Embodiment

[0026] The present invention adopts bionic technology and layer-by-layer electrostatic self-assembly nano-composite technology to carry out molecular assembly on the conductive polymer (conducting polymer), so that its area is 0.01cm 2 There are a certain number of human-like olfactory receptors on the surface, which can respond to different odor signals and generate corresponding "molecular-level" electrical signals, and then prepare bionic olfactory sensing materials with biological olfactory sensing functions and characteristics.

[0027] The structure of human olfactory olfactory cells is shown in Figure 1. The present invention uses biophysical theory and biomedical engineering technology to study the mechanism of human olfactory sensitivity.

[0028] From the perspective of bioelectronics, when an odor acts on the olfactory epithelium, a polarized sensory potential is generated on the cell body membrane of the olfactory cell, and causes different frequency potential outpu...

Abstract

The invention discloses a bionic olfaction sensing material and preparing method based on conductive polymer, which is characterized by the following: reconstructing molecular structure of conductive polymer; assembling molecule; modifying physical property; adopting layer-to-layer electrostatic self-assembling elementary; dissolving conductive macromolecule to adsorb in the different base surfaces and layers; forming multi-layer heterogeneous structure.

Description

Technical field: [0001] The invention relates to a bionic olfactory sensing material based on a conductive polymer and a preparation method thereof, and belongs to the modification technology of the bionic olfactory sensing material based on a conductive polymer and a preparation method thereof. Background technique: [0002] At present, no functional material with olfactory sensitivity has been found in nature. In addition, due to the lack of theoretical understanding of the formation mechanism of biological olfaction and the lack of sensing technologies and means to effectively obtain olfactory signals, the research on bionic olfaction has been in a state of slow progress for many years. The winners of the 2004 Nobel Prize in Physiology / Medicine, American scientists Richard Axel and Linda Buck, cracked the "mystery of smell" that has never been recognized, discovered the structure of odor receptors and the olfactory system, and laid the foundation for bionic olfactory sens...
