Scientists invent a new kind of nanoscale imaging for living cells

Scientists invent a new kind of nanoscale imaging for living cells They also move, and all that motion makes it practically impossible to get good high-resolution images of cells and what’s inside them.To get around this, a team of scientists from the University of Texas at Austin have put their heads together and demonstrated a whole different way of imaging cells, called “thermal noise imaging.

Researchers create a tiny tractor beam that totes bacteria around

Researchers create a tiny tractor beam that totes bacteria around “The principle underlying this laser beam is similar to the concept to be found in the television series Star Trek,” says Dr.In their new method, the Bielefeld researchers use a second laser beam as a single-cell optical trap — in other words, a tiny tractor beam — so that the cells float under the microscope and can be moved at will.
