Innovative Approaches for Pre-Screening and Sensing of Diseases
Prescreening and sensing of diseases offers a number of benefits that can help in prevention of major diseases. The aim of disease pre-screening is to detect possible disorders or diseases in people who do not have any symptoms. Earlier screening methods for the detection of diseases was invasive, complicated, and would require extensive tests. Some conventional methods used in clinical diagnoses include many invasive and potentially hazardous biopsy procedures, endoscopy, computed tomography; numerous innovative approaches have evolved to overcome the limitations of traditional techniques. Non-invasive biomedical sensor, genomics, electronic nose, nano-material, plasmonicsensor devices, microfabrication-based technologies, flat-panel detectors, digital breast object models, endomicroscopy, breath biopsy, and wavelet-based enhancement methods are some of the emerging frontiers in prescreening and sensing of diseases. This chapter will provide an in-depth discussion of the abovementioned innovative techniques related to prescreening and sensing of diseases.
