infocus #66 June 2022 Rising possibilities of quantitative phase imaging
Quantitative phase imaging (QPI) technology is on the rise. Several main factors have contributed to its popularity. Live-cell imaging is the key approach to cell analysis in both primary and applied research. QPI enables researchers to perform long-term experiments on live cells without altering their nature thanks to its label-free approach to analysis.
Despite the ongoing progress in the fluorescence microscopy (the development of less toxic and more stable fluorophores, low-power lasers and more sensitive detectors), label-free imaging remains crucial when monitoring cells in an undisturbed environment - for example, in drug testing studies or studies of differentiation.
