A new technique is presented for bio/chemical sensors, based on microcantilevers, for detection in liquid environment. The low quality factor of the cantilever in liquid is increased up to three orders of magnitude by using Q-control. This enables AC detection that is immune to the long-term drift of the DC cantilever response in liquids, and to temperature(More)
The assessment of the complete distribution of nanoparticle sizes within a suspension is notoriously difficult to carry out. We demonstrate the Nanoparticle Tracking Analysis (NTA) technique that sizes nanoparticles in suspension, based on their Brownian motion. This technique has found significant use in the field of nano- and eco-toxicology, in several(More)
Aftercare programs allow patients to continue to exercise with supervision following discharge from physical therapy. Although not yet widespread in clinical practice, aftercare programs represent a growing trend following outpatient physical therapy settings in the United States. The purpose of this study was to explore and describe the characteristics,(More)
