Lasers Embedded Inside Cells to Help Track Spread of Cancer
Lasers Embedded Inside Cells to Help Track Spread of Cancer
 The field of medicine sees advances in miniaturization on a regular basis, but **w we’re almost shocked by the fact that researchers at the University of St Andrews in the UK managed to introduce microscopic Lasers into the interior of live cells. While at first it might seem as practical as attaching lasers to sharks’ heads, the tech**logy actually has great potential in biomedical applications for tracking individual cell movements within a living body.Optical resonators that generate a coherent beam of light have previously been too large to fit Inside a cell, but the researchers behind the latest research published in Na** Letters managed to scale the core of a laser that it can fit Inside of white blood cells. The so-called*fluorescent whispering gallery mode (WGM) microresonators were introduced Inside of Cells by fooling*the natural endocytosis process which lets certain molecules pass through Cells walls. The target Cells were then illuminated by external pulses of light, activating the microresonators that immediately responded by beaming back green laser light. Because this laser light has optical characteristics that are unique to the cell that the microresonator finds itself in, all the Cells tagged this way can be tracked individually for days at a time as they migrate throughout the body. While the initial study focused on white blood cells, the researchers believe the tech**logy can be translated to other applications, including tracking how elusive circulating tumor Cells move from the primary tumor to invade other healthy targets.
