Donald Ingber on magnetic control of cellular signaling
A new technology developed by Donald Ingber, MD, PhD, Robert Mannix, PhD, and Mara Prentiss, PhD, allows for the magnetic control of living cells using magnetic forces rather than chemicals and hormones. The researchers devised a way to get tiny beads --30 nanometers in diameter -- to bind to receptor molecules on the cell surface. When exposed to a magnetic field, the beads themselves become magnets, and pull together through magnetic attraction. This pull drags the cell's receptors into large clusters, mimicking what happens when drugs or other molecules bind to them. [Go to the press release...]
