Scientists overcome nanotech hurdle

When you make a new material on a nano scale how can you see what you have made? A team of scientists has made a significant step toward overcoming this major challenge faced by nanotechnology scientists.

With new research published today (13 August) in ChemBioChem, the team from the University of Liverpool, The School of Pharmacy (University of London) and the University of Leeds, show that they have developed a technique to examine tiny protein molecules called peptides on the surface of a gold nanoparticle. This is the first time scientists have been able to build a detailed picture of self-assembled peptides on a nanoparticle and it offers the promise of new ways to design and manufacture novel materials on the tiniest scale – one of the key aims of nanoscience.

New disease-fighting nanoparticles look like miniature pastries

Ultra-miniature bialy-shaped particles — called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City — could soon be carrying medicinal compounds through patients’ bloodstreams to tumors or atherosclerotic plaques.
