Nanochip are often print in 70 nm, 50 nm, and 40 nm. That is smaller than a X-ray or MRI WHO have a limit of 150 nm When Scan pictures. It means that the small print nanochip have no diffraction, and light ans sound pass right thrugh the metal without reflect, the MRI and X-ray show no picture, When Scan the nanochip. Like Rambo Microchip. It cloud be RFID, CMOS mems sensor, BULK SAW filter print in nanoscale smaller then 150 nm.
