Abstract:We demonstrate operation of a micropore based flow cytometer in the radio-frequency range. Apart from simply counting micron sized particles, such as cells, with close to nano-second resolution this counter offers the additional benefit of delivering insight into the intracellular environment. Such non-invasive screening of the cell’s interior based on analysing amplitude and phase of the signal is helpful in characterizing the biological activity of cells. In detail we are using heterodyne mixing to demodulat… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
