Abstract
Methods and apparatus for improving measurements of particle or cell characteristics, such as mass, in Susppended Microchannel Resonators (SMR's). Apparatus include in particular designs for trapping particles in SMR's for extended measurement periods. Methods include techniques to provide differential measurements by varying the fluid density for repeated measurements on the same particle or cell.
