Nanodevices for tracking the physics of biological cell physiology (video)
Scientists have now introduced tiny tracking devices into mammalian cell interiors for the first time to provide a unique glimpse into the early stages of development. The work done on single-cell embryos will change our understanding of the mechanisms underlying cellular behavior in general and could provide insight into ageing and diseases.
Professor Tony Perry, from the Department of Biology and Biochemistry, University of Bath, conducted the research. He injected a silicon-based microdevice along with sperm in the mouse egg cell. The result was an egg that was fertilised and contained a tracking device.
The spider-like devices have eight flexible legs. The legs are able to measure ‘pulling’ and ‘pushing’ forces in the cell’s interior with a high degree of precision. This reveals the forces at work and shows how intracellular matter has rearranged over time.
