Dog Nose to E-Nose in Disease Diagnosis

Dog has natural gift of better smelling power which can be exploited for several purposes and disease diagnosis is one amongst them. The work on the use of dog nose in disease diagnosis is in preliminary stage. The electronic noses/e-noses are sensor based physical devices which are used to detect and analyse the various volatile organic compounds (VOCs) specific for health disorders including cancer to metabolic and infectious diseases. The sensor based disease diagnosis is also in preliminary stage. The data generated through studies conducted on disease diagnosis using one of the best noses of the universe may improve the sensitivity and specificity of existing e-noses to add par and this refined artificial intelligence, web data bases and sophisticated hardware and software may play in future a major role in field of diagnosis, monitoring and surveillance of human and animal diseases.
