Sruthi S. Balakrishnan | Jun 1, 2021
Differences in how researchers prepare and image samples can lead to discrepancies in their results.
Cancerous Conduits
Amanda B. Keener | Apr 1, 2016
Metastatic cancer cells use nanotubes to manipulate blood vessels.
The Cancer-Test Kid
Dan Cossins | Apr 1, 2013
After a family friend died of pancreatic cancer, high school sophomore Jack Andraka invented a diagnostic strip that could detect the disease in its early stages.
Next Generation: Breathing Nanotubes
Sabrina Richards | Sep 20, 2012
Flexible nano-sized tubules that self-assemble could be a step forward for dynamic nanostructures and perhaps drug delivery.
