Do you or someone you know suffer from allergies such as peanut, cows’ milk protein or egg? If so, the researchers at DBV-Technologies (www.dbv-technologies.com/en) will have no trouble grabbing your attention. This Paris-based firm has been working on a patch-centred solution to allergies for some time now, and its efforts have borne fruit in the shape of a number of different versions, each designed to tackle a specific allergy. For instance, this section of the DBV-Technologies website will introduce you to Viaskin Egg, whilst there are other sections dedicated to peanut and milk allergies.
The patches you see below appear relatively low-tech, but appearances can be deceptive. In fact, they consist of a titanium backing, which is then covered with an electrically-charged stream of antigens. Upon application on the skin, a condensation chamber forms between the epidermis and the backing, turning the antigens in their dry, powdered form into soluble form, enabling them to be delivered through the skin without entering the bloodstream directly. It is this method of delivery that makes the patch approach safer (in terms of being less likely to trigger anaphylaxis), than more traditional methods.
