The researchers working at Rice University have developed a complex polyurethane nanomaterial that may stop bullets on their way. The researchers claim that, while the material might not be able to withstand bigger bullets, 9mm-sized bullets can easily be blocked by the material and could have their entryway sealed behind it, before they could completely enter.
While conducting tests, the researchers could shoot tiny glass beads into the material, which successfully prevented the beads from entering their tracks. The team of researchers from MIT was initially searching for ways to create materials “more resistant to failure or deformation” and more bulletproof than is available today. Materials provide.
The outcome, as researchers claim, will be more durable and stronger armor for police officers and soldiers in addition to an improved bulletproof glass that can be used in armored vehicles. The brand new polyurethane material melts it into a liquid that will stop a bullet and fill in the holes the bullet created.
In essence, any bullet that strikes the material will result in no shattering or breaking so should this material be made in glass impact; bullets won’t break and crack it. However, the material instead be melted around the shot, causing just a slight deformation in the glass. The work and research on the brand new material are still in the initial stages, and there are no details regarding the date or time we can expect the material to be adopted by the mainstream.
Polyurethane nanoparticles, a new tool for biomedical applications?
The development of biocompatible, precise, and efficient nanostructured systems remains an issue in the biomedical field. Polymeric nanoparticles are potential platforms for delivering drugs, medical imaging, and simultaneous diagnosis and delivery. Polyurethanes are attracting increasing attention because of their polymerization versatility, excellent mechanical properties, and high biocompatibility. In this article, we will review the most common synthetic techniques used to produce nanoparticles with a particular focus on the polymerization process in nano-emulsion media and their application as delivery systems for drugs and diagnostic and theranostic tools specifically for the treatment of cancer. Although significant advancements have been made, polyurethane nanoparticles will have to overcome the limitations currently in biomedical research, such as drug solubilization, targeted specificity therapeutic dosage, biosafety profiles, and the capability to overcome biological barriers, and their effectiveness when taken orally.
