Conclusions

Nanotechnology is a fascinating area of development providing remarkable solutions in many fields including allergy, where it represents a promising tool for improving diagnosis and immunotherapy. The specific properties that nanostructures can offer, which are tuneable at will, provide the chance to design adequate systems to be applied in this field. There are wide panels of structures accessible, and controlling their physico-chemical properties would allow the obtainment of safer and more efficient compounds for our goals, either in diagnosis or treatment. Interesting tools for detection and diagnosis are available for clinicians and researchers in this field. In addition, relevant advances have been described for application of nanostructures in immunotherapy. Besides these promising facts found in the literature, the application of nanotechnology to allergy is still in its infancy and have to face new important challenges in the next years to achieve important goals.
