1. A method of fabricating a bioelectronic component, the method comprising the steps of:
- a. providing a batch of nanoparticles having submicron sizes and an electrical characteristic;
b. attaching at least one biological material to the nanoparticles so as to form shells of the biological material therearound, wherein the biological material is selected from the group consisting of proteins, polypeptides, nucleic acids, polysaccarides, carbohydrates, enzyme substrates, antigens, antibodies, pharmaceuticals, and combinations thereof;
c. depositing onto a surface the nanoparticles coated with shells attached thereto; and
d. causing the deposited nanoparticles to be in electrical communication with at least one electrical contact to facilitate an electrical measurement thereof, the electrical measurement being affected by the biological material.

Abstract
Bioelectronic components are formed using nanoparticles surrounded by attached shells of at least one biological material. The nanoparticles are deposited (e.g., using a printing process) onto a surface, and by associating the deposited nanoparticles with one or more electrical contacts, electrical measurement across the nanoparticles (and, consequently, across the biological material) may be made. A finished component may include multiple layers formed by nanoparticle deposition.
