Researchers at Johns Hopkins have devised a way to detect whether cells previously transplanted into a living animal are alive or dead, an innovation they say is likely to speed the development of cell replacement therapies for conditions such as liver failure and type 1 diabetes. As reported in the March issue of Nature Materials, the study used nanoscale pH sensors and magnetic resonance imaging (MRI) machines to tell if liver cells injected into mice survived over time.
Using Laser Technology, Aleksandr Ovsianikov from the Vienna University of Technology wants to create microstructures with embedded living cells. This project will be funded by an ERC Starting Grant.
Queensgate Instruments has launched the new, faster, more responsive 500µm Z-Stage with Dual Sensor Technology™ at SPIE Photonics West 2013 in San Francisco.
The texture of breast cancer tissue differs from that of healthy tissue. Using a cutting-edge tissue diagnostic device, a group of researchers in Basel, Switzerland, has determined one key difference: cancerous tissue is a mix of stiff and soft zones, whereas healthy tissue has uniform stiffness.
The treatment of central nervous system (CNS) diseases can be particularly challenging because many of the therapeutic agents such as recombinant proteins and gene medicines are not easily transported across the blood-brain barrier (BBB).
The scientists, from Imperial College London, say their research brings them another step closer to a new kind of industrial revolution, where parts for these biological factories could be mass-produced. These factories have a wealth of applications including better drug delivery treatments for patients, enhancements in the way that minerals are mined from deep underground and advances in the production of biofuels.
On January 30, 2013 ACS Nano published a study by Ali Khademhosseini, PhD, MASc, a researcher in the division of biomedical engineering at Brigham and Women's Hospital, detailing the creation of innovative cardiac patches that utilize nanotechnology to enhance the conductivity of materials to induce cardiac tissue formation.
Optofluidics announces the pre-release of its Molecular NanoTweezer system - the most powerful optical trapping technology in the world – at SPIE Photonics West, BiOS and Biophysical Society annual meetings in Feb. 2013. Many thousands of times more powerful than the current state-of-the-art technology, the Molecular NanoTweezer allows rapid and automated handling of the smallest of particles including proteins, viruses, cells as well as inorganic nanoparticles.
By cloaking nanoparticles in the membranes of white blood cells, scientists at The Methodist Hospital Research Institute may have found a way to prevent the body from recognizing and destroying them before they deliver their drug payloads. The group describes its "LeukoLike Vectors", or LLVs, in the January issue of Nature Nanotechnology.
Nanostart-holding MagForce AG (Frankfurt, XETRA: MF6), a leading medical technology company in the field of nanomedicine in oncology, today announced the start of a research project with the University of Bremen, Center ...
