'Nano-tweezers' for single cell biopsy

Loading player...
How can seemingly similar cells behave differently? This is a particularly important question when a small change means that a cell does not function properly and several diseases might be the result of these small changes at the single cell level. But a cell is a complex system, and some of the important molecules inside a cell exist in very small quantities that can be difficult to detect. To address this challenge, a new tool has been developed called 'nano-tweezers'. These tiny devices can extract individual molecules from inside cells. Hannah Laeverenz Schlogelhofer spoke with Joshua Edel from Imperial College London about these 'nano-tweezers'.
