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.

Read moreNovel 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.

Read moreBoosting 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.

Read more'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.

Read moreOne 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.
