A nanotechnology holy grail in label-free cancer marker detection: Single molecules

Just months after setting a record for detecting the smallest single virus in solution, researchers at the Polytechnic Institute of New York University announced a new breakthrough: A nano-enhanced version of their biosensor detected a single cancer marker protein and even smaller molecules below the mass of all known markers. This achievement sets a new benchmark for the most sensitive limit of detection, and may significantly advance early disease diagnostics.

Ancient technology for metal coatings 2,000 years ago can't be matched even today

Artists and craftsmen more than 2,000 years ago developed thin-film coating technology unrivaled even by today's standards for producing DVDs, solar cells, electronic devices and other products. Understanding these sophisticated metal-plating techniques from ancient times could help preserve priceless artistic and other treasures from the past.

Watching molecule movements in live cells

The newly developed STED-RICS microscopy method records rapid movements of molecules in live samples. By combining raster image correlation spectroscopy (RICS) with STED fluorescence microscopy, researchers of Karlsruhe Institute of Technology (KIT) opened up new applications in medical research, e.g. analyzing the dynamics of cell membranes at high protein concentrations.

Copper nanoparticles could protect food from bacteria

Researchers discovered how to embed nanoparticles of the red metal into vermiculite, an inexpensive, inert compound sometimes used in potting soil. In preliminary tests on local lake water, it killed 100 percent of E. coli bacteria in the sample.
