A new technology developed at MIT may help to make biomarker detection much easier. The researchers, led by Sangeeta Bhatia, have developed nanoparticles that can home to a tumor and interact with cancer proteins to produce thousands of biomarkers, which can then be easily detected in the patient's urine.
Wissenschaftler des Helmholtz-Zentrums Dresden-Rossendorf haben herausgefunden, dass Gold stark magnetisch werden kann - wenn die Partikel klein genug und die richtigen Reaktionspartner vorhanden sind.
Professor Sargent, who is also the Vice-Dean, Research, of the Faculty of Applied Science & Engineering, is widely known as the inventor of full-spectrum solution-processed solar cells, a new class of solar energy harvesting devices based on colloidal quantum dots.
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.
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.
Using common laboratory filter paper coated with antibody-labeled gold nanorods, a team of investigators at Washington University in St. Louis has developed a rapid and inexpensive method for detecting biomarkers of kidney cancer in urine.
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.
