HOT: cheap PDMS biochip with integrated cell positioning for imaging live cells with TIRF microscopy

A cheap PDMS biochip has been developed by Roland Thuenauer and Alois Sonnleitner, Center for Advanced Bioanalysis, Austria, that enables the recording of individual vesicle fusion events at the apical membrane of live cells.

The cells can be grown to polarize directly on the device and then correctly placed by an integrated micro-positioning system in order to perform apical TIRF microscopy, without the need for an additional weight to force the apical membrane of the cells into the region of the evanescent wave.

As with all our hot articles, this one’s free to access for 4 weeks – why not take a look:
