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.

Controlling molecular self-assembly via different pathways

Researchers at Eindhoven University of Technology (TU/e) have succeeded in monitoring and controlling a molecular self-assembly process via different pathways. While it was formerly thought that the molecules form the right structure by themselves, this research shows that the assembly process can follow different pathways yielding different structures; in this case polymer chains with left- and right-handed helical directions.

Breast cancer cells targeted, then burned, by gold-filled silicon wafers

By shining infrared light on specially designed, gold-filled silicon wafers, scientists at The Methodist Hospital Research Institute have successfully targeted and burned breast cancer cells. If the technology is shown to work in human clinical trials, it could provide patients a non-invasive alternative to surgical ablation, and could be used in conjunction with traditional cancer treatments, such as chemotherapy, to make those treatments more effective.
