The only constraint to the application of Aptamarkers to a pathology is the capacity to define clear differences between those affected by the pathology and those that are not. This means that this approach is applicable to all diseases regardless of the number of people affected, the severity of the disease, or the location in the body where the disease occurs. We have selected aptamers against a broad range of biological fluids, including blood, saliva, and perspiration. We have also selected aptamers directly against many types of tissue, especially brain tissue. Tissue selections are performed on sliced tissue on microscope slides. There is nowhere in the body that we cannot get an aptamer, or develop a diagnostic approach. We are open to collaborations on all types of diseases, including infectious diseases that are relatively difficult to diagnose for example Lyme’s disease.
