System and method for identifying proteins

摘要

A method is disclosed for identifying one or more specific proteins in a heterogeneous test solution with a plurality of micro-cantilevers which have two or more conductive arms coupled to an end area having a higher resistance than the conductive arms. The method includes the operation of heating each end area of the plurality of micro-cantilevers by passing a current through each end area. A further operation includes increasing a temperature of the heterogeneous test solution using each heated end area of each of the plurality of micro-cantilevers. Another operation involves measuring a temperature change in the heterogeneous test solution that occurs when a specific protein denatures while heating the heterogeneous test solution with the plurality of micro-cantilevers. A further operation includes identifying the one or more specific proteins in the heterogeneous test solution according to the temperature at which each of the specific proteins denatured.
