Latest Patents

Saifei Feng holds a patent for a method titled "Method for selective detection of L-tryptophan using formaldehyde as medium." This invention involves the preparation of a copper sulfide nanosheets-chitosan/acidified functionalized multi-wall carbon nanotubes (CuS NS—CS/F-MWCNTs) composite material. The method includes creating a composite film-modified electrode CuS NS—CS/F-MWCNTs/GCE and detecting L-tryptophan. The invention addresses the challenge of overlapping oxidation peaks of L-tryptophan and L-tyrosine, providing a highly selective detection method through the Pictet-Spengler reaction of formaldehyde with L-tryptophan. This innovation effectively shifts the oxidation peak potential of L-tryptophan to 0.82 V, while that of L-tyrosine is at 0.63 V, thus avoiding interference from L-tyrosine and other amino acids.
