Designer Nanoparticles Destroy a Broad Array of Viruses

Now, an international group of researchers including UIC professor of chemistry Petr Kral, have designed new anti-viral nanoparticles that bind to a range of viruses, including herpes simplex virus, human papillomavirus, respiratory syncytial virus and Dengue and Lentiviruses. Unlike other broad-spectrum antivirals, which simply prevent viruses from infecting cells, the

Gold Nanostars and Immunotherapy Vaccinate Mice Against Cancer

The potent combination also attacked satellite tumors and distant cancerous cells, completely curing two mice and effectively vaccinating one against the disease. The results appeared online in Scientific Reports on August 17. "The ideal cancer treatment is non-invasive, safe and uses multiple approaches," said Tuan Vo-Dinh, the R. Eugene and Susie E. Goodson

Titanium Dioxide Nanoparticles can Exacerbate Colitis

The frequency of inflammatory bowel disease like Crohn's disease and ulcerative colitis has been on the rise in many Western countries for decades. The illnesses are caused by an excessive autoimmune reaction against the intestinal flora. In addition to genetic factors, environmental factors like the Western lifestyle, especially nutrition, play

Switchable Dna Mini-Machines Store Information

The arrays' structures look like accordion-style retractable security gates. Extending or contracting one unit pushes nearby units to change shape as well, working like a domino cascade whose tiles are connected. The arrays' units get their stability from the energy gained when DNA double helices stack up. To be stable, the
