## Abstract

Viruses, including corona viruses such as COVID-19, are often present in the mouth or nose of a person before they infect the body. The disclosed electrochemical device destroys or denatures viruses in the mouth or nose rendering the viruses ineffective to cause infection by applying a low voltage potential to the mucus. The device has a potentiostat powered by a small battery embedded in a plastic frame that fits in a person's mouth. The device has electrodes to contact the mucus of the mouth or nose. The mucus serves as electrolyte, conducting ions as well as viruses with their protein “skin” towards the electrode. The viruses are adsorbed onto the metal probes where the electrical current denatures the protein skin of the virus rendering the virus ineffective to cause infection.

## Claims

### Claim 1

An apparatus comprising:
a mount configured to fit in the mouth or nose of a person;
a potentiostat having two electrodes, a working electrode and a counter electrode;
a battery;
said working electrode having a first insulating layer; and
said counter electrode having a second insulating layer.

### Claim 2 (depends on 1)

The apparatus of claim 1 further comprising:
a reference electrode;
said reference electrode having a third insulating layer.

### Claim 3 (depends on 1)

The apparatus of claim 1 further comprising:
a wireless transceiver; and
said potentiostat having a voltage that is adjustable via the wireless transceiver.

### Claim 4 (depends on 1)

The apparatus of claim 1 further comprising:
said potentiostat having adjustable voltage; and
a manual dial for adjusting voltage.

### Claim 5

An apparatus comprising:
a mounting apparatus having a battery, a working electrode, and a counter electrode;
said mounting apparatus configured to be inserted in a person's mouth having mucosa and mucus;
said working electrode having a first metal probe and a first insulator wherein the first insulator is positioned between the mucosa and the first metal probe;
said counter electrode having a second metal probe and a second insulator wherein the second insulator is positioned between the mucosa and the second metal probe.

### Claim 6 (depends on 5)

The apparatus of claim 5 further comprising:
a potentiostat.

### Claim 7 (depends on 6)

The apparatus of claim 6 further comprising:
a reference electrode.

### Claim 8 (depends on 6)

The apparatus of claim 6 further comprising:
said potentiostat having adjustable voltage; and
a manual actuator for adjusting voltage.

### Claim 9 (depends on 6)

The apparatus of claim 6 further comprising:
said potentiostat having adjustable voltage and a wireless transceiver.

### Claim 10

An apparatus comprising:
a means for holding a first metal probe in contact with mucus in the mouth without the first metal probe coming in contact with mucusa in the mouth;
a means for holding a second metal probe in contact with mucus in the mouth without the second metal probe coming in contact with mucusa in the mouth;
a means for holding a reference metal probe in contact with mucus in the mouth without the reference metal probe coming in contact with mucosa in the mouth;
a battery;
a potentiostat having a voltage; and
a means to adjust the voltage of said potentiostat.
