Over the past couple of decades, atomic force microscopy (AFM) has emerged as a powerful tool for imaging surfaces at astonishing resolutions - fractions of a nanometer in some cases. But suppose you're more concerned with what lies below the surface? Researchers have shown that under the right circumstances, surface science instruments such as the AFM can deliver valuable data about sub-surface conditions.

National Institute of Standards and Technology (NIST) scientists have moved a step closer to developing the means for a rapid diagnostic blood test that can scan for thousands of disease markers and other chemical indicators of health. The team reports it has learned how to decode the electrical signals generated by a nanopore - a 'gate' less than 2 nanometers wide in an artificial cell membrane.

Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique by Rice University researchers will allow them to track single molecules without modifying them - and it works over longer timescales.
