Electronic Noses in Medical Diagnostics

Area of Science:

• Biomedical Engineering
• Analytical Chemistry
• Medical Diagnostics

Background:

• Electronic nose (e-nose) technology mimics biologic olfaction to analyze complex volatile mixtures.
• E-nose applications in medicine aim to identify and discriminate between various diseases.
• This review summarizes research on e-nose devices and sensor technologies in medical diagnostics.

Purpose of the Study:

• To provide a comprehensive overview of research utilizing electronic noses for medical diagnostic applications.
• To highlight current trends and sensor technologies relevant to medical diagnostics.

Main Methods:

• A systematic search of bibliographic databases was conducted to identify relevant peer-reviewed literature.
• Retrieved papers were assessed for quality and relevance.
• Information was critically reviewed and compiled, including sample collection, data processing, and e-nose models.

Main Results:

• Most reviewed studies report promising results, with some e-nose applications exceeding the accuracy and sensitivity of established diagnostic methods.
• A limited number of e-nose devices have undergone field testing.
• Methods for sample collection and data processing, along with specific e-nose models, were tabulated.

Conclusions:

• Electronic nose devices, despite not being in routine use, hold significant potential for improving medical diagnostics.
• Their prospective application could address existing diagnostic challenges and advance preventative medicine through widespread non-invasive screening.
