Use and making of biosensors utilizing antimicrobial peptides for highly sensitive biological monitoring
First Claim
1. A biosensor configured for application to a biological surface, the biosensor comprising:
- a microelectrode array disposed on a dissolvable substrate;
an anode and a cathode electrically coupled to the microelectrode array;
a resonant circuit with an inductive coil electrically coupled to the cathode and anode; and
a wireless telemetry unit electrically coupled to the resonant circuit, forming an electric circuit,the dissolvable substrate being configured to be dissolved off by the application of water, leaving the microelectrode array, resonant circuit and wireless telemetry unit intimately attached to the biological surface.

Abstract
A biosensor and method of making are disclosed. The biosensor is configured to detect a target and may include a peptide immobilized on a sensing component, the sensing component having an anode and a cathode. The immobilized peptide may comprise an antimicrobial peptide binding motif for the target. The sensing component has an electrical conductivity that changes in response to binding of the immobilized peptide to the target. The immobilized peptide may bind one or more targets selected from the list consisting of: bacteria, Gram-negative bacteria, Gram-positive bacteria, pathogens, protozoa, fungi, viruses, and cancerous cells. The biosensor may have a display with a readout that is responsive to changes in electrical conductivity of the sensing component. The display unit may be wirelessly coupled to the sensing component. A resonant circuit with an inductive coil may be electrically coupled to the sensing component. A planar coil antenna may be disposed in proximity to the resonant circuit, the planar coil antenna being configured to provide power to the sensing component.
