switching) or chemical (e.g. electrocatalysis) properties of interest. The enhanced properties and synergistic effects resulting from this combination are thoroughly discussed. These hybrid materials show promise for various applications, particularly in biomedicine, catalysis, magnetism, and sensing.

Unraveling a role of molecular linker in nanoparticles self-organization by SERS spectroscopy: Comparative study of three aromatic diamines

Elena V. Solovyeva et al.

Summary: In this study, the effect of linker rigidity and conjugation degree on the morphology and optical properties of aggregates formed by silver nanoparticles (NPs) was systematically investigated. The concentration profiles obtained for effective NP linking were found to be non-monotonic. Transmission electron microscopy and absorption spectroscopy revealed that stilbene and tolane compounds effectively linked the silver NPs, forming quasi-spherical aggregates and elongated dimers/trimers, while bibenzyl compound exhibited surface-initiated azo conversion instead of NPs bridging. It was observed that the degree of NP aggregation decreased with increasing aromaticity and springiness of the linker molecule. The ability of rigid diamines to assemble nanoparticles with a finite degree of aggregation, even at high concentrations, distinguishes them advantageously from aliphatic bifunctional linkers. Highly stable plasmonic aggregates suitable for nano- and meta-materials and imaging applications can be obtained using this method.

Simply and effectively control the shell thickness of hollow mesoporous silica nanoparticles by polyethylene glycol for drug delivery applications

Ngoc Hoi Nguyen et al.

Summary: This study demonstrates the use of polyethylene glycol (PEG) as a capping agent to control the mesoporous shell thickness of hollow mesoporous silica nanoparticles (HMSN). Increasing the molecular weight or concentration of PEG leads to an increase in the mesoporous shell thickness. The samples synthesized with PEG exhibit higher surface area and better sustained release profile for drug delivery applications.

Oligonucleotide-Functionalized Gold Nanoparticles for Synchronous Telomerase Inhibition, Radiosensitization, and Delivery of Theranostic Radionuclides

Bas M. Bavelaar et al.

Summary: In this study, gold nanoparticles (AuNPs) were used to enhance cellular uptake of oligonucleotides targeting telomerase. The addition of Tat to AuNPs increased nuclear localization and induced DNA double-strand breaks in telomerase-positive cells. In-111-Match-AuNP-Tat shows promise as a vector for delivering radionuclides to cancer cells while sensitizing them to the effects of emitted radiation.
