In the medical field, cerebral ischemia-reperfusion injury is a complex and challenging problem that involves insufficient blood supply to the brain and further damage to brain tissue during subsequent reperfusion processes. Despite scientists constantly seeking new treatment methods, this field still faces many challenges. Nowadays, innovative research conducted by Chongqing Medical University has provided new solutions to this problem.
The research team of Chongqing Medical University leads innovation
The research team of Chongqing Medical University (referred to as Chongqing Medical University) has been committed to the application research of nanotechnology in the medical field. In the treatment of cerebral ischemia-reperfusion injury, they discovered a magical substance called nano-silica. This type of nanoparticle has excellent biocompatibility and stability, providing a new approach for the treatment of cerebral ischemia-reperfusion injury.
The magical effect of silica nano messengers
After in-depth research and experimental verification, the research team of Chongqing Medical University has successfully developed a silica nano messenger. This nano messenger can accurately locate and act on damaged brain tissue in the body, effectively reducing the degree of cerebral ischemia-reperfusion injury through a series of complex biological mechanisms. Specifically, the role of silica nano messengers is manifested in the following aspects:
- Accurate targeting of damaged brain tissue
Through advanced nanotechnology, silica nano messengers can accurately locate damaged brain tissue. During the in vivo transport process, they can recognize and accumulate in the ischemia-reperfusion injury area, providing a targeted basis for subsequent treatment.
- Inhibiting inflammatory response
Cerebral ischemia-reperfusion injury can lead to the occurrence of inflammatory reactions, further exacerbating brain tissue damage. Silicon dioxide nano messengers can inhibit inflammatory responses, alleviate oxidative stress damage to brain cells, and thus protect brain tissue from further damage.
Outlook and Future Outlook
The silica nano messenger created by Chongqing Medical University has brought new hope for the treatment of cerebral ischemia-reperfusion injury. This innovative achievement not only demonstrates the enormous potential of nanotechnology in the medical field but also provides new ideas for solving other complex medical problems. With the deepening of research and continuous improvement of technology, this silica nano messenger can play an essential role in future clinical practice, bringing safer and more effective treatment methods to patients. With the in-depth research and optimization of nano silica materials by researchers, its future in the pharmaceutical field will likely be even brighter.
The application of nano silica powder
One of the significant biomedical applications of nano silica is as a vehicle for drug delivery via eye drops, intravenous injection, oral tablets, or pulmonary inhalation routes.
In textiles, nano silicon can reflect ultraviolet light, resist aging, increase weather resistance, increase strength, and other effects. After testing, it was found that the fiber contains nano silicon that can reflect 75% of 400nm wavelength ultraviolet radiation, and nano silicon below 100nm has antibacterial and deodorizing effects.
In epoxy resin, nanosilicon enhances the properties of acid and alkali resistance, chemical stability, high-temperature resistance, surface hardness, scratch resistance, waterproofing, insulation, etc. Adding less than 20% of nano silicon can double the product’s strength, reducing resin usage and production costs.
In rubber silicone modification: Nano silicon is a product reinforcing agent designed explicitly for rubber silicone modification. Because of pure rubber’s low performance, it is unsuitable for many scenarios and needs to be filled with modified nanosilicon to enhance its reinforcement performance. Controlling the amount of nano silicon used can increase properties such as hardness, temperature resistance, wear resistance, insulation, and dielectric properties.
In coatings: Nano silicon micro powder increases substrate adhesion and film hardness in coatings, paints, primers, and topcoats, preventing surface warping, enhancing corrosion resistance, penetration resistance, self-cleaning, high-temperature resistance, waterproofing, UV resistance, scratch resistance, and other effects. After filling, it can be suspended in the paint film for a long time without affecting transparency, preventing the paint from turning yellow.
Ceramic field: In concrete and refractory materials, silicon micro powder is added to unique refractory materials to form a multi-layer protective layer during oxidation, which has good mechanical properties and high-temperature oxidation resistance. After adding ultrafine silicon powder to special refractory materials, their flowability, sintering ability, bonding ability, and filling porosity performance are all improved to varying degrees, improving structural density and strength, reducing material wear rate, and enhancing corrosion resistance.
