Nanoemulsion droplets hold big promise for NMR/MRI

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 Imaging), as these xenon carriers can be used to detect the presence and spatial distribution of specific molecules with far greater sensitivity than conventional NMR/MRI.

Micro and nanotechnologies for space applications (ESA roundtable)

Micro and nanotechnologies (MNT) for space applications will be the theme of this important meeting. It will take place in the new Swiss Tech Convention Center on 10-13 June 2014 and will host members from national delegations, space agencies, space and MNT industries, research centrers and universities.

Sculpting flow - making waves at the microscopic level

Researchers report on a new way of sculpting tailor-made fluid flows by placing microscale pillars in microfluidic channels. The method could allow clinicians to better separate white blood cells in a sample, increase mixing in industrial applications, and more quickly perform lab-on-a-chip-type operations.

Novel quantum dot-based technique sees 100 different molecules in a single cell

Better diagnosis and treatment of cancer could hinge on the ability to rapidly map out networks of dozens of molecules in individual tumor cells. New research from the University of Washington offers a more comprehensive way of analyzing a single cell's unique behavior and could reveal patterns that indicate why a cell will or will not become malignant.

Nanoparticles help disrupt tumor blood supply, destroy tumors

Researchers have shown that they can use a gold nanoparticle tumor necrosis factor-alpha system to enhance the effects of either thermal therapy or cryosurgery. Moreover, they demonstrated that they can use standard magnetic resonance imaging technology to visualize tumor destruction.

Boosting immune therapy for cancer with nanoparticles

Activating the body's immune system to attack cancer and prevent it from recurring is one of the Holy Grails of cancer research because of its ability to specifically target cancer and to search almost anywhere in the body for rogue tumors. While the field has made some progress, and immune therapy for malignant melanoma and prostate cancer is proving its value in the treatment of human disease, it appears that no one general approach is going to work in all types of cancer. Two recent papers show how nanoparticles could become important tools for stimulating the immune system to respond to cancer.

'Nanotrain' targets tumors with anticancer agents

Investigators at the University of Florida have developed what they are calling a 'DNA nanotrain' that fast-tracks its payload of cancer-fighting drugs and bioimaging agents to tumor cells deep within the body. These nanotrains have the potential to cost-effectively deliver high doses of drugs to precisely targeted cancers using biocompatible materials that fall apart into non-toxic components once their payload is delivered.

One nanoparticle plus one antibody equals targeted drug delivery to tumors

Herceptin and camptothecin are both powerful anticancer agents with key characteristics that limit their effectiveness in treating cancer. Patients treated with Herceptin, a monoclonal antibody that targets a growth promoting factor common to breast cancers, often relapse as their tumors become resistant to the drug. Overcoming camptotheci's toxicity and low solubility represent major therapeutic challenges. Now, researchers have used nanotechnology to combine the two into what so far appears to be a highly effective drug for treating aggressive breast cancer.
