Nanoparticles cut off ‘addicted’ tumors from source of their survival
By Bill Hathaway
Yale biologists and engineers have designed drug-loaded nanoparticles that target the soft underbelly of many types of cancer — a tiny gene product that tumors depend upon to replicate and survive.

Gold particles deliver more than just glitter
Nanoparticles could carry drugs to treat cancer, other diseases
The top image shows a mixture of gold nanoparticles. The longer particles are called
nanobones, and the smaller are nanocapsules. Bottom left: After the nanoparticles are
hit with 800 nanometer wavelength infrared light, the nanocapsules melt and release their
payload. Nanobones remain intact. Right: After the nanoparticles are hit with 1100 nanometer
wavelength infrared light, the nanobones melt and release their payload. Nanocapsules
remain intact. Image / Andy Wijaya

Penn Engineers Create Carbon Nanopipettes That Are Smaller Than Cells and Measure Electric Current
PHILADELPHIA –- University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. Researchers developed this tiny carbon-based tool to probe cells with minimal intrusion and inject fluids without damaging or inhibiting cell growth.Gold Nanoparticle Probes May Allow Earlier Cancer Detection
Using tiny gold particles embedded with dyes, researchers have shown that they can identify tumors under the skin of a living animal. These tools may allow doctors to detect and diagnose cancer earlier and less invasivelyNano-sized voltmeter measures electric fields deep within cells
ANN ARBOR, Mich.—A wireless, nano-scale voltmeter developed at the University of Michigan is overturning conventional wisdom about the physical environment inside cells. It may someday help researchers tackle such tricky medical issues as why cancer cells grow out of control and how damaged nerves might be mended.
