NIST Reference Materials Are 'Gold Standard' for Bio-Nanotech Research

The National Institute of Standards and Technology (NIST) has issued its first reference standards for nanoscale particles targeted for the biomedical research community—literally “gold standards” for labs studying the biological effects of nanoparticles. The three new materials, gold spheres nominally 10, 30 and 60 nm in diameter, were developed in cooperation with the National Cancer Institute’s Nanotechnology Characterization Laboratory (NCL).

Biodegradable Nanoballs for Drug Delivery

Dutch researcher Cristianne Rijcken has developed a new type of biodegradable nanoparticle. The spherical structures can encapsulate various fat-soluble medicines, which makes it easier to target tumour tissue. These nanoballs are highly promising carriers for the controlled release of anticancer drugs. Rijcken recently gained her doctorate for this research from Utrecht University.

Self-Organising Nanoparticles: A Model for Tomorrow’s Nanofactories

With inspiration from bacteria and butterflies, researchers at Stockholm University have developed a new method that shows how nanomaterials can be produced in the future. In an article in Proceedings of the National Academy of Sciences, Professor Lennart Bergström shows how a glass bottle and a simple hobby magnet can be used to produce and arrange extremely small cubes of iron oxide in a perfectly checkered pattern.

Scientists Train Nano-“Building Blocks” to Take on New Shapes

ImageResearchers from the University of Delaware and Washington University in St Louis have figured out how to train synthetic polymer molecules to self-assemble and form into long, multicompartment cylinders 1000 times thinner than a human hair, with potential uses in radiology, signal communication and the delivery of therapeutic drugs in the human body.
