Nanomechanical sensor detects levels of antibiotics in blood

A new methodology for rapidly measuring the level of antibiotic drug molecules in human blood serum has been developed, paving the way to applications within drug development and personalised medicine.

The study, published today in Nature Nanotechnology (“Surface-stress sensors for rapid and ultrasensitive detection of active free drugs in human serum”), describes the exploitation of a sensor for measuring the concentration of effective antibiotics in blood, giving an indication of their efficiency against disease causing pathogens, for instance multidrug resistant hospital “superbugs”.

This development could potentially give a far greater understanding of the effectiveness of drug dosages required for different individuals, reducing potential toxic effects, allowing personalised treatment for patients and leading to new insights into optimal clinical regimes, such as combination therapies. … (Read more)
