Injectable nanoengineered bandage targets fatal internal bleeding
Self-administered hydrogel designed to stem fatal blood loss, activate wound healing process.
Nanovalves for nanoparticles
Newly-developed nanovalves allow the flow of individual nanoparticles in liquids to be controlled in tiny channels. This is of interest for lab-on-a-chip applications such as in materials science and biomedicine.
One-way roads for spin currents
Researchers have shown a completely new approach to controlling spin currents based on strong spin-spin interactions, which results in diodes for spin current with a giant rectification.
Nanotechnology food packaging releases preservatives on demand
Researchers demonstrate fruit preservative delivery from a nanocomposite packing in response to the signal from the fruit stimuli.
Quantum dot technique can track drug and gene delivery to cells
The new tracking technique uses single-molecule imaging, which allows to observe individual molecules over time, and quantum dots, which act like tiny beacons inside cells.
Leveraging imperfections to create better-behaved quantum dots
Potentially paving the way toward advanced computers, lasers or optical devices, researchers have revealed new effects in tiny electronic devices called quantum dots.
