QUANTITATIVE ANALYSIS OF MRNA AND PROTEIN EXPRESSION

摘要

Provided is a highly selective and non-destructive method and apparatus for the measurement of one or more target molecules within a target environment. The apparatus comprises of a modified AFM (atomic force microscope) tip to create a tapered nanoscale co-axial cable, and wherein the application of an alternating potential between the inner and outer electrodes of the co-axial cable creates a dielectrophoretic force for attracting molecules toward the tip-end which is pre-treated with one or more specific ligands.
