Microfabrication breakthrough could set piezoelectric material applications in motion

Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, University of Wisconsin-Madison engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.

New device uses gold nanoparticles to test for lung cancer

The metabolism of lung cancer patients is different than the metabolism of healthy people. And so the molecules that make up cancer patients' exhaled breath are different too. A new device pioneered at the University of Colorado Cancer Center and Nobel-Prize-winning Technion University in Haifa, Israel uses gold nanoparticles to trap and define these molecules in exhaled breath.

CRANN launches educational package to introduce nanoscience to Irish scool science classrooms

Today, during Science Week, CRANN, the SFI-funded nanoscience institute based in Trinity College Dublin, has announced the launch of an innovative educational package, 'Nano in My Life'. The package will introduce Transition Year and Senior Cycle students to nanoscience, the study of materials at very tiny dimensions, which is set to become part of the proposed new Leaving Certificate syllabi.

Nanoparticles harvest invisible cancer biomarkers

Cancer biologists have long presumed that tumor cells shed telltale markers into the blood and that finding these blood-borne biomarkers could provide an early indicator that cancer is developing somewhere in the body. Now, a research team at the George Mason University has shown that they can fish out the "invisible" proteins masked by albumin and other high concentration proteins using porous nanoparticles decorated with a series of chemical baits, each designed to harvest specific types of trace proteins from body fluids.

Biologically targeted nanoparticles may boost radiation therapy effects

Making a tumor more sensitive to radiotherapy is a primary goal of combining chemo and radiation therapy to treat many types of cancer, but with the chemotherapy drugs come unwanted side effects. Now, investigators from the University of North Carolina report what they believe is the first pre-clinical demonstration of the potential of molecularly targeted nanoparticles as a promising new class of agents that can improve chemoradiotherapy treatment.

Nanoparticles seek and destroy drug-resistant glioblastoma

Scientists developed a method to combine a tumor-homing peptide, a cell-killing peptide, and a nanoparticle that both enhances tumor cell death and allows the researchers to image the tumors. When used to treat mice with glioblastoma, this new nanosystem eradicated most tumors in one model and significantly delayed tumor development in another.
