Optical magnetic microscope for high-resolution, wide-field cell imaging
Cancer diagnosis breakthrough
Multifunctional nanoparticle enables new type of biological imaging
Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique ...
Game-changing nanodiamond discovery for MRI
A Northwestern University study shows that coupling a magnetic resonance imaging (MRI) contrast agent to a nanodiamond results in dramatically enhanced signal intensity and thus vivid image contrast.
Nanoparticles on track to distinguish tumour tissue
Gold nanoparticles could be used to help detect the margins between tumours and normal tissue, enabling surgeons to better determine which tissue to remove and which to leave.
Researchers combine weak chemical forces to strengthen novel imaging technology
(Phys.org) —When University of Illinois Associate Professor of Chemical and Biomolecular Engineering Hyunjoon Kong, graduate student Cartney Smith, and colleagues set out to improve MR imaging (MRI), they ...
New ultrasound device may add in detecting risk for heart attack, stroke
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have developed a new ultrasound device that could help identify arterial plaque that is at high risk of ...
Nanoparticle pinpoints blood vessel plaques
A team of researchers, led by scientists at Case Western Reserve University, has developed a multifunctional nanoparticle that enables magnetic resonance imaging (MRI) to pinpoint blood vessel plaques caused by atherosclerosis. ...
A leap forward in X-ray technology
X-rays transformed medicine a century ago by providing a noninvasive way to detect internal structures in the body. Still, they have limitations: X-rays cannot image the body's soft tissues, except with the ...
New nanoparticle delivers, tracks cancer drugs
(Phys.org) —UNSW chemical engineers have synthesised a new iron oxide nanoparticle that delivers cancer drugs to cells while simultaneously monitoring the drug release in real time.
Bismuth-carrying nanotubes show promise for CT scans
Scientists at Rice University have trapped bismuth in a nanotube cage to tag stem cells for X-ray tracking.
Tiny bubbles hold big promise for NMR/MRI
(Phys.org) —Berkeley Lab researchers have shown that tiny bubbles carrying hyperpolarized xenon gas hold big promise for NMR (nuclear magnetic resonance) and its sister technology, MRI (Magnetic Resonance ...
New X-ray method shows how frog embryos could help thwart disease
An international team of scientists using a new X-ray method recorded the internal structure and cell movement inside a living frog embryo in greater detail than ever before.
New model facilitates predictions about how nanoparticles form, gives clues about how process can be controlled
(Phys.org)—Nanoparticles are versatile harbingers of hope: They can serve as active medical agents or contrast media just as well as electronic storage media or reinforcement for structural materials. Researchers ...
