Nanoparticles are transforming numerous scientific and industrial sectors. Recently, several notable developments have been reported. Innovative applications are as diverse as they are groundbreaking: nano-spaghetti, solar paint, and treatments for Alzheimer’s disease. These advancements highlight the rapid pace of scientific progress.
Observing the Formation of Metallic Nanoparticles
An international team, led by the Institute of Nuclear Physics of the Polish Academy of Sciences in Krakow, successfully observed the real-time formation of platinum-nickel (PtNi) nanoparticles on an electrode. Using transmission electron microscopy (TEM), researchers decoded the mechanisms of electrodeposition, revealing forming atomic structures. This breakthrough paves the way for designing materials with ultra-precise properties, with potential applications in fuel cells and medicine.
Development of a Molecular Net to Trap Plastic Nanoparticles
As part of the Octo’pousse competition organized by the French Research Institute for Exploitation of the Sea (Ifremer), the Nanotrap project was selected for its innovative approach to combating plastic pollution. The project proposes designing a molecular net capable of physically trapping plastic nanoparticles smaller than one micron. This technology could enhance the detection of nanoplastics in water and, ultimately, contribute to plastic depollution by being integrated into wastewater filtration systems or aquaculture ponds.
Creation of Ultra-Thin Starch Nanofibers Resembling Spaghetti!
Researchers at University College London (UCL) have developed starch nanofibers measuring only 372 nanometers in width. These nanofibers are about 200 times thinner than a human hair. Inspired by pasta-making processes, this technique uses electrospinning to extrude a flour and liquid mixture through an electrically charged needle. These nanofibers hold significant potential in the medical field, particularly in designing wound-healing dressings, bone regeneration scaffolds, and drug delivery systems.
Solar Paint with Nanoparticles Developed by Mercedes-Benz
Mercedes-Benz recently unveiled a groundbreaking innovation: solar paint infused with photovoltaic nanoparticles. This coating, just 5 micrometers thick, can be applied to vehicle body panels, converting sunlight into electricity. According to the manufacturer, a vehicle equipped with this technology could generate enough energy to travel approximately 12,500 miles annually under Los Angeles sunshine, reducing reliance on external energy sources.
Lithium Nanoparticles: A Promising Solution for Alzheimer’s Disease
The French company Medesis Pharma is exploring the potential of nanoparticles in medicine with its experimental treatment, Nanolithium, for Alzheimer’s patients. Encased in nanomicelles, these nanoparticles enable sublingual administration while minimizing lithium toxicity-related side effects. During a Phase IIa clinical study, 66 patients underwent this treatment for 12 months without adverse effects. This approach reduces the lithium dose by 50 times compared to conventional treatments, highlighting the possibilities opened by nanotechnologies for neurodegenerative diseases.
