Synchronized nanoscale oscillators may spur new devices

Synchronization phenomena are everywhere in the physical world - from circadian rhythms to side-by-side pendulum clocks coupled mechanically through vibrations in the wall. Researchers have now demonstrated synchronization at the nanoscale, using only light, not mechanics.

Physicists make strides in understanding quantum entanglement

Using computers to calculate the extreme version of quantum entanglement - how the spin of every electron in certain electronic materials could be entangled with another electron's spin - the research team found a way to predict this characteristic. Future applications of the research are expected to benefit fields such as information technology.

Nanochains mark micrometastases for early diagnosis, treatment

Malignant cells that leave a primary tumor, travel the bloodstream, and grow out of control in new locations cause the vast majority of cancer deaths. A new type of nanoparticle construct, developed at Case Western Reserve University, detects these metastases in mouse models of breast cancer far earlier than current methods, which is a step toward earlier detection and treatment.

Researchers create unique photoluminescent nanoparticles

An international research team has created unique photoluminescent nanoparticles that shine clearly through more than three centimeters, or more than an inch, of biological tissue, a depth that makes them a promising tool for deep-tissue optical bioimaging.

First-of-its-kind self-assembled nanoparticle for targeted and triggered thermo-chemotherapy

Researchers have succeeded in designing and demonstrating the effectiveness of a first-of-its-kind, self assembled, multi-functional, near-infrared (NIR) responsive gold nanorods that can deliver a chemotherapy drug specifically targeted to cancer cells and selectively release the drug in response to an external beam of light while creating heat for synergistic thermo-chemo mediated anti-tumor efficacy.

Gold nanorods detect ovarian cancer, improve surgical removal in mice

Using gold nanorods that are visible using two different types of imaging techniques, researchers at the Stanford University Center for Cancer Nanotechnology Excellence and Translation (Stanford CCNE-T) have developed a promising new method that may be able to detect early stage ovarian cancer and help surgeons completely remove the detected tumor.

Multimode waveguides bring light around corners for compact photonic chips

Light is sometimes uncooperative. Among other things, it doesn't like to go around tight corners. Cornell and Massachusetts Institute of Technology researchers have a solution that could offer increased bandwidth for fiber-optic communication, both in long-haul transmission and in the dense traffic in large data centers.
