Methods and apparatus for improving measurements of particle or cell characteristics, such as mass, in Suspended 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.

Method and apparatus for trapping single particles in microfluidic channels

Method for determining buoyant mass and deformability of a cell. The method includes introducing the cell into a suspended microchannel resonator that includes a constriction near a distal location in the resonator. A first frequency shift in the resonator is monitored as a cell moves to the distal location in the resonator, the first frequency shift being related to the buoyant mass of the cell. Transit time of the cell through the constriction is measured by monitoring a second frequency shift as a result of a change in cell location as it passes through the constriction, whereby deformability is determined from the measured buoyant mass and transit time.

Apparatus and method for measuring buoyant mass and deformability of single cells

Methods and apparatus for improving measurements of particle or cell characteristics, such as mass, in Suspended Microchannel Resonators (SMR's). Apparatus include in particular designs for trapping particles in SMR's for extended measurement periods and for changing the fluid properties within the SMR during the extended periods. Methods include techniques to provide for cell growth over time and over time in response to changing fluid properties to aid in determining parameters such as drug resistance and drug susceptibility.

Method and apparatus for extended time and varying environment measurements of single particles in microfluidic channels
