The U.S. Food and Drug Administration has issued a final guidance for industry, 'Use of Nanomaterials in Food for Animals', which is intended to assist industry and other stakeholders in identifying potential issues related to safety or regulatory status of food for animals containing nanomaterials or otherwise involving the application of nanotechnology.
A miniaturized sensor based on Raman spectroscopy that can quickly and accurately detect or diagnose substances at a molecular level. The system can do chemistry, biology, biochemistry, molecular biology, clinical diagnosis, and chemical analysis,
Scientists discuss a new way to apply a widely used local-structure analysis tool - known as atomic pair distribution function (PDF) analysis - to x-ray scattering data from thin films, quickly yielding high-quality information on the films' atomic structure. The work creates new avenues for studies of nanocrystalline thin films.
Scientists have developed a technique that prompts microparticles to form ordered structures in a variety of materials. The advance offers a method to potentially improve the makeup and color of optical materials used in computer screens along with other consumer products.
