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.
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.
Researchers from The Johns Hopkins University and Northwestern University have discovered how to control the shape of nanoparticles that move DNA through the body and have shown that the shapes of these carriers may make a big difference in how well they work in treating cancer and other diseases.
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.
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.
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.
Experimental work on nanocrystals under pressure has been limited by technical hurdles. But new capabilities using a technique called radial diamond anvil cell x-ray diffraction has opened the door to moving beyond computer modeling and into the lab.
A research group at the National Institute of Standards and Technology (NIST) has developed a relatively simple, fast and effective method of depositing uniform, ultrathin layers of platinum atoms on a surface.
A VCU research team, led by Everett Carpenter Ph.D., associate professor of inorganic and materials chemistry and affiliate professor of chemical and life science engineering in the VCU College of Humanities and Sciences, has been selected to participate in the inaugural I-Corp at ARPA-E program to help academic scientists expand their focus in ways to transition technology from basic research to commercial applications.
Physiker aus Augsburg und Loughborough berichten in den Physical Review Letters über neue Erkenntnisse zum Verhalten und zu den Steuerungsmöglichkeiten von Ladungsträgern in einatomaren Kohlenstoffschichten.
