Implantable Device Offers Continuous Cancer Monitoring
Such implants could one day provide up-to-the-minute information about what a tumor is doing—whether it is growing or shrinking, how it is responding to treatment, and whether it has metastasized or is about to do so.

Nanoparticles Image Breast Cancer
A new report from investigators at the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology suggests that targeted iron oxide nanoparticles may serve as novel imaging agents for the early detection of breast tumors.

Nanoparticle-Based "Chemical Nose" Sniffs Out Cancer Earlier To Improve Treatment Options
Using a “chemical nose” array of nanoparticles and polymers, researchers at the University of Massachusetts Amherst have developed a fundamentally new, more effective way to differentiate not only between healthy and cancerous cells but also between metastatic and nonmetastatic cancer cells.

'Normal' cells far from cancer give nanosignals of trouble
A new Northwestern University-led study of human colon, pancreatic and lung cells is the first to report that cancer cells and their non-cancerous cell neighbors, although quite different under the microscope, share very similar structural abnormalities on the nanoscale level.

A chance observation leads to potential insights into the basis for cell damage associated with disorders like Alzheimer’s disease
Decades of research have failed to conclusively crack the mystery of how amyloid-associated diseases like Alzheimer’s do so much damage, but new findings by researchers at RIKEN suggest that part of the answer may lie in the structural rearrangements observed in plaque-forming proteins.

Nanotechnology may increase longevity of dental fillings
Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. A Medical College of Georgia researcher hopes a new nanotechnology technique will extend the fillings' longevity.

Early Detection of Pancreatic Cancer Closer Thanks to Multifunctional Nanoparticles
Emory University researchers have created tools for the early diagnosis of pancreatic cancer by attaching a molecule that binds specifically to pancreatic cancer cells to iron oxide nanoparticles that are clearly visible under magnetic resonance imaging (MRI).

Nanoscale Holes Provide Speed Boost for Diagnostic Tests
Microfluidic devices, essentially miniaturized chemical laboratories etched into material similar to a microprocessor chip, are revolutionizing diagnostic medicine by providing a technology platform that is more sensitive and less expensive than conventional analytical technologies.

Nanofluidic Biopsy Detects Subtle Changes in Cancer Cells
By taking two standard laboratory techniques—capillary electrophoresis and antibody-based protein detection—and shrinking them to the nanoscale, researchers at the Stanford University School of Medicine have created a new method for detecting miniscule changes in the levels of proteins associated with cancer.

Mathematical Model Predicts Factors Driving Tumor Invasion
Using a sophisticated mathematical model that relates a wide variety of biological variables to disease progression, a research team has shown that accounting for the shape and physical characteristics of the tumor margin and invasiveness of the tumor accurately predicts how a particular tumor will develop and metastasize.
