Recently published in the German scientific journal Angewandte Chemie, this research delves into a more comprehensive understanding of the intricate interconnections among components within cells. This topic has long been a focal point for scientists worldwide, providing valuable insights into the behaviors of certain diseases.

The team, employing SRS microscopy for cellular visualization, has successfully tackled the challenge of obtaining clear images of individual processes.

Previous attempts at multiplex optical detection in live cells were hindered by time-consuming analyses and difficulties arising from poor image quality. Moreover, these efforts were limited in tracking processes, often requiring physical alterations to the cell for clearer images.

In contrast, the presented work utilizes dyes that necessitate no adjustments to the cell itself, ensuring completion within minutes. Remarkably, it allows simultaneous tracking of up to nine different aspects of cell structure. This represents a significant breakthrough, surpassing the limitations of previous work, which could only track seven processes.

This work will provide scientists with a tool to garner lots of information out of cells within a short space of time. This has the potential to assist in understanding how current drugs developed for a range of applications are fighting disease and even provide hints on how to improve treatments.”
