## Abstract

A case containing DNA material protect the user from non-ionizing radiation emitted from a mobile phone, while protecting the phone from physical damage. The DNA material absorbs the radiation emitting from the transmitter of the mobile phone. Layers of DNA material along with non-organic layers are advantageously combine to increase the absorption. The DNA material may be used form the case or be provided and an insert to a prior art case.

## Claims

### Claim 1

A mobile phone case for the protection of the user from non-ionizing radiation comprising:
a back plate configured to receive the back side of the mobile phone, the back plate including a layer of DNA material at least in the area adjacent to the transmitting antenna of the mobile phone;
a plurality of sides attached to the back plate and configured to reversible retain the mobile phone within the case.

### Claim 2 (depends on 1)

The mobile phone case of claim 1, wherein the plurality of sides and the back plate comprise a layer of DNA material.

### Claim 3 (depends on 1)

The mobile phone case of claim 1, wherein the back plate comprises a plurality of Layers of DNA material, each layer being different from at least one of the other layers.

### Claim 4 (depends on 1)

The mobile phone case of claim 1, wherein the layer of DNA material is a composite material containing DNA material dispersed within it.

### Claim 5 (depends on 1)

The mobile phone case of claim 1, wherein the layer of DNA material is wood.

### Claim 6

A mobile phone case for protecting the mobile phone from physical damage, in which the case removable receives the mobile phone and allows for operation of the mobile phone while received in the case, the case including a back plate covering the back of the mobile phone, a top and bottom plate for covering the top and bottom of the mobile phone and side plates for covering the sides of the mobile phone, the top, bottom and side plates connected to the back plate, the improvement comprising:
an insert attached to the back plate and position between the back plate and the back of the mobile phone when the mobile phone is received by the case;
said insert comprising a plurality of layers of DNA rich materials for absorbing non-ionizing radiation.

### Claim 7 (depends on 6)

The mobile phone case of claim 6, wherein the insert further comprises at least one layer of non-organic material.

### Claim 8 (depends on 7)

The mobile phone case of claim 7, wherein the at least one layer of non-organic material is an adhesive for adhering the insert to the case.

### Claim 9 (depends on 7)

The mobile phone case of claim 7, wherein the at least one layer of non-organic material contains ferrite.

### Claim 10 (depends on 6)

The mobile phone case of claim 6, wherein the plurality of layers of DNA rich material include an epoxy with DNA materials dispersed within.

### Claim 11

An insert for a mobile phone case to protect the user from non-ionizing radiation emitted from the transmitter of a mobile phone, the insert comprising:
a layer of DNA material; and,
a layer of adhesive permanently affixed to the layer of DNA material;
a slip sheet removable attached to the layer of adhesive, wherein the slip sheet protects the adhesive properties of the adhesive prior to removal;
wherein the insert is flat and thin and configured to fit between a mobile phone case and the mobile phone when received by the mobile phone case.

### Claim 12 (depends on 11)

The insert of claim 11, wherein the insert further comprises at least one layer of non-organic material.

### Claim 13 (depends on 12)

The insert of claim 12, wherein the adhesive comprises non-organic material.

### Claim 14 (depends on 12)

The insert of claim 12, wherein the at least one layer of non-organic material contains ferrite.

### Claim 15 (depends on 11)

The insert of claim 11, wherein the insert further comprises a plurality of layers of DNA rich material.

### Claim 16 (depends on 15)

The insert of claim 15, wherein the plurality of layers of DNA rich material includes an epoxy with DNA materials dispersed within.
