The structure of individual molecules and their properties, such as chirality, are difficult to monitor in real time. It turns out that temporarily bridging molecules together can provide a lens into their dynamics. Scientists now have exposed new pathways for investigating biochemical reactions at the nanoscale. They found that optoplasmonic coupling allows for the detection of biomolecules that approach nanoparticles, while they attach, detach, and interact in a variety of ways. The technique paves the way for many future single-molecule analysis techniques that researchers have only been dreaming about.
Engineering researchers have created mesh-like mats made with tannic acid; used in bandages or inside food storage containers, they can help promote prolonged antioxidant activity.
Several therapeutic gases are quite helpful for treatment of many inflammation-related diseases including cancer, but also exhibit some shortcomings such as limited therapy efficacy. Gas nanomedicine appears as an emerging cutting edge of nanomaterials and gas medicine, raising urgent demand on nanomaterials to address the issues of gas medicine.
The devices could be used in new, safe imaging technology with far higher resolution than current ultrasound devices used to detect small tumours.
Quantum technology was once considered to be something very expensive and available only to the largest research centers. However, in our days it is widely used in many applications, and one of them is magnetic resonance imaging.
Chemists have developed sponges to capture various target substances, like gold, mercury and lead, dissolved in solution. The sponges are actually porous crystals called metal organic frameworks, and now one exists for capturing toxic hexavalent chromium from water.
Researchers propose the smart protection mechanism of responsive single walled carbon nanotube membranes against environmental threats.
A drug-loaded microrobotic needle effectively targets and remains attached to cancerous tissue in lab experiments without needing continuous application of a magnetic field, allowing more precise drug delivery.
Wavy silver nanowire network on stretchable substrate were fabricated for large-scale stretchable and transparent electrodes.
