Latest Patents
Xinhua Wan holds a patent for a "Chiral resolution method mimicking magnetic beneficiation and the magnetic nano-inhibitors for selective enrichment." This invention involves a core-shell nanocomposite formed by the co-assembly of an amphiphilic polymer and hydrophobically modified magnetic nanoparticles. The core consists of a hydrophobically modified magnetic nanomaterial, while the shell is made of the amphiphilic polymer. The hydrophilic segments of the polymer are positioned at the outermost layer of the shell. This composite serves as an additive in the crystallization of conglomerates, allowing for the production of optically pure crystals of both enantiomers in a single process. The key innovation lies in the composite's ability to enrich molecules with the same configuration while inhibiting the crystallization of the other enantiomer in a supersaturated solution. This results in the generation of a non-magnetic crystal and a magnetic crystal, which are enantiomers of each other, in a single operation. The process can yield optically pure crystals with over 90% enantiomeric excess and a total yield of up to 40%.
