For anticancer vaccination, antigenic material can be collected directly from a patient's resected tumor, formulated into a biomimetic nanoparticle, and then administered back into the patient to promote tumor-specific immunity. For antibacterial vaccination, strain-specific virulence factors or membrane can be immobilized onto nanoparticle substrates, and the resulting complexes can be used to vaccinate patients with an identified risk against the associated pathogen. • Email to a friend • Drops of water falling on or sliding over surfaces may leave behind traces of electrical charge, causing the drops to charge themselves. Scientists have now begun a detailed investigation into this phenomenon that accompanies us in every-day life. • Email to a friend • Researchers have developed a tiny unit with perovskite diodes that is both an optical transmitter and a receiver. This is highly significant for the miniaturisation of optoelectronic systems. • Email to a friend • Researchers have invented a machine-learning based algorithm for quantitatively characterizing, in three dimensions, materials with features as small as nanometers. • Email to a friend • Turning a brittle oxide into a flexible membrane and stretching it on a tiny apparatus flipped it from a conducting to an insulating state and changed its magnetic properties. • Email to a friend • Biochemists have created 'smart' proteins that function inside human cells by turning genes on and off. • Email to a friend • Noble metal aerogels are widely investigated for electrocatalysis applications due to their large specific surface areas and the high catalytic activity of noble metals. However, their fabrication methods are cumbersome. Now though, researchers have developed a freeze-thaw method capable of preparing various hierarchically structured noble metal gels within only one day directly from dilute solutions without extra additives. The method fits various noble metals, and multi-scale structures can be obtained across nanometer and micrometer scales. • Email to a friend • |
