An article from The Science Daily talks about researchers working on bioelectronic noses and how they can detect spoiled food or something dead. When food rots, a repulsive smell comes out, and that is due to a bacterial reaction involving lysine, which is an amino acid. Researchers wanted to create receptors that were affinity for cadaverine, which basically helps zebrafish sense something rotting or dead. Scientists turned E. coli as a host cell, and protein was made in a bacterial cell. Seughun Hong and his colleagues wanted to see if these receptors they created was able to put into nanodiscs that can detect cadaverine. The scientists were successful at putting the receptors into nanodiscs, which led to creating a bioelectric nose which can detect rotting or dead things. This was a very cool article but very short. This topic can help out with finding bodies during investigations. Its cool to see how a bioelectric nose can detect dead things, how science can revolutionize implementing cells with technology.
