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
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
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 […]
A career in cancer
Dr Bruce Zetter is the Charles Nowiszewski Professor of Cancer Biology at Harvard Medical School. He is known internationally as an expert on cancer biology, diagnosis and treatment. He currently works to find treatments for highly aggressive, metastatic cancers and also serves as an advocate for young scientists and for improved relationships between academia and industry. Dr Bruce Zetter started […]
