A scanning probe microscopy probe, comprising:
- a chip;
- a mechanical resonator attached to the chip;
- a tip attached to the mechanical resonator;
- and
- a handle attached to the chip;
- a coating covering both the chip and the handle;
- wherein a portion of the handle distal to the chip and electrically connected to the chip is configured to make an electrical connection with an electrical controller;
