Lab-on-a-chip teaching kit - a nanolab in the classroom

The fourth conference in the Twente Mastership series will be held at the University of Twente on Thursday 26 January. This conference is intended to build bridges between secondary and higher education. The theme of the conference is "from research to teaching concept".

Novel strategy improves cancer cell uptake of nanoparticles

Researchers at Harvard Medical School and the Massachusetts Institute of Technology have developed a strategy for identifying what could be called tumor uptake molecules for use on nanoparticles. This new class of tumor-targeting agents boosts the amount of drug-loaded nanoparticles that get into cancer cells.

Overcoming cancer drug resistance with nanoparticles

One of the ways in which cancer cells evade anticancer therapy is by producing a protein that pumps drugs out of the cell before these compounds can exert their cell-killing effects. A research team at Northwestern University has found that biocompatible iron oxide-titanium dioxide nanoparticles can bypass this pump and enable DNA-damaging anticancer drugs to reach the cell nucleus.

Bismuth nanoparticles provide high fidelity images of breast tumors

By combining a nanoparticle that is readily visible in X-ray computed tomography (CT) scans with a molecule that targets tumor lymph vessels and other tumor tissues, a research team from the University of California, San Diego (UCSD) and the Sanford-Burnham Medical Research Institute has developed a new imaging agent that provides high-fidelity CT images of tumors and their edges.

Designing chemical catalysts: There's an app for that

Five scientists from the SUNCAT Center for Interface Science and Catalysis, at SLAC National Accelerator Laboratory and Stanford's Department of Chemical Engineering, have a solution for those who design new chemical catalysts: They made an app.

Nanoscale bouncing gold droplets

When a pebble is dropped onto the surface of a pond, a droplet of water bounces up from the surface. The same thing happens when a focussed laser-beam strikes the surface of a thin metal film - the metal can be locally melted by the laser light and it can bounce up from the metal surface as a metallic droplet. Researchers now show that this phenomenon can be used to make nanoscale metallic droplets.
