What can peptide-coated nanoparticles tell us about the causes of dementia?

Kazushige Yokoyama, Professor of Chemistry at the State University of New York Geneseo College, investigates how peptides interact. Along with Akane Ichiki, an undergraduate student at the institution, his team have been investigating the peptides involved in fibrillogenesis, the process which occurs in the brain to form aggregates responsible for some of the symptoms involved in neurodegenerative diseases like Alzheimer’s […]

Nanotechnology provides new methods for oral delivery of peptides

Nanotechnology provides new methods for oral delivery of peptides

One aspect of successful drug development is efficient delivery to affected organs. Most drugs are taken by mouth, travel to the intestines, are absorbed into the bloodstream, and circulated to organs of interest. However, a class of potent drugs known as peptides cannot withstand this abrasive route and are directly injected into veins, under the skin, or into muscles. Injections […]

Probing surface morphology with virtual plasmonic dimers

Probing surface morphology with virtual plasmonic dimers

Nanoparticles exhibit electronic and optical properties that may significantly differ from those of bulk materials or small molecules. By exploiting the optical generation of plasmon dimers of nanoparticles in the vicinity of semiconducting surfaces, Dr Ingo Barke from the University of Rostock, Germany and his collaborators are proposing a new class of ultrasensitive sensors to probe the morphology of surfaces […]

Laser ablation in liquid: A powerful route to new nanoparticle catalysts

Dr Katharine Tibbetts (Virginia Commonwealth University) has been developing a novel approach for the synthesis of metal nanoparticles, based on a reactive laser ablation in liquid technique. She uses ultra-short laser pulses to ionise water molecules and generate a highly energetic plasma of electrons capable of reducing soluble metal ions to neutral atoms, which then coalesce to generate a nanoparticle […]

Designing catalysts bit by bit

Prof Johnston and Dr Baletto use computational techniques to design and tailor nanomaterials, focusing on nanoalloys and their catalytic properties.

Catalysis, using reagents to speed up chemical reactions, is big business. From synthesising new chemicals to cleaning up the exhaust fumes from cars and sustainable energy devices such as hydrogen fuel cells, catalysts play a huge role in our daily lives. Prof Roy L. Johnston and Dr Francesca Baletto at the University of Birmingham and King’s College London respectively are using novel computational approaches […]
