'Stealth' Probe Emplaced in Membrane (image) Stanford University Share Print E-Mail Caption A "stealth" probe sits firmly fused into a cell membrane. The membrane is represented by the small blue spheres, with the hydrophobic portion inside shown by squiggly fine blue lines. The silicon part of the probe is black and the chromium bands that bound the thin gold band are silver-gray. The gold band is obscured by the carbon atoms that are attached to it and that integrate with the hydrophobic part of the membrane.
