Abstract
A technique for determination of the dielectric constant of individual hemoglobin molecules is presented. It is based on modeling the profiles of their images obtained using electrostatic force microscopy. The obtained values of the static dielectric constant are in agreement with the known literature data. The proposed method can be adapted to determine the dielectric characteristics of individual molecules of various proteins.
