Application



  • Optical resolution of ephedrine: A study explored the optical resolution of racemic ephedrine using various derivatives of tartaric acid, presenting a method that could refine the production of pharmaceutical-grade ephedrine hydrochloride (Bánhegyi et al., 2022).


  • Stereoselective forensic analysis: Supercritical fluid chromatography coupled with tandem mass spectrometry was used to perform a stereoselective analysis of ephedrine and its isomers in seized methamphetamine samples, offering insights into forensic applications of ephedrine hydrochloride (Segawa et al., 2021).


  • Chiral analysis of stimulants: A chiral high-performance liquid chromatography-tandem mass spectrometry method was applied to determine amphetamine-type stimulants, including ephedrine, in forensic samples, providing a tool for the precise separation and identification of chiral drugs (Schwelm et al., 2020).

We present an approach for synchronizing hyperthermia and thermal-responsive local drug release. The targeting probe has a magnetite nanocrystal (Fe₃O₄@PSMA) core and a polynucleotide shell that carries 5-fluorouracil (5-FU) and anti-human epidermal growth factor receptor 2 (anti-HER2) antibody for cancer
