US Patent 7492161 - Electrolytic nanoprobe

This patent teaches a new tool designed to study the electrical behavior of mitochrondria cells. Claim 1 reads:

1. A nanosized electrical probe for measuring an electrical signal of charged colloidal particles, which is fabricated from a quartz capillary and has a tip diameter of 50-100 nm, wherein the nanosized electrical probe is filled with an electrolytic solution, and thus has a tip resistance of 100 to 150 Mohms.
