Summary
Electronic noses (EN) offer a non-invasive, rapid, and cost-effective method for pulmonary diagnostics by analyzing volatile organic compounds (VOCs). These electronic sensing systems show promise for medical applications in respiratory medicine.
Area of Science:
- Respiratory Medicine
- Biomedical Engineering
Context:
- Non-invasive pulmonary diagnostics are crucial for respiratory medicine.
- Exhaled breath condensate is a traditional method, but faster techniques are emerging.
- Electronic noses (EN) offer a promising alternative for analyzing breath.
Purpose:
- To review the current state of electronic nose technology for non-invasive pulmonary diagnostics.
- To highlight the principles and applications of EN in detecting volatile organic compounds (VOCs) in breath.
- To discuss the advantages and potential of EN in medical settings.
Summary:
- Electronic noses utilize biopolymer sensors to detect patterns of volatile organic compounds (VOCs) in exhaled breath.
- Sensing mechanisms involve VOC binding to sensors, causing physical changes and resistance shifts.
- Pattern recognition algorithms analyze these 'smell prints' for diagnostic purposes, with some ENs capable of identifying single analytes.
Impact:
- EN offer non-invasive, onsite, and cost-effective sampling for respiratory diagnostics.
- Promising research results indicate significant potential for EN in clinical applications.
- This technology could revolutionize how respiratory diseases are diagnosed and monitored.

Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Physiology of Smell and Olfactory Pathway
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
Microbial Biosensors
Microbial biosensors are analytical devices that utilize living microbes to detect specific substances through measurable signals. These devices consist of two main components: biosensing organisms and signal-transducing elements. Biosensing organisms, such as Escherichia coli or Saccharomyces cerevisiae, are typically housed in multiwell plates connected to transducers, enabling rapid, real-time detection of target analytes.Signal Generation MechanismWhen a target analyte—such as...
