Osteoarthritis (OA) is a prevalent disease characterized by subchondral bone fracture, and there is no accurate and specific treatment yet available. Recently, the research team has synthesized a new multifunctional scaffold that can potentially solve this problem. Using photo-polymerized modified hyaluronic acid (GMHA) as a substrate and hollow porous magnetic microspheres (HAp-Fe3O4) as the base, they designed a scaffold with optimum properties for subchondral bone repair.
The accurate diagnosis and treatment of acute ischemic stroke (AIS) require high sensitivity and resolution imaging technologies. Unfortunately, such technologies are still lacking in the field. However, on July 4th, 2024, Small reported the development of a Contrast-Enhanced Susceptibility-Weighted Imaging (CE-SWI) technique that is capable of meeting high-precision imaging needs. The technique employs Fe3O4 nanoparticles modified by Dextran (Fe3O4@Dextran NPs), which allows for high sensitivity and resolution imaging of AIS at 9.4T.
The combination of flexibility and elasticity makes elastic materials essential in a wide range of industries, including automotive, construction, and consumer goods. Moreover, they are increasingly attractive in emerging fields such as microfluidics, soft robotics, wearables, and medical devices. However, having sufficient mechanical strength is a prerequisite for any application. Thus, solving the seemingly contradictory attributes between softness and strength has always been an eternal pursuit.
Silver nanoparticles (AgNPs) have been extensively used as a potent reagent to enhance the Raman scattering of surface-enhanced Raman spectroscopy (SERS) due to their excellent stability and enhancing properties. In a recent publication by Nano Convergence, a more eco-friendly and efficient method of in-situ manufacturing of SERS substrates with AgNPs has been reported.
The use of silver-based materials for their strong antibacterial properties has long been recognized, but concerns about their potential toxicity have led to the need for alternative, safe, and effective antibacterial systems. Against this backdrop, a team of researchers has developed a novel synergistic antibacterial system using arginine-modified chitosan (ACS) composite silver-loaded MMT (AgNPs@MMT) for food preservation. This article explores this promising solution in detail.
The fusion of nanotechnology and textile engineering has led to the development and improved performance of multifunctional smart materials in various application fields. One recent breakthrough is the one-step synthesis of AgNPs/CNTs spray-coating solution, which is used to anchor silver nanoparticles on multi-walled carbon nanotubes and apply them onto nonwoven fabric to create multifunctional smart textiles.
