The Mind Lab, an independent consultancy in the UK, studies the odor of a building as part of research on the brain's responses to stimuli. [17] Real estate brokers have been recommending to their clients to have smells of freshly baked cookies or the aroma of coffee in the house when it is being presented to potential buyers to create a sense ...
Since 1982, [2] research has been conducted to develop technologies, commonly referred to as electronic noses, that could detect and recognize odors and flavors. The stages of the recognition process are similar to human olfaction and are performed for identification, comparison, quantification and other applications, including data storage and ...
Researcher sampling the volatile organic compounds of a historic book using solid phase microextraction at the Heritage Science Lab in University College London Institute for Sustainable Heritage. Olfactory heritage science is an emerging field of research, focused on the scientific techniques to analyse, document and preserve odours and the ...
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
The vibration theory of smell proposes that a molecule's smell character is due to its vibrational frequency in the infrared range. This controversial theory is an alternative to the more widely accepted docking theory of olfaction (formerly termed the shape theory of olfaction), which proposes that a molecule's smell character is due to a range of weak non-covalent interactions between its ...
Today's modern advancements in biotechnology and nanotechnology are enabling digital scent technology to assist several industry sectors, including the medical technology, nanotechnology sectors, [2] [3] as well the entertainment and fashion industry sectors, as perfumers are utilizing this technology on neurological, emotional and psychological levels.

Smell as evidence of disease has been long used, dating back to Hippocrates around 400 years BCE. [1] It is still employed with a focus on volatile organic compounds (VOCs) found in body odor. [ 2 ] VOCs are carbon-based molecular groups having a low molecular weight, secreted during cells' metabolic processes. [ 3 ]
