Iron oxide nanoparticles are extensively studied for their use in medical applications due to their unique magnetic properties. However, one of the major concerns with the use of inorganic nanoparticles is their potential biotoxicity. Inorganic nanoparticles have a slow clearance kinetics that can pose a potential threat to their in vivo application. The clearance of nanoparticles from the body largely depends on the surface physicochemical properties rather than their size and shape.

Antibiotics refer to drugs that can inhibit bacterial growth, damage their living environment, and effectively and continuously exert their effects. Antibacterial agents are divided into two categories: organic antibacterial agents and inorganic antibacterial agents. Among them, organic antibacterial agents include natural and synthetic types, while inorganic antibacterial agents mainly include metals, metal ions, and oxides. The commonly referred to antibacterial measures include inhibition, killing, elimination of toxins secreted by bacteria, and prevention. Due to the strong thermal stability, long-lasting functionality, and safety and reliability of inorganic antibacterial agents, coupled with the development of ultra-fine technology in recent years, nanoscale inorganic antibacterial agents can be mass-produced and blended or composite into chemical fibers, ensuring the industrialization of antibacterial chemical fibers.

A recent study utilizing mesoporous silica nanoparticles (MSN) loaded with trehalose dimycolate (TDM) has shown promise in enhancing the anti-tumor effects of combining the nanoparticles with the WRN nuclease. The research was recently published in Advanced Science on August 29, 2024.

Osteoarthritis (OA) is a common degenerative joint disease that results in severe pain, impaired mobility, and even disability. An increasing body of evidence suggests that improving the dysbiosis of gut microbiota and increasing the content of short-chain fatty acids (SCFAs) can further alleviate clinical symptoms and delay the progression of this disease.

the development of Van der Waals welding for carbon nanotubes represents a significant advancement towards harnessing the exceptional mechanical properties of CNTs on a macroscopic scale. With further refinement and optimization, this innovative welding method has the potential to revolutionize the manufacturing of high-performance materials, driving progress in fields requiring lightweight, durable, and strong structural components. As researchers continue to push the boundaries of nanotechnology, the future looks promising for the widespread adoption of carbon nanotubes in industrial applications.

Colloidal gold refers to a colloidal system formed by suspending nanoscale gold particles in an appropriate solution. The size of gold particles typically ranges from 1 to 100 nanometers.
