Nanometer scale instrument for biochemically, chemically, or catalytically interacting with a sample material
An instrument includes a probe having a porous tip, a tip positioning apparatus to position the tip with respect to a sample material, a probe positioning apparatus to position the probe and sample material with respect to each other, and a controller. The controller controls the probe positioning apparatus in positioning the probe over the sample and controls the tip positioning apparatus in lowering the tip into the sample material to produce an interaction between the porous tip and the sample material.
1. An instrument for biochemically, chemically, or catalytically interacting with a sample material, the instrument comprising:
a probe comprising:
a tip with a sharp end and a core material that extends to the sharp end, the core material having pores that form binding sites of a specific size for holding selected molecules;
tip positioning apparatus to position the tip with respect to a sample material;
probe positioning apparatus to position the probe and sample material with respect to each other;
a controller to (A) control the probe positioning apparatus in positioning the probe over the sample, and (B) control the tip positioning apparatus in lowering the tip into the sample material to pick up the selected molecules from the sample material, deposit the selected molecules in the sample material, or cause an attractive force between the selected molecules and molecules of the sample material.
2. The instrument of claim 1 wherein the core material comprises silicon that is porously etched at the sharp end of the tip.
