Abstract
Methods for improving measurements of bacterial growth, such as mass, in Suspended Microchannel Resonators (SMR's). Methods include techniques to provide for bacterial growth over time in response to changing fluid environment to aid in determining parameters such as drug resistance and drug susceptibility. In particular the methods include trapping multiple bacteria in the SMR for a time period and varying the fluid to include sequences of nutrients and antibiotics, and measuring the rate of mass change of the bacteria in response to the changes in fluid composition.
