Nanoscale Analysis Labs

FiReaNGeL writes "Imagine being able to rapidly identify tiny biological molecules such as DNA and toxins using less than a drop of salt water in a system that can fit on a microchip. It's closer than you might believe: in a paper appearing next week in PNAS, a team of researchers proves for the first time that a single nanometer-scale pore in a thin membrane can be used to accurately detect and sort different-sized polymer chains (a model for biomolecules) that pass through or block the channel. This could lead to rapid detection systems for pathogens and toxic chemicals."

Incremental development, not a new idea

[tygerstripes]

Just for those few who didn't already know and can't be arsed to RTFA, the lab-on-a-chip (LOC) idea has been around for years now. It's virtually a scientific field all of its own, and even has a journal.

This is an interesting development in LOC tech - I'm glad to hear about it - but the post makes it sound like a potential bloody paradigm-shift or something.
